Realistic Yukawa Couplings through Instantons in Intersecting Brane Worlds
Steven A. Abel, Mark D. Goodsell
The Yukawa couplings of the simpler models of D-branes on toroidal orientifolds suffer from the so-called ``rank one'' problem -- there is only a single non-zero mass and no mixing…
Why the early Universe preferred the non-supersymmetric vacuum: Part II
Steven A. Abel, Joerg Jaeckel, Valentin V. Khoze
It was recently shown in hep-th/0610334 that in the context of the ISS models with a metastable supersymmetry breaking vacuum, thermal effects generically drive the Universe to the…
SUSY breaking by a metastable ground state: Why the early Universe preferred the non-supersymmetric vacuum
Steven A. Abel, Chong-Sun Chu, Joerg Jaeckel +1
Supersymmetry breaking in a metastable vacuum is re-examined in a cosmological context. It is shown that thermal effects generically drive the Universe to the metastable minimum ev…
Noncommutativity from the string perspective: modification of gravity at a mm without mm sized extra dimensions
Steven Abel, Chong-Sun Chu, Mark Goodsell
We explore how the IR pathologies of noncommutative field theory are resolved when the theory is realized as open strings in background B-fields: essentially, since the IR singular…
Intersecting Brane Worlds at One Loop
Steven A. Abel, Mark D. Goodsell
We develop techniques for one-loop diagrams on intersecting branes. The one-loop propagator of chiral intersection states on D6 branes is calculated exactly and its finiteness is s…
