One–loop corrections to the chargino and neutralino mass matrices in the on–shell scheme Abstract We present a consistent procedure for the calculation of the one–loop corrections to the charginos and neutralinos by using their on–shell mass matrices. The on– shell gaugino mass parameters M and M ′ , and the Higgsino mass parameter µ are defined by the(More)
We present the one-loop corrected decay widths for the decays of the neutral Higgs bosons h 0 , H 0 and A 0 into a neutralino pair˜χ 0 m ˜ χ 0 n (m, n = 1,. .. , 4) and to the decay˜χ 0 m → (h 0 , H 0 , A 0) + ˜ χ 0 n. The corrections contain the one-loop contributions of all fermions and sfermions. All parameters are taken on-shell. This requires a proper(More)
We study effects of CP violation in an associated production of a charged Higgs boson and a top quark at the LHC: pp → tH ± + X. We calculate the CP violating asymmetry between the total cross section for H + and H − production at next-to-leading order in the MSSM, and perform a detailed numerical analysis. In the production only the asymmetry is of the(More)
