Belavin's (Z/nZ)-symmetric model is considered on the
basis of bosonization of vertex operators in the An−1(1)​ model and
vertex-face transformation. Free field representations of nonlocal tail
operators are constructed for off diagonal matrix elements with respect to the
ground state sectors. As a result, integral formulae for form factors of any
local operators in the (Z/nZ)-symmetric model can be
obtained, in principle.Comment: 24 pages, 4 figures, published in J. Phys. A: Math. Theor. 43 (2010)
