Publisher: | Springer | 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 root s = 13TeV and an integrated luminosity of 140 fb(-1) recorded by the ATLAS detector at the Large Hadron Collider. The analysis relies on the identification 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% confidence level on the cross-section for producing a Higgs boson and at least one charm-quark-containing jet that passes a fiducial 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). | Description: | Meng, Lingxin/0000-0002-2901-6589; Elsing, Markus/0000-0002-1213-0545; Gwilliam, Carl/0000-0002-9401-5304; Borissov, Guennadi/0000-0002-4226-9521; Kartvelishvili, Vakhtang/0000-0002-1957-3787; Konstantinidis, Nikolaos/0000-0002-4140-6360; Ragusa, Francesco/0000-0002-4064-0489; Lewicki, Maciej Piotr/0000-0002-8972-3066; Ulloa Poblete, Pablo Augusto/0000-0002-0789-7581; Stanislaus, Beojan/0000-0001-9007-7658; Nasella, Laura/0000-0002-4871-784X; Redlinger, George/0000-0002-6437-9991; Mazzeo, Elena/0000-0002-8406-0195; Carbone, Antonio/0000-0002-4117-3800; D'Auria, Saverio/0000-0003-3393-6318; Carmignani, Joseph (Joe)/0000-0002-1705-1061; Volkotrub, Yuriy/0000-0002-3114-3798; Nasri, Salah/0000-0002-5985-4567; Muenstermann, Daniel/0000-0001-6223-2497 | URI: | https://doi.org/10.1007/JHEP02(2025)045 https://hdl.handle.net/20.500.11851/12502 |
