NNLO QCD corrections to the resonant sneutrino/slepton production at Hadron Colliders

Understand

We present a complete next to next to leading order QCD corrections to the resonant sneutrino and charged slepton production cross sections at hadronic colliders such as the Tevatron and the Large Hadron Collider within the context of $R$-parity violating supersymmetric model.

• We have demonstrated the role of these corrections in reducing uncertainties resulting from renormalisation and factorisation scales and thereby making our predictions reliable.
• We have incorporated soft gluon effects at $N^3LO$ level in order to study the stability of our results under perturbation.
• The NNLO corrections are found to be large and significant.
