Atoms in Flight and the Remarkable Connections between Atomic and Hadronic Physics

Stanley J. Brodsky

Atomic physics and hadron physics are both based on Yang Mills gauge theory; in fact, quantum electrodynamics can be regarded as the zero-color limit of quantum chromodynamics. I r…

Pair Production Constraints on Superluminal Neutrinos Revisited

Stanley J. Brodsky, Susan Gardner

We revisit the pair creation constraint on superluminal neutrinos considered by Cohen and Glashow in order to clarify which types of superluminal models are constrained. We show th…

Hiding a Heavy Higgs Boson at the 7 TeV LHC

Yang Bai, JiJi Fan, JoAnne L. Hewett

A heavy Standard Model Higgs boson is not only disfavored by electroweak precision observables but is also excluded by direct searches at the 7 TeV LHC for a wide range of masses.…

Comments on Gaugino Screening

Timothy Cohen, Anson Hook, Brian Wecht

Gauge mediated models of supersymmetry breaking often exhibit "gaugino screening," where to leading order in F, gaugino masses are unaffected by higher dimensional Kahler potential…

BL Lacertae objects beyond redshift 1.3 - UV-to-NIR photometry and photometric redshift for Fermi/LAT blazars

Arne Rau, P. Schady, J. Greiner +17

Observations of the gamma-ray sky with Fermi led to significant advances towards understanding blazars, the most extreme class of Active Galactic Nuclei. A large fraction of the po…

2d affine XY-spin model/ 4d gauge theory duality and deconfinement

Mohamed M. Anber, Erich Poppitz, Mithat Unsal

We introduce a duality between two-dimensional XY-spin models with symmetry-breaking perturbations and certain four-dimensional SU(2)and SU(2)/Z_2 gauge theories, compactified on a…

Unitarity and the Holographic S-Matrix

A. Liam Fitzpatrick, Jared Kaplan

The bulk S-Matrix can be given a non-perturbative definition in terms of the flat space limit of AdS/CFT. We show that the unitarity of the S-Matrix, ie the optical theorem, can be…

A Non Standard Model Higgs at the LHC as a Sign of Naturalness

Asimina Arvanitaki, Giovanni Villadoro

Light states associated with the hierarchy problem affect the Higgs LHC production and decays. We illustrate this within the MSSM and two simple extensions applying the latest boun…

Measuring the Invisible Higgs Width at the 7 and 8 TeV LHC

Yang Bai, Patrick Draper, Jessie Shelton

The LHC is well on track toward the discovery or exclusion of a light Standard Model (SM)-like Higgs boson. Such a Higgs has a very small SM width and can easily have large branchi…
