Exact form factors of the SU(N) Gross-Neveu model and 1/N expansion
Hrachya Babujian, Angela Foerster, Michael Karowski
The general SU(N) form factor formula is constructed. Exact form factors for the field, the energy momentum and the current operators are derived and compared with the 1/N-expansio…

Exact Pair Production Rate for a Smooth Potential Step
A. Chervyakov, H. Kleinert
We derive the exact rate of pair production of oppositely charged scalar particles by a smooth potential proportional to tanh kz in three dimensions. As a check we recover from thi…
