One-loop Yukawas on Intersecting Branes
S. A. Abel, B. W. Schofield
We calculate Yukawa interactions at one-loop on intersecting D6 branes. We demonstrate the non-renormalization theorem in supersymmetric configurations, and show how Yukawa beta fu…

Brane-Antibrane Kinetic Mixing, Millicharged Particles and SUSY Breaking
Steven Abel, Ben Schofield
It is known that hidden U(1) gauge factors can couple to visible U(1)'s through Kinetic Mixing. This phenomenon is shown generically to occur in nonsupersymmetric string set-ups, b…
