Title: Potential for measuring the H{sup {+-}}W{sup {+-}}Z{sup 0} vertex from WZ fusion at the CERN Large Hadron Collider

Abstract

We investigate the possibility of measuring the H{sup {+-}}W{sup {+-}}Z{sup 0} vertex from the single H{sup {+-}} production process via WZ fusion at the CERN Large Hadron Collider (LHC). This vertex strongly depends on the structure of the Higgs sector in various new physics scenarios, so that its measurement can be useful to distinguish the models. A signal and background simulation under the expected detector performance at the LHC is done for the processes of pp{yields}W{sup {+-}}Z{sup 0}X{yields}H{sup {+-}}X{yields}tbX and pp{yields}W{sup {+-}}Z{sup 0}X{yields}H{sup {+-}}X{yields}W{sup {+-}}Z{sup 0}X, and the required magnitudes of the H{sup {+-}}W{sup {+-}}Z{sup 0} vertex for observation are evaluated. It is found that although the loop-induced H{sup {+-}}W{sup {+-}}Z{sup 0} vertex in multi-Higgs doublet models cannot be measurable, the latter process can be useful to test the model with a real and a complex triplets.
