We calculate the pole mass of the gluino as a function of the running parameters in the lagrangian, to O(alpha_s^2) in SUSY QCD. The correction shifts the pole mass from the running mass by typically 1-2 %. This shift can be larger than the…
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.…
