Yukawa Couplings involving Excited Twisted Sector States for ${\mathbf{Z}}_M\times {\mathbf{Z}}_N$ Orbifolds

Abstract

A study is made for ${\mathbf{Z}}_M\times {\mathbf{Z}}_N$ orbifolds of the modification of the form of the twisted sector Yukawa couplings when some of the states involved are excited twisted sectors rather than twisted sector ground states.
