Pair production of charged Higgs bosons in association with bottom quark pairs at the Large Hadron Collider
Pair production of charged Higgs bosons in association with bottom quark pairs at the Large Hadron Collider
We study the process gg ? b¯bH+H? at large tan ?, where it represents the dominant production mode of charged Higgs boson pairs in a Type II 2-Higgs doublet model, including the minimal supersymmetric standard model. The ability to select this signal would in principle enable the measurements of some triple-Higgs couplings, which in turn would help understanding the structure ofthe extended Higgs sector. We outline a selection procedure that should aid in disentangling the Higgs signal from the main irreducible background. This exploits a signature made up by “four b-quark jets, two light-quark jets, a ? -lepton and missing energy”. While, for tan ? 30 and over a significant MH± range above the top mass, a small signal emerges already at the Large Hadron Collider after 100 fb?1, ten times as much luminosity would be needed to perform accurate measurements of Higgs parameters in the above final state, rendering this channel a primary candidate to benefit from the so-called “Super” Large Hadron Collider option, for which a tenfold increase in instantaneous luminosity is currently being considered.

Abstract
We study the process gg ? b¯bH+H? at large tan ?, where it represents the dominant production mode of charged Higgs boson pairs in a Type II 2-Higgs doublet model, including the minimal supersymmetric standard model. The ability to select this signal would in principle enable the measurements of some triple-Higgs couplings, which in turn would help understanding the structure ofthe extended Higgs sector. We outline a selection procedure that should aid in disentangling the Higgs signal from the main irreducible background. This exploits a signature made up by “four b-quark jets, two light-quark jets, a ? -lepton and missing energy”. While, for tan ? 30 and over a significant MH± range above the top mass, a small signal emerges already at the Large Hadron Collider after 100 fb?1, ten times as much luminosity would be needed to perform accurate measurements of Higgs parameters in the above final state, rendering this channel a primary candidate to benefit from the so-called “Super” Large Hadron Collider option, for which a tenfold increase in instantaneous luminosity is currently being considered.
