The Large Hadron Collider provides an unprecedented amount of proton-proton collisions which are used to probe the Standard Model of elementary particles. However, there is still no indication of new physics beyond the Standard Model (BSM). Therefore it is important to investigate also rare physics processes to search for BSM effects. The PhD student will exploit one such process - the production of four top quarks. This process probes the parameter space of many BSM theories such as the composite top quark models, Randall-Sundrum models, theories predicting new color-neutral particles,.... The PhD student will join the ATLAS experiment and he/she will get familiar with data analysis methods in high energy physics, including machine learning techniques.
