| Özet |
| A search for the standard model (SM) Higgs boson (H) produced with transverse momentum greater than 450 GeV and decaying to a charm quark-antiquark (cc) pair is presented. The search is performed using proton-proton collision data collected at√ s= 13 TeV by the CMS experiment at the LHC, corresponding to an integrated luminosity of 138 fb− 1. Boosted H→ cc 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→ cc 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 standard model expectation. The observed (expected) upper limit on σ (H) B (H→ cc) is set at 47 (39) times the SM prediction at 95% confidence level. |
