DESCRIPTION:Heterotic orbifolds provide a simple\, globally consistent fra
 mework in which one can obtain the MSSM particle spectrum with no chiral e
 xotics from string theory. In order to understand the dynamical aspects an
 d phenomenology of these compactifications\, such as the decoupling of vec
 tor-like exotics\, moduli stabilization\, particle masses and couplings\, 
 we must compute the couplings in the corresponding low energy effective fi
 eld theory. \n\nWe study L-point string correlation functions and thus der
 ive string selection rules\, which determine the allowed couplings in the 
 superpotential of the low energy effective supergravity theory. \n\n
