Description
The student will join a physics measurement of the inclusive production of WbWb at the ATLAS experiment. The analysis is interesting as there are currently no models easily accessible to the LHC experiments that can accurately estimate this final state. The goal of the analysis is to measure various distributions in final states with one lepton as accurately as possible.
The student will learn the about the physics processes yielding WbWb — par top production and an associate production of the top quark with a W boson where one additional bottom quark is produced (tWb). Furthermore student will be involved in one of the analysis tasks. This will involve processing ATLAS data and simulation and making histograms, which the student will also learn how to interpret. Potential tasks include studies on usage of different simulated samples, different reconstruction algorithms and optimising methods to estimate non-prompt lepton backgrounds.
As an ATLAS analysis requires processing of large amounts of data, the expected composition is 50% physics, 50% working with analysis software (ROOT, C++, python).
