Description/Abstract

We study the process gg → b¯bH+H− at large tan β, 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 of
the 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 τ -lepton and missing energy”. While, for tan β 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.
