Trilinear Self-Couplings of MSSM Higgs Bosons

Abstract

We present an analysis of multiple production of the CP-even (h0 ,H0) and CP-odd (A0) Higgs bosons as well as of the trilinear self-couplings in the context of the Minimal Supersymmetric Standard Model (MSSM) at the Future International Linear e+e− Collider (ILC). The analysis is based in the reactions e+e− !b¯bhihi with hi = h,H,A.We evaluate the total cross section of b¯bhihi and calculate the total number of events considering the complete set of Feynman diagrams at treelevel. The numerical computation is done for the energy which is expected to be available at the ILC with a center-of-mass energy varies in the range 500 ps 1600 GeV and a luminosity 1000 f b−1.
