Production of Higgs boson excitations of universal extra dimension at the Large Hadron Collider

Abstract

The Kaluza-Klein excitations of the Higgs bosons of the universal extra dimension model are extremely challenging to detect. We discuss the production and possible detection mechanisms of such excited scalars at the LHC. The dominant production mechanism of such scalars is from the decay of the excited third generation quarks. In particular, the charged Higgs boson has a large production cross-section over most of the parameter space. We highlight how one may detect these excited scalars. We also comment on the production and detection of excited neutral scalars.

arXiv comment11 pages, 5 figures, the discussion on possible backgrounds has been considerably extended, some new references added, version to be published in PLB
