Next-to-leading order contributions to the pole mass of gluino in minimal gauge mediation

Abstract

We compute the pole mass of the gluino in the minimal gauge mediation to two-loop order. The pole mass of the gluino begins to arise at one-loop order and the two-loop order correction shifts the leading order pole mass by 20% or even more. This shift is much larger than the expected accuracy of the mass determination at the LHC, and should be reckoned with for precision studies on the SUSY breaking parameters.Comment: 33 pages, 22 figures; contents improved including discussion on IR behavior, typos fixed, published versio
