On Lorentz invariance and supersymmetry of four particle scattering amplitudes in S(N) R**8 orbifold sigma model
(American Physical Society, 1999)The SNR8 supersymmetric orbifold sigma model is expected to describe the Infrared limit of the matrix string theory. In the framework of the model the type IIA string interaction is governed by a vertex which was recently ... -
Virasoro amplitude from the S(N) R**24 orbifold sigma model
(Springer, 1998)Four tachyon scattering amplitude is derived from the SNR24 orbifold sigma model in the large N limit. The closed string interaction is described by a vertex which is a bosonic analog of the supersymmetric one, recently ...
