Prospects of measuring the branching fraction of the Higgs boson decaying into muon pairs at the International Linear Collider

The prospects for measuring the branching fraction of H → μ + μ - at the International Linear Collider (ILC) have been evaluated based on a full detector simulation of the International Large Detector (ILD) concept, considering centre-of-mass energies ( s ) of 250 GeV and 500 GeV with two different...

Zusammenfassung:The prospects for measuring the branching fraction of H → μ + μ - at the International Linear Collider (ILC) have been evaluated based on a full detector simulation of the International Large Detector (ILD) concept, considering centre-of-mass energies ( s ) of 250 GeV and 500 GeV with two different beam polarisation configurations of P ( e - , e + ) = ( - 80 % , + 30 % ) and ( + 80 % , - 30 % ) . For both s cases, the two final states e + e - → q q ¯ H and e + e - → ν ν ¯ H have been analyzed. For integrated luminosities of 2 ab - 1 at s = 250 GeV and 4 ab - 1 at s = 500 GeV, the combined precision on the branching fraction of H → μ + μ - is estimated to be 17%. The impact of the transverse momentum resolution for this analysis is also studied.
