Yukawa Hierarchies from Split Fermions in Extra Dimensions

Eugene A. Mirabelli, Martin Schmaltz

We explore a mechanism for generating the Yukawa hierarchies by displacing the left- and right-handed components of the Standard Model fermions in a higher-dimensional space. We fi…

Hadronic Effects in Two-Body B decays

Helen Quinn

In these lectures I discuss the impact of soft hadronic physics on predictions for B decays. Unfortunately our tools for calculating these effects are limited; even after the use o…

Impact of D0-D0bar mixing on the experimental determination of gamma

Joao P Silva, Abner Soffer

Several methods have been devised to measure the weak phase gamma using decays of the type B+- --> D K+-, where it is assumed that there is no mixing in the D0-D0bar system. Howeve…

The Precision Monte Carlo Event Generator KK For Two-Fermion Final States In e+e- Collisions

S. Jadach, B. F. L. Ward, Z. Was

We present the Monte Carlo event generator KK version 4.13 for precision predictions of the Electroweak Standard Model for the process , a…

Manyfold Universe

Nima Arkani-Hamed, Savas Dimopoulos, Gia Dvali +1

We propose that our world is a brane folded many times inside the sub-millimeter extra dimensions. The folding produces many connected parallel branes or folds with identical micro…

Supersymmetry Breaking through Transparent Extra Dimensions

D. Elazzar Kaplan, Graham D. Kribs, Martin Schmaltz

We propose a new framework for mediating supersymmetry breaking through an extra dimension. It predicts positive scalar masses and solves the supersymmetric flavor problem. Supersy…
