Pair production of heavy MSSM charged and neutral Higgs bosons in multi-TeV e(+)e(-) collisions at the Compact Linear Collider

• In the theoretical framework of the minimal supersymmetric extension of the standard model (MSSM), we study the pair production of heavy charged and neutral Higgs bosons in e+e- collisions with a center-of-mass energy of 3 TeV, at the Compact Linear Collider (CLIC). The high-energy beam-beam effects at the interaction point are taken into account in our simulations. With an integrated luminosity of 3000fb-1, the hadronic cascade decays of H+H- and A0H0 pairs can be observed over a wide range of Higgs boson masses, extending beyond 1 TeV. The Higgs mass parameter mA can be derived from a χ2-analysis, and the corresponding statistical error was found to be smaller than 1%. In addition, by comparing the signal rates of different decay channels, one can determine the ratio between the vacuum expectation values tan β with a good accuracy in the intermediate region, i.e. when tan β lies between 6 and 11 typically.
