Search for narrow Hγ resonances in proton-proton collisions at √s=13 TeV
A search for heavy, narrow resonances decaying to a Higgs boson and a photon (Hγ) has been performed in proton-proton collision data at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb−1 collected with the CMS detector at the LHC in 2016. Events containing a...

| Summary: | A search for heavy, narrow resonances decaying to a Higgs boson and a photon (Hγ) has been performed
in proton-proton collision data at a center-of-mass energy of 13 TeV, corresponding to an integrated
luminosity of 35.9 fb−1 collected with the CMS detector at the LHC in 2016. Events containing a photon
and a Lorentz-boosted hadronically decaying Higgs boson reconstructed as a single, large-radius jet are
considered, and the γ þ jet invariant mass spectrum is analyzed for the presence of narrow resonances. To
increase the sensitivity of the search, events are categorized depending on whether or not the large-radius jet
can be identified as a result of the merging of two jets originating from b quarks. Results in both categories
are found to agree with the predictions of the standard model. Upper limits on the production rate of Hγ
resonances are set as a function of their mass in the range of 720–3250 GeV, representing the most stringent
constraints to date |
