The √s=100 TeV proton-proton collider (FCC-hh) is a core part of the Future Circular Collider project. The conceptual design of a suitable detector for FCC-hh is an integral part of this ongoing effort.

Such a detector should be able to operate under luminosities of up to 3x10^35 cm-2s-1, and pile-up conditions of up to ~1000 events per bunch crossing. In addition, the physics program... -

The FCAL collaboration develops the technologies of compact and fast calorimeters with low average power consumption to measure the luminosity both with high precision using small angle Bhabha scattering and bunch-by-bunch using beamstrahlung pairs. For the precision... -

Precision timing detectors have the potential to transform event reconstruction in high energy physics experiments, especially at the LHC where pileup will significantly deteriorate the physics performance. I will be presenting current studies on particle identification at the LHC with enhanced detectors capable of delivering approximately 30 ps time resolution for minimum ionizing particles...

Numerous new physics models, e.g., theories with extra dimensions and various gauge-group extensions of the standard model, predict the existence of new particles decaying to leptons and photons. This talk presents CMS searches for new resonances in the dilepton, lepton+MET, diphoton, and other final states that include leptons and photons, focusing on the recent results obtained using data...

Supersymmetry is one of the best-studied extension of the standard model of particle physics. The talk summarizes the results of searches for supersymmetry performed with the CMS experiment using proton-proton collisions at a centre-of-mass energy of 13 TeV. The searches cover a wide spectrum of final states and are interpreted in the framework of several supersymmetric models.

We consider a scenario inspired by natural supersymmetry, where neutrino data is explained within a low-scale seesaw scenario. We extend the Minimal Supersymmetric Standard Model by adding light right-handed neutrinos and their superpartners, the R-sneutrinos, and consider the lightest neutralinos to be higgsino-like. We consider the possibilities of having either an R-sneutrino or a higgsino...

Torsion models constitute a well known class of extended quantum gravity models. In this work, one investigates phenomenological consequences of a torsion field interacting in different ways with top quarks at LHC. A torsion field could appear as a new heavy state characterized by its mass and couplings to fermions. This new state would form a resonance decaying into a top anti-top pair. The...

The atomic nucleus is one of the most complex strongly-interacting many-body Fermionic systems in nature. A main challenge in describing nuclei is understanding the short interparticle part of the nuclear wave function. Recent high-energy proton and electron scattering experiments show that short-range interactions between the nucleons form correlated, high-momentum, neutron-proton pairs,...

The propagation of colored quarks through the strongly interacting nuclear medium and subsequent formation of hadrons are the phenomena related to the fundamental processes in QCD. There are many experimental tools which can be employed to study those processes. In this talk I will present two results based on the measurements of hadronic final states produced with 5 GeV electron beam in the...

The electromagnetic form factors of the nucleon are essential for our under- standing of the structure of the nucleon. Precision measurements of nucleon form factors constitute a key part the Jefferson Lab experimental program. The proton Radius experiment (pRad), the first experiment to be completed following the 12 GeV beam upgrade of Jefferson lab, measured the proton form factor down to...

A new analysis of published experimental data from the HERMES experiment has been performed. This analysis extracts new information on the space-time properties of color propagation through fitting to a geometric model of the interaction with a realistic nuclear density distribution. Our approach uses a simultaneous fit to the transverse momentum broadening observable and the hadronic...

ALICE is the experiment at the LHC devoted to the study of the strongly-interacting matter produced at high temperature and high energy density in ultra-relativistic heavy-ion collisions. In parallel with the successful operation of the experiment and with the rich physics output obtained during the first two runs of the LHC, the ALICE collaboration is working on a major upgrade of its...

We study the correlation length between test quarks with the same electric and color charges in the Nambu–Jona-Lasinio model, considering thermal and magnetic effects. We extract the correlation length from the quark correlation function. The latter is constructed from the probability amplitude to bring a given quark into the plasma, once a previous one with the same quantum numbers is placed...

The clustering of color sources has been successful in describing several phenomena of multiparticle production, and collectivity signatures of strongly interacting partonic matter in relativistic heavy-ion collisions from the initial stage. Moreover, in small collision systems, the size effects in critical string density becomes relevant, and its contribution to the system properties differ...
