SUSY-QCD corrections to stop and sbottom decays into Higgs bosons
A. Bartl, H. Eberl, K. Hidaka +4
We calculate the order(α_s) SUSY-QCD corrections to the widths of stop and sbottom decays into Higgs bosons within the Minimal Supersymmetric Standard Model. We give the complete a…
Sfermion Pair Production at Colliders
A. Bartl, H. Eberl, S. Kraml +2
We discuss pair production of stops, sbottoms, staus and tau--sneutrinos at a collider. We present the formulae for the production cross sections and perform a detailed n…
Spin Correlations in Production and Decay of Charginos
G. Moortgat-Pick, H. Fraas, A. Bartl +1
We study the production of charginos e^+ e^- -> chi^+_i chi^-_j, (i,j=1,2) with polarized beams and the subsequent decays chi^+_i -> chi^0_k ell^+ nu and chi^-_j -> chi^0_l ell^- n…
Bosonic decays of stop_2 and sbottom_2
A. Bartl, H. Eberl, K. Hidaka +5
We perform a detailed study of the decays of the heavier top and bottom squarks (stop_2 and sbottom_2) in the Minimal Supersymmetric Standard Model (MSSM). We show that the decays…
CP violating angular asymmetries of b and bbar quarks in e+e- -> t tbar
A. Bartl, E. Christova, T. Gajdosik +1
We obtain analytical formulae for the cross section and the angular distributions of the b(bbar) quarks in the process e+e- -> t tbar, with t -> W+ b (tbar -> W- bbar) assuming CP…
Spin Effects in Neutralino Production in Annihilation with polarized beams
G. Moortgat-Pick, H. Fraas, A. Bartl +1
We study the process e^+ e^- -> chi^0_1 chi^0_2 and the subsequent decay chi^0_2 -> chi^0_1 l^{+} l^{-}.…
