New Perspective on Galaxy Clustering as a Cosmological Probe: General Relativistic Effects
Jaiyul Yoo, A. Liam Fitzpatrick, Matias Zaldarriaga
We present a general relativistic description of galaxy clustering in a FLRW universe. The observed redshift and position of galaxies are affected by the matter fluctuations and th…
(Extra)Ordinary Gauge Mediation
Clifford Cheung, A. Liam Fitzpatrick, David Shih
We study models of "(extra)ordinary gauge mediation," which consist of taking ordinary gauge mediation and extending the messenger superpotential to include all renormalizable coup…
Sequestering CP Violation and GIM-Violation with Warped Extra Dimensions
Clifford Cheung, A. Liam Fitzpatrick, Lisa Randall
We propose a model of spontaneous CP violation to address the strong CP problem in warped extra dimensions that relies on sequestering flavor and CP violation. We assume that brane…
Flavor from Minimal Flavor Violation & a Viable Randall-Sundrum Model
A. Liam Fitzpatrick, Gilad Perez, Lisa Randall
We present a variant of the warped extra dimension, Randall-Sundrum (RS), framework which is based on five dimensional (5D) minimal flavor violation (MFV), in which the only source…
On the consistency relation of the 3-point function in single field inflation
Clifford Cheung, A. Liam Fitzpatrick, Jared Kaplan +1
The consistency relation for the 3-point function of the CMB is a very powerful observational signature which is believed to be true for every inflationary model in which there is…
The Effective Field Theory of Inflation
Clifford Cheung, Paolo Creminelli, A. Liam Fitzpatrick +2
We study the effective field theory of inflation, i.e. the most general theory describing the fluctuations around a quasi de Sitter background, in the case of single field models.…
