Production and detection of the Higgs boson via heavy particles

Abstract

The cross section for neutral-Higgs-boson production in $\mathrm{pp}$ or $p\overline{p}$ collisions from Compton scattering ($\mathrm{gc}\to \mathrm{Hc}$) of gluons from charm quarks in the proton is estimated to be in the picobarn range. With $H\to \overline{c}c or \overline{\tau }\tau$ decay, the signature for this process is dramatic: The final state contains four fast charmed particles or two charmed particles in association with $\overline{\tau }\tau$ which are detectable through decay kinks or gaps. Comparisons are made with the fusion mechanism, which gives a comparable cross section but has much larger backgrounds.
