The cms detector | CMS Experiment
ويب2 days ago · CMS at LHCP 2024. CMS has released 12 new results for the spring conferences (LHCP 2024, SQM 2024, and SUSY24), spanning its entire physics program: - Studying high momentum top quark-antiquark pairs, we have observed, for the first time, entanglement between top quar….
Upgrading the LHCb sub-detectors for the HL-LHC | CERN
ويب1 day ago · On 5 July 2022, protons began colliding again in the LHCb detector after a three-and-a-half-year break known as Long Shutdown 2 (LS2), marking the start of the third run of the Large Hadron Collider (LHC). During this period, the original LHCb detector at the LHC was largely dismantled and an almost completely new detector constructed. The 2020 …

Development of the CMS detector for the CERN LHC Run 3
ويب23 مئی، 2024 · Thispaper discusses the CMS detector as it is configured for the thirddata-taking period of the CERN LHC, Run 3, which started in2022. The entire silicon pixel tracking detector was replaced. A newpowering system for the superconducting solenoid was installed.
HiLumi News: The HL-LHC’s cold powering system successfully
ويب28 مئی، 2024 · This new system is packed with novel superconducting technologies: MgB 2 superconducting cables, twisted together to form a compact bundle of about 9 centimetres in diameter, are inserted into a 22-centimetre-diameter flexible cryostat, with vacuum insulation and flowing helium gas.
Design and construction of the CMS Inner Tracker for the HL-LHC …
ويب19 مئی، 2024 · The Inner Tracker has been redesigned for HL-LHC featuring new sensors and readout electronics, high granularity with smaller pixels and additional layers, reduced material budget and increased tracking acceptance.
Overview of high-density QCD studies with the CMS experiment at the LHC
ويب17 مئی، 2024 · This article summarizes key QCD, QED, as well as BSM physics, results of the CMS HI program for the LHC Runs 1 (2010-2013) and 2 (2015-2018). It reviews findings on the partonic content of nuclei and properties of the QGP and describes the surprising QGP-like effects in collision systems smaller than lead-lead or xenon-xenon.
Searching for Long Lived Particles at LHC - arXiv.org
ويب28 مئی، 2024 · Search for BSM phenomena is one of the fundamental goals of the LHC experiments. Many BSM models foresee long-lived particles which decay far from the production vertex and a big efort has been done by the ATLAS and CMS collaborations to detect these long-lived particles.
Symmetry | Free Full-Text | Results and Perspectives from the
ويب1 day ago · After rapid approval and installation, the SND@LHC Collaboration was able to gather data successfully in 2022 and 2023. Neutrino interactions from νμs originating at the LHC IP1 were observed. Since muons constitute the major background for neutrino interactions, the muon flux entering the acceptance was also measured. To improve the …
