Regularization of superstring amplitudes and a cancellation of divergences in superstring theory
نویسنده
چکیده
For a calculation of divergent fermion string amplitudes a regularization procedure invariant under the supermodular group is constructed. By this procedure superstring amplitudes of an arbitrary genus are calculated using both partition functions and superfield vacuum correlators computed early. A finiteness of superstring amplitudes and related topics are discussed. E-mail address: [email protected]

Finiteness of multi-loop superstring amplitudes
Superstring amplitudes of an arbitrary genus are calculated through super-Schottky parameters by a summation over the fermion strings. For a calculation of divergent multiloop fermion string amplitudes a supermodular invariant regularization procedure is used. A cancellation of divergences in the superstring amplitudes is established. Grassmann variables are integrated, the superstring amplitud...
متن کاملLight-Cone Gauge Superstring Field Theory and Dimensional Regularization
We propose a dimensional regularization scheme in the light-cone gauge NSR superstring field theory to regularize the divergences caused by the colliding supercurrents inserted at the interaction points. We study the tree amplitudes and show that our scheme actually regularize the divergences. We examine the four-point amplitudes for the NS-NS closed strings and find that the results in the fir...
متن کاملSummability of Superstring Theory
Several arguments are given for the summability of the superstring perturbation series. Whereas the Schottky group coordinatization of moduli space may be used to provide refined estimates of large-order bosonic string amplitudes, the super-Schottky group variables define a measure for the supermoduli space integral which leads to upper bounds on superstring scattering amplitudes. The genus-dep...
متن کاملLight-cone gauge superstring field theory in linear dilaton background
The Feynman amplitudes of light-cone gauge superstring field theory suffer from various divergences. In order to regularize them, we study the theory in linear dilaton background Φ = −iQX with the number of spacetime dimensions fixed. We show that the theory with the Feynman iε (ε > 0) and Q > 10 yields finite results. e-mail: [email protected]
متن کاملUnimodular transformations of the supermanifolds and the calculation of the multi-loop amplitudes in the superstring theory
The modular transformations of the (1|1) complex supermanifolds in the likeSchottky modular parameterization are discussed. It is shown that these ”supermodular” transformations depend on the spinor structure of the (1|1) complex supermanifold by terms proportional to the odd modular parameters. The above terms are calculated in the explicit form. The discussed terms are important for the study...
