Stable non-BPS D-branes of type I
M. Frau, L. Gallot, A. Lerda +1
We review the boundary state description of the non-BPS D-branes in the type I string theory and show that the only stable configurations are the D-particle and the D-instanton. We…
The field theory limit of multiloop string amplitudes
P. Di Vecchia, L. Magnea, R. Marotta +2
We report on recent progress in the use of string techniques for the computation of field theory amplitudes. We show how one-loop renormalization constants in Yang-Mills theory can…
The extended conformal theory of the Calogero-Sutherland model
R. Caracciolo, M. Frau, A. Lerda +2
We describe the recently introduced method of Algebraic Bosonization of (1+1)-dimensional fermionic systems by discussing the specific case of the Calogero-Sutherland model. A comp…
Renormalization constants from string theory
Paolo Di Vecchia, Alberto Lerda, Lorenzo Magnea +2
We review some recent results on the calculation of renormalization constants in Yang-Mills theory using open bosonic strings. The technology of string amplitudes, supplemented wit…
