Research activity/Publications in the current year
(max characters 2500)
During my first year as a graduate student I worked in the field of String Theory and (Boundary) Conformal Field Theory.
I have been studying particular stringy scenarios involving D-branes intersecting at an angle in non factorized internal space as a way to model Yukawa couplings between fermions and bosons in String Theory. I have been mostly focussed on the classical instantonic contribution to the open string configuration with non abelian relative rotation of the branes, which corresponds to the classical contribution to the correlator of non abelian twist fields. The configuration is more general with respect to what it is possible to find in the literature where the internal space is factorized and the rotations are abelian: we showed that it is possible to find a solution by means of a sum of products of hypergeometric functions which reproduce the boundary conditions through their monodromy matrices. We were also able to prove that Yukawa couplings are more suppressed with respect to the factorized case and that it is possible to recover the abelian computation starting from the general procedure. A research paper on the subject is currently in preparation.
In the future we would like to extend this kind of observations to the closed string channel and consider the T-dual version of the intersecting D-branes, that is we want to consider boundary states on branes with a magnetic field on them.
