Topcolor in the LHC Era
Elizabeth H. Simmons, R. Sekhar Chivukula, Baradhwaj Coleppa +2
Ongoing LHC searches for the standard model Higgs Boson in WW or ZZ decay modes strongly constrain the top-Higgs state predicted in many models with new dynamics that preferentiall…
Production of Massive Color-Octet Vector Bosons at Next-to-Leading Order
R. Sekhar Chivukula, Arsham Farzinnia, Roshan Foadi +1
We report the first complete calculation of QCD corrections to the production of a massive color-octet vector boson. Our next-to-leading-order (NLO) calculation includes both virtu…
Technipion Limits from LHC Higgs Searches
R. Sekhar Chivukula, Pawin Ittisamai, Jing Ren +1
LHC searches for the standard model Higgs Boson in di-photon or di-tau decay modes place strong constraints on the light top-pion state predicted in technicolor models that include…
LHC Limits on the Top-Higgs in Models with Strong Top-Quark Dynamics
R. Sekhar Chivukula, Baradhwaj Coleppa, Heather E. Logan +2
LHC searches for the standard model Higgs Boson in WW or ZZ decay modes place strong constraints on the top-Higgs state predicted in many models with new dynamics preferentially af…
The Flavor Structure of the Three-Site Higgsless Model
Tomohiro Abe, R. Sekhar Chivukula, Elizabeth H. Simmons +1
We study the flavor structure of the three-site Higgsless model and evaluate the constraints on the model arising from flavor physics. We find that current data constrain the model…
Simplified Models for LHC New Physics Searches
Daniele Alves, Nima Arkani-Hamed, Sanjay Arora +92
This document proposes a collection of simplified models relevant to the design of new-physics searches at the LHC and the characterization of their results. Both ATLAS and CMS hav…
Patterns of Custodial Isospin Violation from a Composite Top
R. Sekhar Chivukula, Roshan Foadi, Elizabeth H. Simmons
In this paper we consider the effects of top quark compositeness on the electroweak parameters T-hat and S-hat and the Zbb coupling. We do so by using an effective field theory ana…
Top-Higgs and Top-pion phenomenology in the Top Triangle Moose model
R. Sekhar Chivukula, Baradhwaj Coleppa, Heather E. Logan +2
We discuss the deconstructed version of a topcolor-assisted technicolor model wherein the mechanism of top quark mass generation is separated from the rest of electroweak symmetry…
