Description
Future Experiments
The international ePIC collaboration has formed to design and construct the general purpose detector to be ready at the beginning of operation of the Electron-Ion Collider. ePIC will be located at the IP6 interaction region of the RHIC/EIC accelerator. By measuring inclusive and semi-inclusive DIS (where the target is shattered) and exclusive processes (where the target is left intact) in...
EPIC is a general-purpose detector designed to deliver the full physics program of the Electron-Ion Collider (EIC). Particle identification (PID) at the EIC is an essential asset as well as a challenge: the PID systems have to provide excellent separation of pions, kaons, and protons over a large phase space with significant pion/electron suppression. EPIC addresses the physics requirements by...
Excellent particle identification (PID) is one of the key requirements for the central detector of the Electron-Ion collider (EIC). Identification of the hadrons in the final state is important to study how different quark flavors contribute to nucleon properties. A detector with a radial size of only 7-8 cm, which uses the principle of Detection of Internally Reflected Cherenkov light (DIRC),...
The physics program at the High Luminosity LHC (HL-LHC) calls for a precision in the luminosity measurement of 1%. A larger uncertainty would represent the dominant systematic error in several precision measurements, including in the Higgs sector. To fulfil this requirement in an environment characterized by up to 140 simultaneous interactions per bunch crossing (200 in the ultimate scenario),...
The Tile Calorimeter (TileCal) is a sampling hadronic calorimeter covering the central region of the ATLAS experiment, with steel as absorber and plastic scintillators as active medium. The High-Luminosity phase of LHC, delivering five times the LHC nominal instantaneous luminosity, is expected to begin in 2029. TileCal will require new electronics to meet the requirements of a 1 MHz trigger,...
The possibility of a joint interaction region and detector which could study ep/eA and pp/pA/AA at the HL-LHC was presented in [1]. Here we show the most recent developments on the design of such novel interaction region where, in ep/eA mode, one hadron or nuclear beam must go through the region unscathed while in hh mode that beam must be focused to collide with the other hadron or nuclear...
The Large Hadron-electron Collider and the Future Circular Collider in electron-hadron mode [1] will make possible the study of DIS in the TeV regime providing electron-proton (nucleus) collisions with per nucleon instantaneous luminosities around $10^{34}$ ($10^{33}$) cm$^{-2}$s$^{-1}$. Here we describe the current detector design for such experiments [1,2] and the key developments needed,...
In the high-luminosity era of the Large Hadron Collider, the instantaneous luminosity is expected to reach unprecedented values, resulting in up to 200 proton-proton interactions in a typical bunch crossing. To cope with the resulting increase in occupancy, bandwidth and radiation damage, the ATLAS Inner Detector will be replaced by an all-silicon system, the Inner Tracker (ITk). The innermost...
ATLAS-ITK Strip Collaboration
(the speaker to be selected by the ITk Speakers Committee after the contribution acceptance)
The inner detector of the present ATLAS experiment has been designed and developed to function in the environment of the present Large Hadron Collider (LHC). At the ATLAS Phase-II Upgrade, the particle densities and radiation levels will exceed current levels by a...
There has been significant discussion in the community regarding a future $\mu^+\mu^-$ collider. While such a facility is still decades away from realization, it is also understood that significant technological development and feasibility demonstrations are necessary at lower beam energies. Here we propose such a possibility coupled with a rich physics program. We propose a future Muon-Ion...
The EIC physics program relies on successful measurements of exclusive final states, which produce charged particles (e.g. protons, pions) at far-forward pseudorapidities. Such particles are within a few millimeters of the outgoing hadron beam. Reconstruction of these particles requires use of silicon detectors placed directly into the accelerator vacuum, in the style of the Roman Pots used ...
A new era of hadron collisions will start around 2029 with the High-Luminosity LHC which will allow to collect ten times more data than what has been collected during 10 years of operation at LHC. This will be achieved by higher instantaneous luminosity at the price of higher number of collisions per bunch crossing.
In order to withstand the high expected radiation doses and the harsher...
The ATLAS Muon Spectrometer is designed to provide Muon triggering, identification and momentum measurement. It consists of resistive plat chambers (RPCs) and thin gap chambers (TGCs) that are used as primary trigger detectors, while monitored drift tubes (MDTs) and cathode strip chambers (CSCs) are utilized for precision trackering. To improve the Muon transverse momentum (pT) resolution at...
The Large Hadron Collider (LHC) at CERN is the largest and most powerful particle collider today. The Phase-II Upgrade of the LHC will increase the instantaneous luminosity by a factor of 7 leading to the High Luminosity LHC (HL-LHC). At the HL-LHC, the number of proton-proton collisions in one bunch crossing (called pileup) increases significantly, putting more stringent requirements on the...
SND@LHC is a compact and stand-alone experiment to perform measurements with neutrinos produced at the LHC in a hitherto unexplored pseudo-rapidity region of 7.2 < 𝜂 < 8.6, complementary to all the other experiments at the LHC. The experiment is located 480 m downstream of IP1 in the unused TI18 tunnel. The detector is composed of a hybrid system based on an 800 kg target mass of tungsten...
