Oblique corrections in the mssm at one loop II: fermions. (English) Zbl 1260.81306

Summary: This paper is the completion of the authors earlier work [arXiv:1207.4867] which involves the derivation of oblique corrections in the MSSM at one-loop. In terms of the two-component spinor formalism, which is new in comparison with those used in the literature, the contributions arising from the fermion superpartners, i.e., neutralino-chargino sector to self-energy of Standard Model electroweak gauge bosons are calculated. Corresponding descendants the \(S\), \(T\) and \(U\) parameters are presented. The validity of our results is examined in two ways, which are then followed by detailed analysis on the results in the literature.
