Squark Pair Production at Muon Colliders in the MSSM with CP Violation

Abstract

We study the pair production of scalar quark in a muon collider within the MSSM with CP violation. We show that including the CP phases can strongly affect the cross section of the process: μ + μ − →q iqj . This could have an important impact on the search for squarks and the determination of the MSSM parameters at future colliders.

Squarks Decay into Quarks and Gluinos in the MSSM with Complex Parameters

“…Studies of the third generation squarks are particularly interesting because of the effects of the large Yukawa couplings. A number of studies of squarks production and decay within the MSSM with complex parameters are also available: the effect of the CP phases on the cross sections of squarks prodution at e + e − and µ + µ − colliders has been presented in [3,4] with SUSY-QCD corrections included. CP phase dependences of the stop and sbottom (t 1,2 andb 1,2 ) partial decay widths and branching ratios have been investigated for the fermionic decays [5,6,7,8] and for the bosonic decays…”