The IceCube Neutrino Observatory is a Cherenkov detector located at the South Pole, instrumented in a cubic kilometer of ice. The DeepCore subdetector, at the lower center of the IceCube array, has a denser configuration and has allowed us to see GeV-scale neutrinos, which improves the sensitivity to atmospheric neutrino oscillations. Precious reconstruction is critical to neutrino oscillation...
PERLE is a facility to probe high-current multiturn energy recovery to be built at IJClab in Orsay. Besides being a key step towards the use of this technology, one of the priorities established in the last European Strategy for Particle Physics [1], in top energy colliders, it will also provide a strong physics programme on its own. We review the status of PERLE and the steps from the...
The constituents of dark matter are still unknown, and the viable possibilities span a very large mass range. Specific scenarios for the origin of dark matter sharpen the focus on a narrower range of masses: the natural scenario where dark matter originates from thermal contact with familiar matter in the early Universe requires the DM mass to lie within about an MeV to 100 TeV. Considerable...
The LUXE experiment (Laser Und XFEL Experiment) is an experiment in planning at DESY Hamburg using the electron beam of the European XFEL. LUXE is intended to study collisions between a high-intensity optical laser pulse and 16.5 GeV electrons from the XFEL electron beam, as well as collisions between the laser pulse and high-energy secondary photons. This will elucidate quantum...
Missing abstract
A fixed target experiment, HERCULES, similar to HERMES but with 500 times higher electron-nucleon luminosity, at EIC will allow a big advance in hadron physics. The internal target with the polarized hadron beam also has an important physics program. The high intensity photon beam will allow to study photo-production of the $c\bar c$ excited states and recently discovered XYZ states. We will...
Long-baseline neutrino oscillation experiments present some of the most compelling paths towards beyond-the-standard-model physics through measurement of PMNS matrix elements and observation of the degree of leptonic CP violation. State-of-the-art long-baseline oscillation experiments, like NOvA and T2K, are currently statistically limited, however uncertainty in neutrino-nucleus scattering...
Coherent electro-production of $J/\psi$ on $^4$He offers a unique opportunity to explore the gluonic component of its matter distribution directly. The gluonic matter form factor of $^4$He can be experimentally accessed by performing a measurement of the reaction $^4 He(e, e' ^4He)J/\psi$ where the $J/\psi$ is reconstructed via missing mass. Such measurement requires the coincidence detection...
This talk will discuss future tagged deep inelastic scattering (TDIS) measurements in Hall A of Jefferson Lab, which will directly probe the elusive mesonic content of the nucleon via the Sullivan process. The idea that the nucleon’s mesonic content could be explored through electron nucleon deep inelastic scattering has a long history with the Sullivan process. However, even after five...
The Liquid Argon Calorimeters are employed by ATLAS for all electromagnetic calorimetry in the pseudo-rapidity region |η| < 3.2, and for hadronic and forward calorimetry in the region from |η| = 1.5 to |η| = 4.9. They also provide inputs to the first level of the ATLAS trigger. After successful period of data taking during the LHC Run-2 between 2015 and 2018 the ATLAS detector entered into the...
Experimental uncertainties related to hadronic object reconstruction can limit the precision of physics analyses at the LHC, and so improvements in performance have the potential to broadly increase the impact of results. Recent refinements to reconstruction and calibration procedures for ATLAS jets and MET result in reduced uncertainties, improved pileup stability and other performance gains....
Hadronic object reconstruction is one of the most promising settings for cutting-edge machine learning and artificial intelligence algorithms at the LHC. In this contribution, selected highlights of ML/AI applications by ATLAS to particle and boosted-object identification, MET reconstruction and other tasks will be presented.
Muon reconstruction performance plays a crucial role in the precision and sensitivity of the Large Hadron Collider (LHC) data analysis of the ATLAS experiment. Using di-muon Resonances we are able to calibrate to per-mil accuracy the detector response for muons. Innovative techniques developed throughout the Run-2 period and during the collider's shut-down significantly improve the measurement...
Presentation of the performance of the trigger system of the CMS experiment in Run 2 and the first year of Run 3 of the LHC.
The CMS experiment at CERN underwent several detector upgrades before the Large Hadron Collider (LHC) Run 3 started in 2022, delivering integrated proton collision luminosity of 38 fb-1 to CMS. LHC will continue with the planned proton-proton and lead ion collision programmes until the Run-3 concludes in 2025.
During High Luminosity operations (2029-2038), LHC is expected to deliver 3000 fb-1...
Generalized parton distributions (GPDs) are off-forward matrix elements of quark and gluon operators that work as a window to the total angular momentum of partons, making it possible to solve the spin puzzle that emerged after EMC measurements. In addition, GPDs enable tomography of the nucleon allowing to study spatial distribution of partons as a function of momentum, providing clear...
