Higgsless Electroweak Symmetry Breaking
Csaba Csaki
We discuss the possibility of breaking the electroweak symmetry in theories with extra dimensions via boundary conditions, without a physical Higgs scalar in the spectrum. In these…
Exorcising w < -1
Csaba Csaki, Nemanja Kaloper, John Terning
We show that the combined dimming of Type Ia supernovae induced by both a cosmological constant and the conversion of photons into axions in extra-galactic magnetic fields can impe…
Curing the Ills of Higgsless Models: the S Parameter and Unitarity
Giacomo Cacciapaglia, Csaba Csaki, Christophe Grojean +1
We consider various constraints on Higgsless models of electroweak symmetry breaking based on a bulk SU(2)_L x SU(2)_R x U(1)_{B-L} gauge group in warped space. First we show that…
TASI Lectures on Extra Dimensions and Branes
Csaba Csaki
This is a pedagogical introduction into theories with branes and extra dimensions. We first discuss the construction of such models from an effective field theory point of view, an…
A Mixed Phase of SUSY Gauge Theories from a-Maximization
Csaba Csaki, Patrick Meade, John Terning
We study N=1 supersymmetric SU(N) gauge theories with an antisymmetric tensor and F flavors using the recent proposal of a-maximization by Intriligator and Wecht. This theory had p…
Oblique Corrections from Higgsless Models in Warped Space
Giacomo Cacciapaglia, Csaba Csaki, Christophe Grojean +1
We calculate the tree-level oblique corrections to electroweak precision observables generated in higgless models of electroweak symmetry breaking with a 5D SU(2)_L x SU(2)_R x U(1…
