Description
Supersymmetry predicts a large number of scalar fields, some of which carry baryon and lepton numbers. I will discuss how fragmentation of scalar fields with an approximate U(1) symmetry into lumps is a general mechanism for primordial black hole formation. There are O(100) of such scalar fields (flat directions) in MSSM, which can naturally result in primordial black holes.
