On the two-loop O({alpha}{sub s}{sup 2}) corrections to the pole mass of the t quark in the MSSM

Journal Article · · Physics of Atomic Nuclei
The paper is devoted to the calculation of two-loop O({alpha}{sub s}{sup 2}) MSSM corrections to the relation between the pole mass of the t quark and its running mass in the DR-bar scheme. Firstly, the value of the second-order contribution from large-mass expansion in mt/M{sub SUSY} is studied. Contrary to our expectations, this contribution turned out to be negligible. As a by-product of this calculation, the two-loop anomalous dimension of the running quark DR-bar mass is obtained in the supersymmetric QCD. Secondly, the influence of the two-loop corrections to the t-quark mass on the predicted superpartner masses is investigated.
