The flavor puzzle in multi-Higgs models
Andrew E. Blechman, Alexey A. Petrov, Gagik Yeghiyan
We reconsider the flavor problem in the models with two Higgs doublets. By studying two generation toy models, we look for flavor basis independent constraints on Yukawa couplings…
R-symmetric Gauge Mediation and the MRSSM
Andrew E. Blechman
This is an invited summary of a seminar talk given at various institutions in the United States and Canada. After a brief introduction, a review of the minimal R-symmetric supersym…
R-symmetric gauge mediation
Santiago De Lope Amigo, Andrew E. Blechman, Patrick J. Fox +1
We present a version of Gauge Mediated Supersymmetry Breaking which preserves an R-symmetry - the gauginos are Dirac particles, the A-terms are zero, and there are four Higgs doubl…
QCD Corrections to K-Kbar Mixing in R-symmetric Supersymmetric Models
Andrew E. Blechman, Siew-Phang Ng
The leading-log QCD corrections to K-Kbar mixing in R-symmetric supersymmetric models are computed using effective field theory techniques. The spectrum topology where the gluino i…
Probing the Randall-Sundrum geometric origin of flavor with lepton flavor violation
Kaustubh Agashe, Andrew E. Blechman, Frank Petriello
The ``anarchic'' Randall-Sundrum model of flavor is a low energy solution to both the electroweak hierarchy and flavor problems. Such models have a warped, compact extra dimension…
Shining on an Orbifold
Andrew E. Blechman
By shining a hypermultiplet from one side of the bulk of a flat five-dimensional orbifold, supersymmetry can be broken by boundary conditions. The extra dimension is stabilized in…
