The Large Hadron Collider at CERN has raised its collision energy, and collision rate, since the discovery of the Higgs boson in 2012. This provides a huge, rapidly growing, data sample enabling increasingly sophisticated studies of the Higgs boson, including of its production and decay, from which the couplings to the other Standard Model particles can be inferred. The large data sample also...
At the Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN), protons and heavy ions are made to collide together near the speed of light to study particle interactions and give us an insight to the fundamental laws of nature. Three experiments that are located on the circular ring of the LHC specialize in proton-proton collisions, namely a toroidal LHC apparatus...
The models of atomic nuclei as we know them today have largely been developed based on results from experiments using stable isotopes as beams and targets, or from beta-decay experiments following fission or spallation. However, such experiments have inherent limitations. Due to the tendency of the heavier elements to have a neutron excess compared to the number of protons, an effect of...
After a short introduction to neutrino physics in general the lecture will focus on accelerator-based neutrino-oscillation experiments. A summary of the current status and results of running experiments, in particular NOvA and T2K will be given, to be followed by an overview of the status of the proposed long-baseline experiments Hyper-K, DUNE and ESSnuSB with a special focus on the potential...
We will review the most relevant results on heavy-ion physics at ultra-relativistic energies. This will include a brief overview of the current status on the characterization of the QGP medium created in a heavy-ion collision and will also touch on the intriguing finding of collective-like phenomena exhibited by results obtained in small collision systems.
Feynman integrals are important for describing elementary particle interactions in quantum field theory. From the mathematical point of view, they give rise to interesting special functions. The latter can be computed from differential equations that the integrals satisfy. I will review methods for transforming the equations to a canonical form, from which the answer can be conveniently read off.
We investigate the parameter space in which the dark photon may still explain the muon g-2 anomaly. We consider a model of an inelastic dark sector which couples directly to the dark photon. This scenario may lead to semi-visible decays of the dark photon leading to a parameter space in which the dark photon interpretation of the muon g-2 anomaly may still be viable as opposed to both...
Implementation of gas type emulation in the digitization software of the ATLAS TRT. The primary purposes of emulation are to be able to accommodate for a sudden change in the gas mixture used for data, and for efficiently simulating different gas type geometries to test particle identification performance.
Cosmological and astrophysical observations strongly support the presence of a non-baryonic dark matter component in the universe. A broad search program was designed to look for dark matter particles in the cosmos, either by searching for direct interaction or dark matter annihilation. Alternatively, dark matter particles might be produced in the laboratory. The Large Hadron Collider (LHC)...
Hidden sector or dark sector states appear in many extensions to the Standard Model, to provide a candidate for the dark matter in the universe or to explain astrophysical observations of positron excesses. A hidden or dark sector can be introduced with an additional U(1)d dark gauge symmetry. The presence of the dark sector could be inferred either from deviations from the SM-predicted rates...
The Large Hadron Collider (LHC), which is the world’s largest and most powerful particle accelerator, will be upgraded from 2024 to mid 2026 to become the High Luminosity LHC (HL-LHC). This will enable instantaneous peak luminosities of 7.5 × 1034 cm−2 s−1 and allow CMS to collect integrated luminosities of the order of 300 fb−1 per year and up to 3000 fb−1 during the HL-LHC projected lifetime...
This talk would present the HL-LHC upgrade program of the ATLAS detector. High luminosity constraints and expected performances will be covered. A review of the planned upgrades for the Tracking system (ITK), the muon spectrometer, level-0 and HLT trigger and the new high granularity timing detector (HGTD). Finally, expectations on SM and Higgs boson measurements as well as searches for new...
Despite their frequent use, the hadronic models implemented in Geant4 have shown severe limitations in
reproducing the measured yield of secondaries in ions interaction below 100 MeV/A, in term of
production rates, angular and energy distributions [1,2,3]. We will present a benchmark of the Geant4
models with double-differential cross section and angular distributions of the secondary...
This presentation will report on experiments that study rare reactions that require challenging data sets and running times to search for Physics phenomenon within the Standard Model and Physics beyond the Standard Model. A general survey of some recent results, current research and future experiments primarily at Fermilab will be featured.
For efficient exploitation of research reactors, it is important to discern neutron flux distribution inside the reactor with the best possible precision. For this reason, fission and ionization chambers are used to measure the neutron field. In these arrays, the sequences of the neutron interaction points in the fission chamber can correctly be identified in order to obtain true neutron...

Hidden sector or dark sector states appear in many extensions to the Standard Model, to provide a candidate for the dark matter in the universe or to explain astrophysical observations of positron excesses. A hidden or dark sector can be introduced with an additional $U(1)_d$ dark gauge symmetry. The presence of the dark sector could be inferred either from deviations from the SM-predicted...

The low-energy structure of the stable light nucleus 20Ne has been examined using Coulomb excitation at the TRIUMF Facility in Vancouver, Canada. The highly-efficient and segmented TIGRESS HPGe gamma-ray array permits accurate Coulomb-excitation studies of the high-lying 2^+ state found in 20Ne. Beams of 20Ne(5+) at approximately 1.7x10^7 ions/s were accelerated to 3.235 MeV/u and bombarded...

Nuclear Forensics (NF) involves the laboratory analysis of intercepted nuclear and radiological material (NRM) for nuclear attribution ( origin and intended use). The aim of NF analysis is to establish the relationship between seized NRM and their attribution to monitor and strengthen nuclear security. The critical challenge in NF at the moment is the lack of direct, rapid and non-invasive...
Abstract:
A search for a heavy resonance decaying to WZ in the fully leptonic channel is performed. It is based on proton-proton collision data collected by the ATLAS experiment at the Large Hadron Collider at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 36.1/fb. No significant excess is observed over Standard Model predictions and limits are set on the...
