Effective squark/chargino/neutralino couplings: MadGraph implementation    [PDF]

Arian Abrahantes, Jaume Guasch, Siannah Penaranda, Raul Sanchez-Florit
We have included the effective description of squark interactions with charginos/neutralinos in the MadGraph MSSM model. This effective description includes the effective Yukawa couplings, and another logarithmic term which encodes the supersymmetry-breaking. We provide an extensive test of our implementation analyzing the results of the partial decay widths of squarks into charginos and neutralinos obtained by using FeynArts/FormCalc programs and the new model file in MadGraph. We present results for the cross-section of top-squark production decaying into charginos and neutralinos.
