Search for the associated production of charm quarks and a Higgs boson decaying into a photon pair with the ATLAS detector ATLAS Collaboration
Abstract
A search for the production of a Higgs boson and one or more charm quarks, in
which the Higgs boson decays into a photon pair, is presented. This search uses proton-proton
collision data with a centre-of-mass energy of √
s = 13 TeV and an integrated luminosity
of 140 fb−1
recorded by the ATLAS detector at the Large Hadron Collider. The analysis
relies on the identifcation of charm-quark-containing jets, and adopts an approach based on
Gaussian process regression to model the non-resonant di-photon background. The observed
(expected, assuming the Standard Model signal) upper limit at the 95% confdence level
on the cross-section for producing a Higgs boson and at least one charm-quark-containing
jet that passes a fducial selection is found to be 10.6 pb (8.8 pb). The observed (expected)
measured cross-section for this process is 5.3 ± 3.2 pb (2.9 ± 3.1 pb).
