A Composite Twin Higgs Model (2008)
Twin Higgs models are economical extensions of the Standard Model that stabilize the electroweak scale. In these theories the Higgs field is a pseudo Nambu-Goldstone boson that is protected against...
The Supersymmetric Higgs (2008)
Batra, Puneet, Ponton, Eduardo
In the Minimal Supersymmetric Standard Model (the MSSM), the electroweak symmetry is restored as supersymmetry-breaking terms are turned off. We describe a generic extension of the MSSM where the...
Pseudo-redundant vacuum energy (2008)
Batra, Puneet, Hinterbichler, Kurt, Hui, Lam, Kabat, Daniel
We discuss models that can account for today's dark energy. The underlying cosmological constant may be Planck scale but starts as a redundant coupling which can be eliminated by a field...
Symmetry Breaking Patterns for the Little Higgs from Strong Dynamics (2007)
We show how the symmetry breaking pattern of the simplest little Higgs model, and that of the smallest moose model that incorporates an approximate custodial SU(2), can be realized through the...
Transitions Between de Sitter Minima (2006)
Batra, Puneet, Kleban, Matthew
We investigate the cosmological signatures of instantons mediating tunneling between de Sitter minima. For generic potentials the Coleman-de Luccia instanton does not necessarily exist; when it does...
Measuring the W-t-b Interaction at the ILC (2006)
Batra, Puneet, Tait, Tim M. P.
The large top quark mass suggests that the top plays a pivotal role in Electroweak symmetry-breaking dynamics and, as a result, may have modified couplings to Electroweak bosons. Hadron colliders can...
Anomaly-Free Sets of Fermions (2005)
Batra, Puneet, Dobrescu, Bogdan A., Spivak, David
We present new techniques for finding anomaly-free sets of fermions. Although the anomaly cancellation conditions typically include cubic equations with integer variables that cannot be solved in...
Perturbative, Non-Supersymmetric Completions of the Little Higgs (2004)
Batra, Puneet, Kaplan, David E.
The little Higgs mechanism produces a light 100 GeV Higgs while raising the natural cutoff from 1 TeV to 10 TeV. We attempt an iterative little Higgs mechanism to produce multiple factors of 10...
Running into New Territory in SUSY Parameter Space (2004)
Batra, Puneet, Delgado, Antonio, Kaplan, David E., Tait, Tim M. P.
The LEP-II bound on the light Higgs mass rules out the vast majority of parameter space left to the Minimal Supersymmetric Standard Model (MSSM) with weak-scale soft-masses. This suggests the...
Diagonal symmetries beyond the standard model / (2004)
Batra, Puneet., Dimopoulos, Savas Advisor

The Higgs Mass Bound in Gauge Extensions of the Minimal Supersymmetric Standard Model (2003)
Batra, Puneet, Delgado, Antonio, Kaplan, David E., Tait, Tim M. P.
The minimal supersymmetric standard model, and extensions, have stringent upper bounds on the mass of the lightest Higgs boson if perturbativity up to the Planck scale is assumed. We argue that these...
Willick, Jeffrey A., Batra, Puneet
We present a measurement of the Hubble Constant based on Cepheid distances to 27 galaxies within 20 Mpc. We take the Cepheid data from published measurements by the Hubble Telescope Key Project on...
