Enhancement of associated H^\pm W^\mp production in the NMSSM

Understand

We study the associated production of a charged Higgs and a W boson in high-energy pp collisions at the Large Hadron Collider.

• This is an interesting process for charged Higgs discovery, or exclusion, since the production cross section could depend strongly on the model, offering potential discriminating power between supersymmetric extensions of the Standard Model with minimal or extended Higgs sectors.
• We compute the cross section for this process in the next-to-minimal supersymmetric Standard Model (NMSSM), at the tree level for quark-quark scattering and at one-loop level for gluon-gluon scattering.
• The most important corrections beyond leading order are taken into account using an improved Born approximation.
