Comments for Referee Reports “As far as the planned data analysis activities, the JINR group intends to mainly address muon pair production (Drell-Yan). Although mentioned in the report, it is not clear to the referee which have been and will be the JINR contributions to the search for physics beyond the SM and to the studies on the Higgs. On the other hand, there have been clear contributions on jet production studies, which will likely be continued. ” The JINR taken part in Dimuon Physics Program since 2002 (as one of the initiators of this program). JINR participates in all steps of this analysis: from event registration and selection up to final physics analysis. ü We study of muons and a muon pairs as the physics objects in CMS Muon Detector Performance Group and Muon Objects Group ü We take part in Physics Analysis within in three Physics Analysis Group: EWK, Exotica, and Higgs ü In 2017 -2018 we contribute in to 3 CMS papers (4 CMS Analysis Notes) for physics beyond the Standard Model (Exotica) and 1 CMS paper (2 CMS Analysis Notes) for Higgs Physics. ü We also contribute in to CMS physics performance studies for these searches (for HL -LHC) All information is available in the Project. “CMS. Compact Muon Solenoid at LHC”, 19 June 2019 г. , PAC for PP

Comments for Referee Reports “As far funding is concerned, pending a final agreement on the future contributions, there are fixed shares such as fees per author that must be taken into account. In this respect, in recent years there has been a strong reduction of the number of authors (from 60 to 22) to cope with shortage of funding. The final balance of expenses in 20172019 seems to indicate a cost not completely commensurate to the scientific deliverables, in particular with the number of scientific publications driven by the JINR group. ” ü As we show before the number of JINR Authors in CMS <1% of all CMS Authors. Nevertheless, JINR contribution to the CMS papers reaches 2. 6% for the last three years. ü In total we have 23 paid authors. In accordance with Maintenance & Operation of the experimental facility (M&O category A) the JINR had to be paid 268 KCHF for 2019. We ask for both categories A and B only 227 KCH. ü There was a useful practice of sending one employee of JINR to CERN to work in the CMS Secretariat, which leads to a compensation payment JINR costs ~ 8 authors. “CMS.

Comments for Referee Reports “This will probably require a thorough internal discussion and an optimization of the person power resources. This issue is also closely related to the upgrade contributions which will be eventually decided. ” üWe would like to stress that this project concerned to ongoing activities (detector maintenance and R&D, data taking and physics analysis) for 2020 -2023 for Run 3. üThe JINR contribution to the CMS Phase 2 Upgrade is under discussion. The relevant JINR Projects will follow, when CMS will take the technical decision. “CMS. Compact Muon Solenoid at LHC”, 19 June 2019 г. , PAC for PP

Why Di-muons? • Many theoretical reasons: verification of Standard Model with Drell-Yan processes, hunting for new physics beyond SM (extra gauge models, extra dimensions etc) • Cross-sections of hadron signatures are higher, but leptonic decays provide clear signatures with lower and controllable backgrounds! • Why muons? Because it is Compact MUON Solenoid where Dubna group plays important role since conceptual design through Ph. TDR up to physics analysis – strong B-field and long lever arm (from IP and tracker to Muon system) for precise momentum estimation – high precision muon detectors with redundant muon trigger priority in JINR physics program – search for new physics in di-muon channels at the invariant mass region uncovered so far by other accelerators RDMS Participation (JINR + Belarus): from theoretical studies up to final physics analysis, including Ø Ø high efficiency of registration, triggering and reconstruction for muons validations software with Monte-Carlo data, muon cosmic data, SPS and LHC beams studies of systematic effects (misalignment, material non-uniformities, B-filed, miscalibration etc) physics analysis “CMS.
