Welcome to SOM’s documentation webpage!

SOM (We are) is one of the leading theoretical particle physics groups in Spain, composed of members from the Institute of Corpuscular Physics (IFIC) at the University of Valencia and the Spanish National Research Council (CSIC). Our team is formed by 13 senior researchers, as well as a large number of postdoctoral fellows and PhD students, all dedicated to cutting-edge research in the field of theoretical particle physics.
