CP Violation and Flavor SU(3) Breaking in D-meson Decays
David Pirtskhalava, Patipan Uttayarat
We carry out a systematic flavor SU(3) analysis of D-meson decays including the leading order symmetry breaking effects. We find that SU(3) breaking can easily account for the rece…
Explaining the ttbar Forward-Backward Asymmetry from a GUT-Inspired Model
David C. Stone, Patipan Uttayarat
We consider a model that includes light colored scalars from the {\bf 45} and {\bf 50} representations of SU(5) in order to explain the CDF- and D-reported forward-ba…
A Very Light Dilaton
Benjamín Grinstein, Patipan Uttayarat
We present a completely perturbative model that displays behavior similar to that of walking technicolor. In one phase of the model RG-trajectories run towards an IR-fixed point bu…
Hidden Fine Tuning In The Quark Sector Of Little Higgs Models
Benjamin Grinstein, Randall Kelley, Patipan Uttayarat
In Little Higgs models a collective symmetry prevents the higgs from acquiring a quadratically divergent mass at one loop. We have previously shown that the couplings in the Little…
