Pair production of neutral Higgs particles in gluon-gluon collisions

摘要

Pair production processes of neutral Higgs particles will allow us to study the trilinear Higgs couplings at future high-energy colliders. Several mechanisms give rise to multi-Higgs final states in hadron interactions. In this paper, we investigate Higgs pair production in gluon-gluon collisions. After recapitulating pair production in the Standard Model, the analysis of the cross sections is carried out in detail for the neutral Higgs particles in the minimal supersymmetric extension. (orig.)
