Study on discharge and short circuit generation in CMS GE1/1 triple-GEM detectors during Run 3 Open
The installation of the new GE1/1 station of Gas Electron Multiplier (GEM) detectors in the Compact Muon Solenoid (CMS) experiment was completed during the Long Shutdown 2 (LS2) phase of the Large Hadron Collider (LHC). The GE1/1 station h…

Quality Control results of the first CMS GEM GE2/1 muon production chambers Open
The CMS upgrade for the High Luminosity phase of the LHC involves the installation of three GEM stations GE1/1, GE2/1, and ME0. While GE1/1 has been operational since Run-3's onset, only two GE2/1 chambers are in place as of early 2024. ME…

Event characterization of dark bosons via exotic Higgs decays with final states of displaced dimuons in high luminosity era of the LHC Open
We investigate the potential reach of a search for a long-lived/prompt dark vector boson $Z_D$, also called dark $Z$, and a prompt dark Higgs boson $h_D$ through exotic decays of the observed Higgs boson $h$ into either $Z_DZ_D$, $h_Dh_D$,…

Single-photon emission associated with double electron capture incollisions Open
Radiative double electron capture (RDEC), the one-step process occurring in ion-atom collisions, has been investigated for bare fluorine ions colliding with carbon. RDEC is completed when two target electrons are captured to a bound state …
