| Popis: | We study the pair production of charged Higgs bosons at the CERN Large Hadron Collider in the context of the minimal supersymmetric extension of the standard model. We compare the contributions due to qq-bar annihilation at the tree level and gg fusion, which proceeds at one loop. At small or large values of tan(beta), H^+H^- production proceeds dominantly via bb-bar annihilation, due to Feynman diagrams involving neutral CP-even Higgs bosons and top quarks, which come in addition to the usually considered Drell-Yan diagrams. In the case of gg fusion, the squark loop contributions may considerably enhance the well-known quark loop contributions. Comment: 15 pages (Latex), 4 figures (Postscript) |
