Abstract
Numerous new physics theories suggest the presence of novel scalar particles, sgluons, lying in the adjoint representation of the QCD gauge group. Since these new fields are expected to decay into colored Standard Model (SM) particles, in particular into one or two top quarks, these theories predict a potential increase of the hadroproduction rate associated with multitop final states.
We present a study on the production of sgluons in proton-proton collisions, with the ATLAS detector at the Large Hadron Collider (LHC). We investigate four-top events, which are very rare in SM, to probe the possible existence of sgluons. By analyzing Monte Carlo simulations and data from LHC Run 2 (with a center-of-mass energy of 13 TeV) and Run 3 (13.6 TeV), we aim to discover the signals of sgluons or set limits on the production cross section versus mass.
This presentation will focus on the generation, validation, and preprocessing of Monte Carlo simulation samples and their comparison with data from the collider. Additionally, the lecture will provide an overview of the ATLAS’s workflow and the analytical methods employed in the study.
Anyone interested is welcome to attend.
