Currently I participate in the experiment ATLAS at CERN. My research interests are related to understanding the imbalance between matter and antimatter in the Universe. To explain this imbalance, the properties of particles and antiparticles must be different. This difference is called CP violation. I study CP violation using the particles containing b quark.
PhD Supervision Interests
Measurement of branching fraction of the semileptonic top quark decay to tauon. The Standard Model assumes the lepton flavour universality (LFU). Within this assumption, weak interaction of all leptons is exactly the same. However, the recent measurements of decays of B hadrons demonstrate an intriguing hint of deviation from LFU. The goal of this research is to test LFU in the semileptonic decay of the heaviest top quark to tauon and to measure the corresponding branching fraction with high precision. The statistics are collected by ATLAS experiment at CERN and is already available.
