OVERVIEW
The major problems of modern fundamental physics, such as the problem of the origin of the inflaton, dark matter, and baryon numbers, all show the path to fundamental physics beyond standard cosmology. In this respect, the search for new particles opened up by the use of gravitational wave observations, in particular, the bosonic degrees of freedom represented by scalar fields, is very attractive. In this workshop we would like discuss broad topics related to the search for new physics and the exploration of new methods of testing theories using gravitational wave observations.
