International Workshop: Probing Fundamental Symmetries and Interactions with UCN

11 Apr 2016, 08:00 → 15 Apr 2016, 18:00 Europe/Berlin

JGU Mainz, Germany - Waldthausen Castle

The aim of this workshop is to bring together leading international experts from both experiment and theory in the field of UCN physics to discuss present and future experiments with UCN as well as progress in UCN sources and instrumentation.

The list of topics of our workshop comprises the full range of fundamental physics searches with UCN and also related fields of fundamental physics with cold neutrons. The workshop will include both invited and contributed talks.
