Next-to-leading order QCD effects in associated charged Higgs and W boson production in the MSSM at the CERN Large Hadron Collider
- Department of Physics, Peking University, Beijing 100871 (China)
We present the calculations of the next-to-leading order (NLO) QCD corrections to the inclusive total cross sections for the associated production of the W{sup {+-}}H{sup {+-}} through bb annihilation in the minimal supersymmetric standard model at the CERN Large Hadron Collider. The NLO QCD corrections can either enhance or reduce the total cross sections, but they generally efficiently reduce the dependence of the total cross sections on the renormalization/factorization scale. The magnitude of the NLO QCD corrections is about 10% in most of the parameter space and can reach 15% in some parameter regions. We also show the Monte Carlo simulation results for the 2j+{tau}{sub jet}+pe{sub T} signature from the W{sup {+-}} and the H{sup {+-}} decays including the NLO QCD effects, and find an observable signal at a 5{sigma} level in some parameter region of the minimal supergravity model.
