On the sign of the dilaton in the soft wall models

Andreas Karch, Emanuel Katz, Dam T. Son +1

We elaborate on the existence of a spurious massless scalar mode in the vector channel of soft-wall models with incorrectly chosen sign of the exponential profile defining the wall…

Two Simple W' Models for the Early LHC

Martin Schmaltz, Christian Spethmann

W' gauge bosons are good candidates for early LHC discovery. We define two reference models, one containing a W'_R and one containing a W'_L, which may serve as ``simplified models…

Boosted objects: a probe of beyond the Standard Model physics

A. Abdesselam, E. Bergeaas Kuutmann, U. Bitenc +59

We present the report of the hadronic working group of the BOOST2010 workshop held at the University of Oxford in June 2010. The first part contains a review of the potential of ha…

Ditau-Jet Tagging and Boosted Higgses from a Multi-TeV Resonance

Andrey Katz, Minho Son, Brock Tweedie

New TeV-scale physics processes at the LHC can produce Higgs bosons with substantive transverse Lorentz boost, such that the Higgs's decay products are nominally contained in a sin…

A Light Scalar in Low-Scale Technicolor

Antonio Delgado, Kenneth Lane, Adam Martin

In addition to the narrow spin-one resonances , and occurring in low-scale technicolor, there will be relatively narrow scalars in the mass range 200 to 600--700 G…

Jet Substructure and the Search for Neutral Spin-One Resonances in Electroweak Boson Channels

Andrey Katz, Minho Son, Brock Tweedie

Strongly coupled models at the TeV scale often predict one or more neutral spin-one resonances (Z') which have appreciable branching fractions to electroweak bosons, namely the Hig…

Multivariate discrimination and the Higgs + W/Z search

Kevin Black, Jason Gallicchio, John Huth +3

A systematic method for optimizing multivariate discriminants is developed and applied to the important example of a light Higgs boson search at the Tevatron and the LHC. The Signi…

QED confronts the radius of the proton

A. De Rújula

Recent results on muonic hydrogen [1] and the ones compiled by CODATA on ordinary hydrogen and -scattering [2] are away from each other. Two reasons justify a further look…

Parity Doubling and the S Parameter Below the Conformal Window

Thomas Appelquist, Ron Babich, Richard C. Brower +11

We describe a lattice simulation of the masses and decay constants of the lowest-lying vector and axial resonances, and the electroweak S parameter, in an SU(3) gauge theory with $…

QED is not endangered by the proton's size

A. De Rújula

Pohl et al. have reported a very precise measurement of the Lamb-shift in muonic Hydrogen, from which they infer the radius characterizing the proton's charge distribution. The res…

Dark Moments and the DAMA-CoGeNT Puzzle

A. Liam Fitzpatrick, Kathryn M. Zurek

We consider the velocity dependence arising from scattering through dark multipole moments, and its effects on the consistency of the signals observed by DAMA and CoGeNT with the d…

Luminous Dark Matter

Brian Feldstein, Peter W. Graham, Surjeet Rajendran

We propose a dark matter model in which the signal in direct detection experiments arises from electromagnetic, not nuclear, energy deposition. This can provide a novel explanation…

Efficient Identification of Boosted Semileptonic Top Quarks at the LHC

Keith Rehermann, Brock Tweedie

Top quarks produced in multi-TeV processes will have large Lorentz boosts, and their decay products will be highly collimated. In semileptonic decay modes, this often leads to the…

The Bestest Little Higgs

Martin Schmaltz, Daniel Stolarski, Jesse Thaler

While little Higgs models provide an interesting way to address the hierarchy problem, concrete models in the literature typically face two major obstacles. First, the mechanism fo…

Implications of CoGeNT and DAMA for Light WIMP Dark Matter

A. Liam Fitzpatrick, Dan Hooper, Kathryn M. Zurek

In this paper, we study the recent excess of low energy events observed by the CoGeNT collaboration, and discuss the possibility that these events originate from the elastic scatte…

Discovering Asymmetric Dark Matter with Anti-Neutrinos

Brian Feldstein, A. Liam Fitzpatrick

We discuss possible signatures of Asymmetric Dark Matter (ADM) through dark matter decays to neutrinos. We specifically focus on scenarios in which the Standard Model (SM) baryon a…

Further study of neutrino oscillation with two detectors in Kamioka and Korea

F. Dufour, T. Kajita, E. Kearns +1

This paper updates and improves the study of electron neutrino appearance in the framework of two far detectors at different oscillation maxima, specifically, Tokai-To-Kamioka-to-K…

Higgs look-alikes at the LHC

A. De Rujula, Joseph Lykken, Maurizio Pierini +2

The discovery of a Higgs particle is possible in a variety of search channels at the LHC. However the true identity of any putative Higgs boson will at first remain ambiguous, unti…
