NNLO QCD corrections to the resonant sneutrino/slepton production at hadron colliders

We present a complete next to next to leading order QCD corrections to the resonant production of sneutrino and charged slepton at the Tevatron and the Large Hadron Collider within the context of R-parity violating supersymmetric model. We have demonstrated the role of NNLO QCD corrections in reducing uncertainties resulting from renormalisation and factorisation scales and thereby making our predictions reliable. We have incorporated soft gluon effects at N3LO level in order to study the stability of our results under perturbation. The results obtained in this article are also applicable to resonance production of any color-neutral scalar coupled to fermions through Yukawa interaction.
