摘要: Abstract We study the constraints imposed by flabour changing neutral current phenomena on supersymmetrizations of standard model where a non-flat Kahler metric and/or new superfields are present. In particular, we consider SU(5), SO(10) and E6 grand unified extensions. find that present experimental bounds μ → e + γ, b s γ results concerning K − B d mixings severely constrain choice spontaneously broken N = 1 supergravity theories whose low energy limit yields model.
