SHIP is a new general purpose fixed target facility, whose Technical Proposal has been recently reviewed by the CERN SPS Committee and by the CERN Research Board. The two boards recommended that the experiment proceeds further to a Comprehensive Design phase in the context of the new CERN Working group "Physics Beyond Colliders", aiming at presenting a CERN strategy for the European Strategy...
We discuss the physics opportunities [1] which are offered by a next generation and multi-purpose fixed-target experiment exploiting the LHC beams. The multi-TeV LHC proton beam grants the most energetic fixed-target experiment ever performed, to study pp, pd and pA collisions at sqrt(s_NN) ~ 115 GeV. AFTER@LHC -- for A Fixed-Target ExperRiment -- gives access to new domains of particle and...
The 12 GeV CEBAF Upgrade at Jefferson Lab is greatly expanding the scientific capabilities for nuclear physics by doubling the maximum energy of the electron accelerator, constructing and operating a fourth experimental Hall, and upgrading the equipment in the existing three Halls. The early science program is underway with full, four Hall operations anticipated this year. The status of the...
From the mid-2020s, the Large Hadron Collider will run as High Luminosity LHC (HL-LHC) with a centre of mass energy of 14 TeV and an instantaneous luminosity of 5-7 x 10^34 cm^-2 s^-1. It aims to collect a total integrated luminosity of 3000 fb-1 by about 2037.
The unprecedented amount of data collected by the upgraded ATLAS detector at the HL-LHC will be used to make precision measurements...
We discuss the physics reach of LHeC and FCC-he for BSM Higgs and di-Higgs production. In particular we also discuss invisible Higgs decay scenario. A detector level studies with speculated parameters have been performed for these channels.
The Georgi-Machacek (GM) model is one of many beyond standard model scenarios
with an extended scalar sector which can group under the custodial SU(2) symmetry
into a fiveplet, a triplet, and two singlets. We study the prospects for detecting the doubly-charged Higgs boson ($\rm H_5^{\pm\pm}$) through the vector boson fusion with same-sign leptons decay channel at the Large Hadron Electron...
In this talk I will give an overview over the searches for sterile neutrinos at electron-proton colliders, discuss the most important signatures, and present the complementarity with searches at proton-proton and electron-positron colliders.
Jefferson Lab Electron Ion Collider (JLEIC) is a proposed realization of the Electron-Ion Collider project in the US. It builds on the existing CEBAF accelerator as the full energy electron injector and adds an ion complex to achieve the luminosity and energy requirements. The current status of the design will be discussed.
The possibility of a very high energy electron-proton (VHEeP) collider with a
centre-of-mass energy of 9 TeV has been presented previously. Further developments are here discussed, summarising the results from a recent publication and highlighting opportunities for more investigation. At the VHEeP collider, with a centre-of-mass energy 30 times greater than HERA, parton momentum fractions,...
We examine the constraints that future lepton colliders would impose on the top-quark effective field theory. All top-quark operators are simultaneously included and their effects are computed at next-to-leading order in QCD, in the MadGraph_aMC@NLO framework, including off-shell top effects.
A detector for the proposed the Jefferson Lab realization for the Electron-Ion Collider is being developed. Current status will be described.
The large data samples at the High-Luminosity LHC will enable precise measurements of the Higgs boson and other Standard Model particles, as well as searches for new phenomena such as supersymmetry and extra dimensions. To cope with the experimental challenges presented by the HL-LHC such as large radiation doses and high pileup, the current Inner Detector will be replaced with a new...
The Tile Calorimeter (TileCal) is the central hadronic calorimeter of the ATLAS experiment at the LHC. Jointly with the other calorimeters it is designed for reconstruction of hadrons, jets, tau-particles and missing transverse energy. It also assists in muon identification. A summary of the upgrades and performance results for TileCal using pp collisions from the LHC Run II at 13 TeV will be...
The 2015 nuclear physics long-range plan endorsed the realization of an electron-ion collider (EIC) as the next large construction project after the completion of FRIB.
With its high luminosity ( $> 10^{33} cm^{-2}s^{-1}$), wide kinematic reach in center-of-mass-energy (45 GeV to 145 GeV) and high lepton and proton beam polarization, the EIC provides an unprecedented opportunity to reach new...
