Abstract

Inclusive associated production of a light Higgs boson with one jet in $\mathrm{pp}$ collisions is studied in next-to-leading order quantum chromodynamics. Transverse momentum and rapidity distributions of the Higgs boson are calculated for the LHC in the large top-quark mass limit. We find that the $K$-factor of this process is large $(\ensuremath{\approx}1.6)$. Our result supports previous suggestions that the production channel $p+p\ensuremath{\rightarrow}H+\mathrm{jet}$ $\ensuremath{\rightarrow}\ensuremath{\gamma}+\ensuremath{\gamma}+\mathrm{jet}$ gives a measurable signal for Higgs production at the LHC in the mass range $100--140\mathrm{GeV}$.
