Resumen

Este informe revisa los resultados publicados de las búsquedas de posibles partículas escalares adicionales y desintegraciones exóticas del bosón de Higgs realizadas por la Colaboración ATLAS utilizando hasta 140 fb−1 de datos de colisiones protón-protón de 13 TeV recopilados durante la Ejecución 2 del Gran Colisionador de Hadrones. Se examinan los resultados clave y se señalan los excesos observados, aunque nunca estadísticamente convincentes. Se imponen restricciones a los parámetros de varios modelos que extienden el Modelo Estándar, por ejemplo, añadiendo uno o más campos singlete o doblete, u ofreciendo canales exóticos de desintegración del bosón de Higgs. Se discuten resúmenes de nuevas búsquedas, así como extensiones de búsquedas previas. Estos nuevos resultados tienen un alcance más amplio o alcanzan límites de exclusión más estrictos. Se destacan las nuevas técnicas experimentales desarrolladas para estas búsquedas. También se enumeran los canales de búsqueda que aún no se han examinado, ya que brindan información sobre posibles áreas futuras de exploración.

abstract = "This report reviews the published results of searches for possible additional scalar particles and exotic decays of the Higgs boson performed by the ATLAS Collaboration using up to 140 fb−1 of 13 TeV proton–proton collision data collected during Run 2 of the Large Hadron Collider. Key results are examined, and observed excesses, while never statistically compelling, are noted. Constraints are placed on parameters of several models which extend the Standard Model, for example by adding one or more singlet or doublet fields, or offering exotic Higgs boson decay channels. Summaries of new searches as well as extensions of previous searches are discussed. These new results have a wider reach or attain stronger exclusion limits. New experimental techniques that were developed for these searches are highlighted. Search channels which have not yet been examined are also listed, as these provide insight into possible future areas of exploration.",
