Eventos con un único leptón (e o µ) y al menos dos jets son seleccionados. Regiones de señal para todos los procesos son definidas con base al numero de jets y b jets. Las medidas, que se han hecho con dos métodos distintos, son comparadas con las predicciones del modelo standard, encontrando que son compatibles entre ellos.}, abstract = {ABSTRACT: The cross sections for the production of tt pairs, standard model Higgs boson, tt+bb, and the recently observed ttH process are measured using data collected in pp collisions at sqrt(s) = 13 TeV in 2017 by the CMS experiment at the LHC. Events with one lepton (e or µ) and at least two reconstructed jets in the final state are selected. Signal regions for all the signatures are defined based on the number of jets and b jets. The measurements, performed with two different approaches, are compared with the standard model expectations and they are found to be compatible.}, title = {Estudio de el Boson de Higgs y el quark Top usando eventos ttH}, author = {Kunnilan Muhammed Rafeek, Rufa}, }
