Using of unitarity equations for the calculation of fermion interaction amplitudes in the superstring theory
G. S. Danilov
The unitarity equations for the boson interaction amplitudes in the superstring theory are used to calculate the interaction amplitudes including the Ramond states, which are 10-fe…
Manifest calculation and the finiteness of the superstring Feynman diagrams
G. S. Danilov
The multi-loop amplitudes for the closed, oriented superstring are represented by finite dimensional integrals of explicit functions calculated through the super-Schottky group par…
Finiteness of multi-loop superstring amplitudes
G. S. Danilov
Superstring amplitudes of an arbitrary genus are calculated through super-Schottky parameters by a summation over the fermion strings. For a calculation of divergent multi-loop fer…
Regularization of superstring amplitudes and a cancellation of divergences in superstring theory
G. S. Danilov
For a calculation of divergent fermion string amplitudes a regularization procedure invariant under the supermodular group is constructed. By this procedure superstring amplitudes…
Electromagnetic fields providing charge screening and confinement in two-dimensional massless electrodynamics
G. S. Danilov, I. T. Dyatlov, V. Yu. Petrov
The charge screening, confinement of fermion quantum numbers and the chiral condensate formation in two-dimensional QED is studied in details. It is shown that charge screening and…
Explicit Calculation of Multiloop Amplitudes in the Superstring Theory
G. S. Danilov
Multiloop superstring amplitudes are calculated in the explicit form by the solution of Ward identities. A naive generalization of Belavin-Knizhnik theorem to the superstring is fo…
