$W^+W^-$ production in Large extra dimension model at next-to-leading order in QCD at the LHC

Understand

We present next-to-leading order QCD corrections to production of two $W$ bosons in hadronic collisions in the extra dimension ADD model.

• Various kinematical distributions are obtained to order $\alpha_s$ in QCD by taking into account all the parton level subprocesses.
• We estimate the impact of the QCD corrections on various observables and find that they are significant.
• We also show the reduction in factorization scale uncertainty when ${\cal O}(\alpha_s)$ effects are included.
