ΔMK and εK in SUSY at the next-to-leading order

We perform a Next-to-Leading order analysis of ΔS = 2 processes beyond the Standard Model. Combining the recently computed NLO anomalous dimensions and the B parameters of the most general ΔS = 2 effective Hamiltonian, we give an analytic formula for ΔMK and εK in terms of the Wilson coefficients at the high energy scale. This expression can be used for any extension of the Standard Model with new heavy particles. Using this result, we consider gluino-mediated contributions to ΔS = 2 transitions in general SUSY models and provide an improved analysis of the constraints on off-diagonal mass terms between the first two generations of down-type squarks. Finally, we improve the constraints on R-violating couplings from ΔMK and εK-.
