Dynamical magnetic enhancement of light and heavy quark jet quenching at RHIC

Alessandro Buzzatti, Miklos Gyulassy

A new Monte Carlo implementation of Djordjevic's dynamical scattering generalization of the DGLV radiative energy loss opacity series is used with a hybrid interpolation scheme to…

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…

Warped Universal Extra Dimensions

Anibal D. Medina, Eduardo Ponton

We consider a 5D warped scenario with a KK-parity symmetry, where the non-trivial warping arises from the dynamics that stabilizes the size of the extra dimension. Generically, the…

Non-conformal Holography of Heavy Quark Quenching

Andrej Ficnar, Jorge Noronha, Miklos Gyulassy

We develop a holographic (bottom-up) gravity model for QCD to understand the connection between the peak in the trace anomaly and the magnitude of heavy quark energy loss in a stro…

Strong longitudinal color field effects in pp collisions at energies available at the Large Hadron Collider

V. Topor Pop, M. Gyulassy, J. Barrette +2

We study the effect of strong longitudinal color fields (SCF) in p+p reactions up to Large Hadron Collider energies in the framework of the HIJING/BBbar v2.0 model that combines (c…

Origins of Hidden Sector Dark Matter II: Collider Physics

Clifford Cheung, Gilly Elor, Lawrence J. Hall +1

We consider a broad class of supersymmetric theories in which dark matter (DM) is the lightest superpartner (LSP) of a hidden sector that couples very weakly to visible sector fiel…

Origins of Hidden Sector Dark Matter I: Cosmology

Clifford Cheung, Gilly Elor, Lawrence J. Hall +1

We present a systematic cosmological study of a universe in which the visible sector is coupled, albeit very weakly, to a hidden sector comprised of its own set of particles and in…

kt-factorization for Hard Processes in Nuclei

Fabio Dominguez, Bo-Wen Xiao, Feng Yuan

Two widely proposed kt-dependent gluon distributions in the small-x saturation regime are investigated using two particle back-to-back correlations in high energy scattering proces…

Deviations of the Lepton Mapping Matrix from the Harrison-Perkins-Scott Form

R. Friedberg, T. D. Lee

We propose a simple set of hypotheses governing the deviations of the leptonic mapping matrix from the Harrison-Perkins-Scott (HPS) form. These deviations are supposed to arise ent…

On Taming the Warped Radion with Supersymmetry

Hooman Davoudiasl, Eduardo Ponton

In warped models that solve the hierarchy problem, there is generally no dynamical relation between the size of the fifth dimension and the scale of electroweak symmetry breaking (…

Impure Thoughts on Inelastic Dark Matter

Spencer Chang, Rafael F. Lang, Neal Weiner

The inelastic dark matter scenario was proposed to reconcile the DAMA annual modulation with null results from other experiments. In this scenario, WIMPs scatter into an excited st…

Ultra Visible Warped Model From Flavor Triviality & Improved Naturalness

Cédric Delaunay, Oram Gedalia, Seung J. Lee +2

A warped extra-dimensional model, where the Standard Model Yukawa hierarchy is set by UV physics, is shown to have a sweet spot of parameters with improved experimental visibility…

SUSY Higgs bosons and beyond

Marcela Carena, Eduardo Pontón, José Zurita

We consider extensions of the Minimal Supersymmetric Standard Model (MSSM) where the extra degrees of freedom interact weakly with the Higgs sector. These models allow to relax the…

BMSSM Higgs Bosons at the Tevatron and the LHC

Marcela Carena, Eduardo Ponton, Jose Zurita

We study extensions of the Minimal Supersymmetric Standard Model (MSSM) with new degrees of freedom that couple sizably to the MSSM Higgs sector and lie in the TeV range. After int…

Peaked Signals from Dark Matter Velocity Structures in Direct Detection Experiments

Rafael F. Lang, Neal Weiner

In direct dark matter detection experiments, conventional elastic scattering of WIMPs results in exponentially falling recoil spectra. In contrast, theories of WIMPs with excited s…

Correlations in impact-parameter space in a hierarchical saturation model for QCD at high energy

A. H. Mueller, S. Munier

In order to get an estimate of the homogeneity of the distribution of matter in a fast hadron or nucleus, we compute the correlations of the saturation scales Q_s between different…

The Hunt for New Physics at the Large Hadron Collider

P. Nath, B. D. Nelson, H. Davoudiasl +84

The Large Hadron Collider presents an unprecedented opportunity to probe the realm of new physics in the TeV region and shed light on some of the core unresolved issues of particle…
