Flavour physics: from Belle to Belle II

Belle is one of the most successful experiments in particle physics; together with BaBar it dominated experimental flavour physics for more than a decade. Its results have to a large degree shaped our present understanding of flavour physics, and have decisevely contributed to the 2008 Nobel prize for M. Kobayashi and T. Maskawa. Its successor, Belle II at the new SuperKEKB accelerator is under preparation, expected to start data taking in 2018. The talk will cover highlights of the Belle experiment, the preparation of Belle II, and prospects for the future.

The speaker

Peter Križan got his Diploma in Physics at the University of Ljubljana in 1980 with a thesis done in theoretical surface physics. He finished his Ph. D. at the University of Ljubljana in 1987 in experimental particle physics participating in the SC94 experiment at CERN. Then he was at DESY in Hamburg, until 1992 member of the ARGUS experiment and HERA-B experiment from 1992 - 2001. In 2001 he became a member of the BELLE experiment, and since 2008 also of BELLE II. Since 2002 he has a full professorship at the University of Ljubljana at the Faculty for Mathematics and Physics, and from 2003-2005 he was the head of physics department and vice dean. Furthermore, he is a senior research associate at the J. Stefan Institute in Ljubljana, Slovenia. Peter Križan had important positions in the experiments and its boards he participated, e.g. 2008-2009 he was the chair of the Belle II Steering Committee and technical coordinator, and 2009-2013 spokesperson of the Belle II Collaboration. He has been member and chair of several committees. Among them he is member of the Scientific Advisory Boards of the HEPHY and the Stefan Meyer Institute in Vienna since 2014. He is editor of the journal Nuclear Instruments and Methods A since 2010 and member of the editorial board of Journal of Instrumentation (JINST) since 2006 and was its assistant director in 2007-2008. In 2002 he got the Zois distinction and in 2008 he got the Zois award (Slovenian state award for science). He teaches various courses at the University of Ljubljana and was lecturer in numerous national and international schools in different countries.
