Complex Angular Momentum Diagonalization of the Bethe-Salpeter Structure in General Quantum Field Theory
J. Bros, G. A. Viano
The Complex Angular Momentum (CAM) representation of (scalar) four-point functions has been previously established starting from the general principles of local relativistic Quantu…

Reconstructing the thermal Green functions at real times from those at imaginary times
G. Cuniberti, E. De Micheli, G. A. Viano
By exploiting the analyticity and boundary value properties of the thermal Green functions that result from the KMS condition in both time and energy complex variables, we treat th…
