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.
