Abstract

The Muon Collider is a possible option for the next generation of high-energy collider machines. It would permit to achieve very high center-ofmass energy using leptons without occurring in significative synchrotron radiation losses as in positron-electron rings. Due to the muon decay, the detector has to sustain a high level of background: beam decay products and subsequent particles from secondary interactions with the machine elements can reach the interaction point, thus jeopardizing the physical performance of the detector. Nevertheless, this machine offers the possibility of producing huge Higgs boson samples with respect to the backgrounds, allowing the precise determination of the b- and cquark couplings. In this contribution, a study of the identification of b- and c-jets in the Muon Collider environment is presented, and an estimation of the statistical precision on the H → b¯b cross-section is evaluated, accounting for the presence of the beam and the physical backgrounds. A preliminary study on the use of machine learning techniques to improve the result and to study the H → cc¯ will also be reported.
