Abstract:
The one and two-particle form factors of the energy operator in the two-dimensional Ising model in a magnetic field at T=TcT=T_c are exactly computed within the form factor bootstrap approach. Together with the matrix elements of the magnetisation operator already computed in ref.\,\cite{immf}, they are used to write down the large distance expansion for the correlators of the two relevant fields of the model.
