摘要

We present a systematic comparison of doubly charged Higgs boson production mechanisms at hadron colliders in the context of the type II seesaw model, emphasizing the importance of higher-order corrections and subdominant channels. We consider the Drell-Yan channel at next-to-leading order in QCD, photon fusion at leading order, gluon fusion with resummation of threshold logarithms up to next-to-next-to-next-to-leading logarithmic accuracy, and same-sign weak boson fusion at next-to-leading order in QCD. For the Drell-Yan process, we study the impact of a static jet veto at next-to-leading order matched to the resummation of jet veto scale logarithms at next-to-next-to-leading logarithmic accuracy. For the photon fusion channel, the dependence on modeling photon parton distribution functions is definitively assessed. To model vector boson fusion at next-to-leading order, we include all interfering topologies at O ( α 4 ) and propose a method for introducing generator-level cuts within the MC@NLO formalism. Our results are obtained using a Monte?Carlo tool chain linking the feynrules, nloct and madgraph5_amc@nlo programs and have necessitated the development of new, publicly available, Universal feynrules Output libraries that encode the interactions between the type II seesaw scalars and Standard Model particles. Libraries are compatible with both the normal and inverted ordering of Majorana neutrino masses.
