This effective description includes the effective Yukawa couplings, and another logarithmic term which encodes the supersymmetry-breaking. We have performed 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.33 p.application/pdfeng(c) Società Italiana di Fisica & Springer Verlag, 2013Acceleradors de partículesPartícules (Física nuclear)Mètode de MontecarloSupersimetriaParticle acceleratorsParticles (Nuclear physics)Monte Carlo methodSupersymmetryEffective squark/chargino/neutralino couplings: MadGraph implementationinfo:eu-repo/semantics/article6225252013-06-21info:eu-repo/semantics/openAccess
