Abstract:
Belle II detector in Japan belongs to the next generation of B factories, experiments primarily dedicated to explore properties of B mesons, particles containing b-quark. The goal of Belle II is to take a 100 times bigger dataset than its predecessor. We are far from that yet - current integrated luminosity of Belle II is half of the Belle one.
Thanks to the better detector resolution, even with this smaller dataset Belle II has already published several world-leading results, not only related to B mesons. One of them is the most precise determination of the tau lepton mass - one of the fundamental parameters of the Standard Model.
In the seminar, I will introduce methods used for measuring tau lepton mass at various experiments with a focus on the new Belle II result.
The seminar will be held in the conference hall in the main building of the Institute of Physics, Na Slovance 2, Prague 8 on the ground floor.
