Abstract
A search for the standard model (SM) Higgs boson () produced with transverse momentum () greater than 450 GeV and decaying to a charm quark-antiquark () pair is presented. The search is performed using proton-proton collision data collected at by the CMS experiment at the LHC, corresponding to an integrated luminosity of 138 fb−1. Boosted 𝐻 →𝑐¯𝑐 decay products are reconstructed as a single large-radius jet and identified using a deep neural network charm tagging technique. The method is validated by measuring the 𝑍 →𝑐¯𝑐 decay process, which is observed in association with jets at high 𝑝𝑇 for the first time with a signal strength of 1.00+0.17−0.14(syst)±0.08(theo)±0.06(stat), defined as the ratio of the observed process rate to the SM expectation. The observed (expected) upper limit on 𝜎(𝐻)ℬ(𝐻→𝑐¯𝑐) is set at 47 (39) times the SM prediction at 95% confidence level.
