Search for the Higgs boson decaying to a pair of muons in pp collisions at 13 TeV with the ATLAS detector

The Higgs to dimuon decay is the most promising process to observe the couplings between Higgs Boson and the second generation fermions at the LHC. A search for the dimuon decay of the Higgs boson is performed using the data corresponding to an integrated luminosity of 139 fb$^{−1}$ collected with the ATLAS detector in pp collisions at $\sqrt{s}$ = 13 TeV at the Large Hadron Collider. Events are divided into several regions to target different Higgs production modes using boosted decision trees (BDT). A measurement is then performed with a simultaneous fit to the dimuon mass spectrum in those regions. The analysis and the expected and observed results will be presented.
