Higgs Mass Prediction for Realistic String/M Theory Vacua

Gordon Kane, Piyush Kumar, Ran Lu +1

Recently it has been recognized that in compactified string/M-theories that satisfy cosmological constraints, it is possible to derive some robust and generic predictions for parti…

Unruh gamma radiation at RHIC?

T. S. Biro, M. Gyulassy, Z. Schram

Varying the proposition that acceleration itself would simulate a thermal environment, we investigate the semiclassical photon radiation as a possible telemetric thermometer of acc…

BMSSM Higgs Bosons at the 7 TeV LHC

Marcela Carena, Eduardo Ponton, Jose Zurita

We consider the Higgs sector in extensions of the Minimal Supersymmetric Standard Model by higher-dimension operators in the superpotential and the Kähler potential, in the context…

Confronting Recent Neutrino Oscillation Data with Sterile Neutrinos

G. Karagiorgi

Recent neutrino oscillation results have evoked renewed interest in sterile neutrino oscillation models. This paper reviews the data from MiniBooNE and short-baseline reactor antin…

Gluon saturation effects on the color singlet J/Psi production in high energy dA and AA collisions

F. Dominguez, D. E. Kharzeev, E. M. Levin +2

We derive the formulae for the cross section of J/Psi production in high energy pA and AA collisions taking into account the gluon saturation/color glass condensate effects. We the…

On the linearly polarized gluon distributions in the color dipole model

Fabio Dominguez, Jian-Wei Qiu, Bo-Wen Xiao +1

We show that the linearly polarized gluon distributions appear in the color dipole model as we derive the full cross sections of the DIS dijet production and the Drell-Yan dijet ($…

On the small-x evolution of the color quadrupole and the Weizsäcker-Williams gluon distribution

Fabio Dominguez, A. H. Mueller, Stéphane Munier +1

Color quadrupoles have been found to be important in the proper description of observables sensitive to the small-x regime in nuclei as well as in the operator definition of the We…

Phenomenology of Non-Custodial Warped Models

Adrian Carmona, Eduardo Ponton, Jose Santiago

We study the effect of bulk fermions on electroweak precision observables in a recently proposed model with warped extra dimensions and no custodial symmetry. We find that the top-…

Electroweak Symmetry Breaking in the DSSM

Jonathan J. Heckman, Piyush Kumar, Cumrun Vafa +1

We study the theoretical and phenomenological consequences of modifying the Kahler potential of the MSSM two Higgs doublet sector. Such modifications naturally arise when the Higgs…

Quenching and Tomography from RHIC to LHC

W. A. Horowitz, Miklos Gyulassy

We compare fully perturbative and fully nonperturbative pictures of high-pT energy loss calculations to the first results from LHC. While over-suppressed compared to published ALIC…

Electroweak Baryogenesis and Dark Matter with an approximate R-symmetry

Piyush Kumar, Eduardo Ponton

It is well known that R-symmetric models dramatically alleviate the SUSY flavor and CP problems. We study particular modifications of existing R-symmetric models which share the so…

Jet Quenching in Non-Conformal Holography

Andrej Ficnar, Jorge Noronha, Miklos Gyulassy

We use our non-conformal holographic bottom-up model for QCD described in 1012.0116 to further study the effect of the QCD trace anomaly on the energy loss of both light and heavy…

Jet Flavor Tomography of Quark Gluon Plasmas at RHIC and LHC

Alessandro Buzzatti, Miklos Gyulassy

A new Monte Carlo model of jet quenching in nuclear collisions, CUJET1.0, is applied to predict the jet flavor dependence of the nuclear modification factor for fragments {\it $f=π…

Comparison of Jet Quenching Formalisms for a Quark-Gluon Plasma "Brick"

Nestor Armesto, Brian Cole, Charles Gale +12

We review the currently available formalisms for radiative energy loss of a high-momentum parton in a dense strongly interacting medium. The underlying theoretical framework of the…

Warped Radion Dark Matter

Anibal D. Medina, Eduardo Ponton

Warped scenarios offer an appealing solution to the hierarchy problem. We consider a non-trivial deformation of the basic Randall-Sundrum framework that has a KK-parity symmetry. T…

Short-baseline Neutrino Oscillation Waves in Ultra-large Liquid Scintillator Detectors

Sanjib Kumar Agarwalla, J. M. Conrad, M. H. Shaevitz

Powerful new multi-kiloton liquid scintillator neutrino detectors, including NOvA and LENA, will come on-line within the next decade. When these are coupled with a modest-power dec…

Proton-Nucleus Collisions at the LHC: Scientific Opportunities and Requirements

C. A. Salgado, J. Alvarez-Muniz, F. Arleo +27

Proton-nucleus (p+A) collisions have long been recognized as a crucial component of the physics programme with nuclear beams at high energies, in particular for their reference rol…

Baryon anomaly and strong color fields in Pb+Pb collisions at 2.76A TeV at the CERN Large Hadron Collider

V. Topor Pop, M. Gyulassy, J. Barrette +1

With the HIJING/BBbar v2.0 heavy ion event generator, we explore the phenomenological consequences of several high parton density dynamical effects predicted in central Pb+Pb colli…

The Surprising Transparency of the sQGP at LHC

W. A. Horowitz, Miklos Gyulassy

We present parameter-free predictions of the nuclear modification factor, R_{AA}^pi(p_T,s), of high p_T pions produced in Pb+Pb collisions at sqrt{s}_{NN}=2.76 and 5.5 ATeV based o…

Extraordinary Phenomenology from Warped Flavor Triviality

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

Anarchic warped extra dimensional models provide a solution to the hierarchy problem. They can also account for the observed flavor hierarchies, but only at the expense of little h…
