Description

We calculate the trilinear superpotential of the hidden sector of the three generation flipped SU(5)xU(1)xU(1)4xSO(10)xSU(4) superstring model. We perform a renormalization group analysis of the model taking into account the hidden sector. We find that, in all relevant cases, fractionally charged tetraplets of the hidden SO(6) gauge group are confined at a high scale. Nevertheless, their contribution to the observable U(1) gauge coupling evolution results in a drastic reduction of the available freedom in the values of a3(mw), sin2θw and Mx that allow superunification.
