Kaehler Metrics: String vs Field Theoretical Approach
P. Di Vecchia, A. Liccardo, R. Marotta +1
We use both a string and a field theoretical approach in order to determine respectively the Kaehler metrics of untwisted and twisted open strings attached to magnetized D9 branes…
Kaehler Metrics and Yukawa Couplings in Magnetized Brane Models
P. Di Vecchia, A. Liccardo, R. Marotta +1
Using the field theoretical approach introduced by Cremades, Ibanez and Marchesano for describing open strings attached to D9 branes having different magnetizations, we give a proc…
Wrapped Magnetized Branes: Two Alternative Descriptions?
P. Di Vecchia, A. Liccardo, R. Marotta +2
We discuss two inequivalent ways for describing magnetized D-branes wrapped N times on a torus T^2. The first one is based on a non-abelian gauge bundle U(N), while the second one…
Instanton effects in N=1 brane models and the Kahler metric of twisted matter
Marco Billo, Paolo Di Vecchia, Marialuisa Frau +3
We consider locally consistent systems of magnetized D9 branes on an orbifolded six-torus which support N=1 gauge theories. In such realizations, the matter multiplets arise from "…
Instantons in N=2 magnetized D-brane worlds
Marco Billo, Marialuisa Frau, Igor Pesando +3
In a toroidal orbifold of type IIB string theory we study instanton effects in N=2 super Yang-Mills theories engineered with systems of wrapped magnetized D9 branes and Euclidean D…
