Description

 

 

The aim of this workshop is to foster collaborations among researchers from the SAPHIR Millenium Institute in Chile with the local and international community on topics relevant to the institute's research lines. This year, the workshop's main topics will cover dark sectors and future collider/experiments, with focus on the recently approved Ship experiment at CERN, as well as the well motivated proposed Future Circular Collider FCC.
