Supersymmetric bag model as a new path to particle physics compatible to gravity

We show that large spin of particles does gravity strong, which shifts the usual Planck scale to effective action at the Compton distances. Considering Kerr's spinning particle with parameters of electron, we obtain a BPS solution for the core of spinning particle as a supersymmetric bag model, a gravitating analog of the known bag models. The shape of bag is deformed by spin to a disk which acquires a closed string and singular pole on the border of bag. The supersymmetric Kerr's bag model resolves the problem of compatibility gravity with quantum theory, forming a 4D analog of the D2-D1-D0-brane system of string–M-theory without extra dimensions and compactification.
