Standard model from a supergravity model with a naturally small cosmological constant
Abstract Guided by the naturalness criterion for an exponentially small cosmological constant, we present a string theory motivated 4-dimensional N $$ \mathcal{N} $$ = 1 non-linear supergravity model (or its linear version with a nilpotent superfield) with spontaneous supersymmetry breaking. The mod...
