Joint HEP/Theory Seminar: Flavor Physics at Belle II

The Standard model of particle physics (SM) has been completed with
the observation of the Higgs boson in 2012. However, many questions
like the explanation for the large matter-antimatter asymmetry
observed in today's universe or the hierarchy problem remain
unanswered. The Belle II experiment at the SuperKEKB electron-positron
collider at KEK aims at providing new insights into these and other
questions by performing indirect searches for physics beyond the SM in
the flavor sector. It continues the successful work of the B-factories
around the turn of the millennium. Data-taking has started in spring
2019 and the plan is to collect the largest data set of B mesons with
an integrated luminosity of 50 ab^-1 by 2027. In the presentation the
current status of the Belle II experiment, the physics program of the
Belle II collaboration, and some first results of the early
data-taking will be presented. However, it will be a biased selection
based on my own contributions and interests.
