A Study of Heavy Higgs Properties at a Multi-TeV e+e- Collider

Abstract

The precise determination of the masses of the neutral and charged heavy Higgs bosons is a crucial input for the study of Supersymmetry and its relation with cosmology through dark matter. This paper presents a study of e+e- -> HA and H+H- production at sqrts=3 TeV. The analysis is performed with full simulation and reconstruction accounting for beamstrahlung effects and the overlay of gamma gamma -> hadrons events. Results are presented in terms of the accuracy on the determination of the masses and widths of the heavy Higgs bosons in two benchmark scenarios.
