Studies on the four-tops production process with the ATLAS detector

  • 1. II. Physikalisches Institut, Georg-August-Universität Göttingen (Germany)

Description

The Large Hadron Collider (LHC) at CERN is a proton-proton collider that has provided, in the last three years, an exceptional integrated luminosity of about 80 fb1 at s = 13 TeV. This large dataset pushes the hosted experiment towards more and more challenging analyses, aimed at the measurement of ultra-rare processes. One of those is certainly the process of four top quarks production. The four-top production process, having a Standard Model (SM) cross-section of σtt¯tt¯ 9 fb, has a particular role in many Beyond-the-Standard-Model theories that predict particles much heavier than the top quark, which are then able to decay into a single or a pair of tops. A precise measurement of this cross-section represents not only a strong test for the SM predictions, but also an opportunity for the detection of new physics signals. A feature of this process is a strong hadronic environment, resulting in a large number of jets in the final state, many of which are b-jets. Consequently, this makes a precision measurement very challenging. In this talk an overview over the main features of the analysis as well as detailed discussions on the features of the process are given.
