We represent free field construction of boundary states in Gepner models basing on the free field realization of N=2 superconformal minimal models. Using this construction we consider the open string spectrum between the boundary states and show that it can be described as Malikov, Schechtman, Vaintrob chiral de Rham complex of the LG orbifold. It allows to establish direct relation of the open string spectrum for boundary states in Gepner models to the open string spectrum for fractional… CONTINUE READING