Since the EMC collaboration measurement of the small quark spin contribution to the proton spin in the late 1980s, the nuclear physics community has been actively working to resolve the so-called proton spin puzzle. While the size of the quark spin contribution is fairly well established, the gluon spin contribution is not as well established and recently has met theoretical tension. Recent...
Solenoidal Large Intensity Detector (SoLID) is a large acceptance, high luminosity device proposed for exploiting the full potential of the Jefferson Lab 12 GeV energy upgrade. The scientific program of SoLID includes three semi-inclusive deep inelastic scattering (SIDIS) experiments with multiple run-group experiments. One of the major tasks of SoLID is to deepen our knowledge of the nucleon...
In this talk, we will provide an overview of future parity violation deep inelastic scattering (PVDIS) experiments by using the Solenoidal Large Intensity Device (SoLID) at Jefferson Lab (JLab) Hall A. We will obtain data with high statistic and large kinematic coverage for Bjorken $0.25
A precision measurement of inclusive neutron spin structure function $g_{2} (x,Q^{2})$, will be run in parallel with SIDIS experiments E12-010-006 (transversely polarized $^{3}$He target) and E12-11-007 (longitudinally polarized $^{3}$He target) by using a Solenoidal Large Intensity Device (SoLID) at Jefferson Lab (JLab) Hall A, as has been approved by JLab PAC48 in 2020. In the proposed...
The Large Hadron-electron Collider and the Future Circular Collider in electron-hadron mode [1] will make possible the study of DIS in the TeV regime providing electron-proton collisions with per nucleon instantaneous luminosities around $10^{34}$ cm$^{-2}$s$^{-1}$. In this talk we will review the opportunities for measuring standard and anomalous top couplings, both to lighter quarks and to...
The dependence of the top-quark mass measurement in top-quark production on the parton distribution functions (PDF) is explored through differential mass distributions in $t\bar{t}$ and $t\bar{t}j$ production at the LHC and a future 100 TeV proton-proton collider. The top-quark mass uncertainty is obtained from chi-squared fits to invariant mass distributions from simulations assuming...
We review the status of the Large Hadron-electron Collider and the Future Circular Collider in electron-hadron mode after the publication of the update of the 2012 Conceptual Design Report in [1] and the studies on a joint $eh-hh$ interaction region and experiment in [2]. We also comment on the main technical challenges of these proposals and describe further steps of work towards the Update...

We review the possibilities for detection of physics beyond the SM in these machines, focusing on feebly interacting particles...
A renewed attention has spawned in recent years to the pion parton distribution functions (PDFs). In 2018, the JAM collaboration included not only the pion-induced Drell-Yan data from Fermilab’s E615 experiment but additionally the leading neutron electroproduction data from HERA for the first time in a global QCD analysis. Unfortunately, further useful experimental data have been scarce. With...
The future electron-ion collider (EIC) will provide the first electron-nucleus collisions for a variety of nuclei species with high luminosity, wide kinematic coverage, and excellent detector resolution, providing new insights into cold nuclear matter effects and transport phenomena. As jets are an accurate proxy of the struck quark that traverses the nucleus, the signature of the nuclear...
Generalized Parton Distributions (GPDs) open a new avenue in our understanding of nucleon structure that may shed light on many properties of the nucleon such as spin, mass and 3D images of a completely relativistic QCD system. This is achieved by measuring both transverse and longitudinal properties of the nucleon simultaneously. Extraction of GPDs presents a formidable experimental...
Inclusive Diffractive Deep Inelastic Scattering ($ep \rightarrow eXp$) is mediated by the $t$-channel exchange of net-colourless strongly interacting objects related to mesons and to the pomeron. The high performance beam-line proton spectrometers and central detector components that are included in detector designs for the future Electron Ion Collider will lead to measurements of this process...
The EIC's high luminosity, wide kinematic coverage, availability of proton and isoscalar deuteron targets, and ability to polarize both the lepton and hadron beams, allows for unique opportunities for precision tests of the electroweak sector of the Standard Model and constraining beyond the Standard Model physics in a manner that complements efforts at the LHC and low energy experiments. In...
Measurements in semi-inclusive deep inelastic scattering provide a wide range
of insights into nucleon structure and hadronization. Spin asymmetries and
cross sections in single-hadron and dihadron production are sensitive to
various combinations of transverse momentum-dependent (TMD) distribution and
fragmentation functions, depending on the polarizations of the initial electron
and...
In this talk, we will discuss the physics prospects of photon-induced measurements using the high granularity FoCal detector to be installed at the ALICE experiment, covering the pseudorapidity interval $3.4 \leq \eta \leq 5.8$. This new detector, scheduled to be in operation from Run 4, will explore the small Bjorken-$x$ physics region in an unprecedented way. In this region the gluon...
The High-Luminosity Large Hadron Collider (HL-LHC) is expected to deliver an integrated luminosity of up to 3000 fb-1. The very high instantaneous luminosity will lead to about 200 proton-proton collisions per bunch crossing (“pileup”) superimposed to each event of interest, therefore providing extremely challenging experimental conditions. Prospects for SM measurements and searches for beyond...
