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…
(Pseudo)-Dirac neutrinos and leptogenesis
Steven Abel, Veronique Page
We discuss how Dirac neutrinos can naturally be generated in supersymmetry and how they allow for an Affleck-Dine leptogenesis scenario, in which a left-right asymmetry is generate…
Illuminating the Hidden Sector of String Theory by Shining Light through a Magnetic Field
Steven A. Abel, Joerg Jaeckel, Valentin V. Khoze +1
Many models of physics beyond the Standard Model predict minicharged particles to which current and near future low-energy experiments are highly sensitive. Such minicharges arise…
Vacuum Birefringence as a Probe of Planck Scale Noncommutativity
Steven A. Abel, Joerg Jaeckel, Valentin V. Khoze +1
Because of ultraviolet/infrared (UV/IR) mixing, the low energy physics of noncommutative gauge theories in the Moyal-Weyl approach seems to depend crucially on the details of the u…
