Brief annotation and scientific rationale:
The goal of research is to study the physics of pp collisions at the Large Hadron Collider (LHC) using data collected with the CMS detector, corresponding to an integrated luminosity of up to 450 fb-1; data taking, data processing and analysis to obtain new physics results in the following fields:

  • searches for new physics with the dimuon in final states, based on extended gauge models and scenarios with TeV-scale gravity (extra dimension models);
  • searches for dark matter candidates with the dimuon/b-quarks in final states and missing transverse energy;
  • studies of Higgs boson properties and searches for new scalar bosons in lepton decays, predicted by extended Higgs sector;
  • studies of muon pair production in Drell-Yan process to test SM at new energy scale, measurement of weak mixing angle and parton distribution functions (PDF)
  • jet measurements for studies of hadronization, improvement of PDF and QCD coupling precision

The project is also focused on the operation and study of performance of the CMS endcap detectors –  hadron calorimeters (Hadron Endcap, HE) and forward muon stations (Muon Endcap, ME1/1).

 Expected results upon completion of the project:

  1. Experiments with the CMS Detector at the LHC, commissioning and ensuring operation of CMS hadron calorimetry and the forward muon stations during data taking at high luminosity and nominal energy.
  2. Development and realization of physics program to test the Standard Model and searches for physics beyond the Standard Model using data collected with the CMS detector facility at the LHC corresponding to an integrated luminosity of 450 fb−1 at a nominal center-of-mass energy. 

Expected results of the project this year:

  1. Tests of the Standard Model and searches for new physics with high energy muons and missing transverse energy in the final state based on processing and analysis of proton-proton collision data collected with the CMS detector at the LHC at a center-of-mass energy of up to 13.6 TeV, corresponding to an integrated luminosity of up to 300 fb-1; development and improvement of algorithms for reconstruction of high energy muons and jets.
  2. Maintance and operation of the CMS detectors, participation in data taking, data quality monitoring, and shifts.
  3. Development of software for GRID-based distributed system for data processing and analysis. Data transmission between the Tier-1/Tier-2 centers of CMS and JINR.

Brief annotation and scientific rationale:
Starting from 2029 the LHC will be running at luminosity of 7.5×1034 cm-2c-1 (High Luminosity LHC, HL−LHC) that will allow increasing statistics by more than one order of magnitude (Lint ~ 3000 fb−1). The LS 3 for the LHC upgrade to HL−LHC is planned from 2026 to 2029. The main goal of the CMS upgrade in LS3 is to ensure effective work of all subsystems in HL−LHC era.

The main goal of this project is contribution to construction of the Highly Granularity Calorimeter (HGCal) and an upgrade of the CMS ME1/1 Cathode Strip Chambers.

 

Expected results upon completion of the project:

  1. Upgrade of the CMS Detectors with JINR responsibilities to ensure effective operation at high luminosity in pp−collisions at the nominal LHC energy.

Expected results of the project this year:

  1. Upgrade of the forward muon station ME1/1 and participation in gas chambers ageing study and the new gas mixture studies for endcap CSC.
  2. Construction of the experimental facility for complex tests of HGCal active elements.
  3. Development of the technology for manufacturing the HGCal cooling plates.
