We review the signal, and the $b\bar{b}$ background, for Higgs production by the exclusive double-diffractive process, $pp \to p+H+p$, and its subsequent $H \to b\bar{b}$ decay, at the LHC. We discuss the production of Higgs bosons in both…

In this work, we study the production of Higgs boson pairs at next-to-next-to-leading order in QCD matched to parton showers, using the \textsc{Geneva} framework and working in the heavy-top-limit approximation. This includes the…

Based on the analysis of 5 fb^-1 of data at the LHC, the ATLAS and CMS collaborations have presented evidence for a Higgs boson with a mass in the 125 GeV range. We consider the 125 GeV neutral Higgs pair production process in the context…
