Higgs boson production in the U(1)B−L model at the ILC

Abstract

In the framework of the minimal [Formula: see text] extension of the Standard Model, we investigate the Higgs boson production processes [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text] at the International Linear Collider (ILC). We present the production cross-sections, the relative corrections and compare our results with the expected experimental accuracies for Higgs decay channel [Formula: see text]. In the allowed parameter space, we find that the effects of the three single Higgs boson production processes might approach the observable threshold of the ILC. But the Higgs signal strengths [Formula: see text] of the two double Higgs boson production processes are all out of the observable threshold so that these effects will be difficult to be observed at the ILC.
