Análisis simplificado de procesos de alta energía con datos abiertos del compact muon solenoid (cms) : estudio de la producción de cuatro quarks top a través del canal electrón+jets, en colisiones protón-protón, utilizando datos abiertos del experimento cms correspondientes a 2.3 fb⁻¹ de luminosidad integrada y energía de centro de masa √s = 13 TeV.

Abstract

A simplified analysis on the search of the production of four top quarks (t ̄tt ̄t) in a single lepton channel, electron+jets, is presented. The objective is to replicate the results as faithfully as possible compared to the original publication by using the Python programming language. This analysis uses Open Data produced by the CMS experiment which corresponds to 2.3 fb⁻¹ of integrated luminosity with √s = 13 TeV. To distinguish between signal and background, first the baseline event selection filters are applied. Then, an agreement between experimental data and Monte Carlo simulations is showed. Next, in order to improve the perfomance in distinguishing background (i.e. t ̄t, tW, W+jets) and signal (t ̄tt ̄t), a Boosted Decision Tree algorithm has been applied.
