Abstract

The precise determination of the masses of the CP-odd and -even heavy Higgs bosons is an important part of the study of Supersymmetry and its relation with cosmology through dark matter. This note presents a determination of the A0 boson mass with the e+e- -> H0A0 -> b b b b process for a dark matter motivated cMSSM scenario with M(A) = 1141 GeV at CLIC. The analysis is performed with full simulation and reconstruction at 3 TeV accounting for beamstrahlung effects. SM and SUSY backgrounds are considered and the effect of the overlay of gamma gamma -> hadrons events on the signal is studied for various assumptions for the detector time-stamping capabilities. The di-jet mass resolution is improved by applying a kinematic fit. The A0 mass can be determined with a statistical accuracy of ~3-5 GeV for 3 inverse ab of statistics and 0 to 20 bunch crossings of gamma gamma background integrated in one event, respectively.
