Description
abstract: This talk will discuss recent searches for the evidence of hidden sectors predicted in
several classes of models beyond Standard Model embarking on explaining a range
of phenomena from the baryon asymmetry and dark matter in the Universe to
addressing the issue of fine tuning required by a light Higgs boson. Many of these
models predict existence of new bosons that only very weakly couple to the
Standard Model particles making them virtually undetectable in earlier
experiments.
The LHC can provide access to these particles via the
production of Higgs bosons that can contain these new hidden particles
in their decay products. Searches for the new boson decays using muon
pairs provides an exceptional sensitivity due to the striking
signature and low background contamination. This analysis relies
heavily on the excellent performance of the CMS detector's muon system.
As most of the final LHC dataset will be collected at ultra high luminosity, the
ultimate sensitivity of the LHC to this and other rare signatures will be
determined by the performance of the detectors during that period. In the
second part of the talk, we will discuss the CMS plans for the upgrades of the
muon detectors and the expected performance in the high luminosity LHC
regime.
