Using known formulae for form factors we sum up all their contributions and obtain a closed expression for a correlation function. This expression is a determinant of an integral operator. Similar determinant representations were proven to be useful not only in the theory of correlation functions, but also in the matrix models.21 pages, Latex, no figuresHigh Energy Physics - TheoryMathematical PhysicsExactly Solvable and Integrable Systemstext
