LHC prospects in searches for neutral scalars in pp ->gamma gamma plus jet

摘要

At hadron colliders, the gamma gamma + jet channel provides a larger signal-to-background ratio in comparison with the inclusive gamma gamma channel in hunting for scalars uncharged under the SM gauge group. By using NLO results for the SM Higgs boson production and corresponding background, we estimate LHC prospects in searches for the radion and sgoldstino in the gamma gamma + jet channel. Three-body final-state kinematics allows for refined cuts. We have found that this channel could be comparable with the gamma gamma channel in searches for new physics.
