Description
A search for the Standard Model Higgs boson produced in association with a high-energy photon is performed using ${132}$ ${fb^{-1}}$ of $pp$ collision data at $\sqrt{s}={13}$ TeV collected with the ATLAS detector at the Large Hadron Collider. The vector boson fusion production mode of the Higgs boson is particularly powerful for studying the $H(\rightarrow b \bar{b})\gamma$ final state because the photon requirement greatly reduces the multijet background and because the Higgs boson decays primarily to bottom quark-antiquark pairs. Utilization of Monte Carlo, machine learning, and model fitting techniques resulted in a measured Higgs boson signal strength of $1.3 \pm 1.0$ relative to the Standard Model prediction. This correlates with an observed signal significance greater than background of 1.3 standard deviations, compared to 1.0 standard deviations expected.
