Resumen

Se presenta una búsqueda para la producción de un bosón de Higgs y uno o más quarks charm, en la que el bosón de Higgs se desintegra en un par de fotones. Esta búsqueda utiliza datos de colisiones protón-protón con una energía en el centro de masas de √s = 13 TeV y una luminosidad integrada de 140 fb−1 registrados por el detector ATLAS en el Gran Colisionador de Hadrones. El análisis se basa en la identificación de jets que contienen quarks charm y adopta un enfoque basado en la regresión del proceso gaussiano para modelar el fondo difotónico no resonante. El límite superior observado (esperado, asumiendo la señal del Modelo Estándar) en el nivel de confianza del 95% en la sección eficaz para la producción de un bosón de Higgs y al menos un jet que contiene quarks charm que pasa una selección fiducial es de 10,6 pb (8,8 pb). La sección transversal medida observada (esperada) para este proceso es 5,3 ± 3,2 pb (2,9 ± 3,1 pb).

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 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).",
