Expectation values of descendent fields in the Bullough-Dodd model and related perturbed conformal field theories

P. Baseilhac, M. Stanishkov

The exact vacuum expectation values of the second level descendent fields $<(\partial \varphi {)}^2(\overline{\partial }\varphi {)}^2{e}^{a\varphi }>$ in the Bullough-Dodd model are calculated. By performing q…
