Experimental Study of Higgs Bosons in CP-Violating MSSM Scenario at TESLA — •Tatsiana Klimkovich1, Klaus Desch2, Rolf-Dieter Heuer2 und Thorsten Kuhl1 — 1DESY, Notkestrasse 85, 22603 Hamburg — 2Institut für Experimentalphysik, Universität Hamburg, Luruper Chaussee 149, 22761 Hamburg
In the minimal supersymmetric extension of the Standard Model (MSSM) complex phases can be introduced yielding CP-violating effects in the neutral Higgs sector. Three neutral Higgs mass eigenstates H1,H2,H3 are the mixtures of the different CP-eigenstates. We study the sensitivity of a future e+e− linear collider like TESLA to such scenarios. One of the possible production channels is e+e−→ HiHj→ bbbb (i,j=1,2,3). A simulation based on a cut analysis was used to extract the expected uncertainties on the masses and cross-sections. Various possibilities for the reconstruction of the neutral Higgs bosons masses were considered.
These results can be used to constrain the parameter space of the MSSM Higgs sector.
