Systematic Uncertainties in Theoretical Predictions of Jet Quenching

W. A. Horowitz, B. A. Cole

We find that the current radiative energy loss kernels obtained from the opacity expansion dramatically violate the collinear approximation used in their derivation. By keeping onl…

Supersymmetric Higgs Bosons and Beyond

Marcela Carena, Kyoungchul Kong, Eduardo Ponton +1

We consider supersymmetric models that include particles beyond the Minimal Supersymmetric Standard Model (MSSM) with masses in the TeV range, and that couple significantly to the…

Warped 5-Dimensional Models: Phenomenological Status and Experimental Prospects

Hooman Davoudiasl, Shrihari Gopalakrishna, Eduardo Ponton +1

Warped 5-dimensional models, based on the original Randall-Sundrum geometry, have been extended beyond their initial purpose of resolving the gauge hierarchy problem. Over the past…

Thermal Width of the at Large t' Hooft Coupling

Jorge Noronha, Adrian Dumitru

We use the AdS/CFT correspondence to show that the heavy quark (static) potential in a strongly-coupled plasma develops an imaginary part at finite temperature. Thus, deeply bound…

Constraints on AdS/CFT Gravity Dual Models of Heavy Ion Collisions

Jorge Noronha, Miklos Gyulassy, Giorgio Torrieri

We show that the five-fold constraints due to (1) the observed nuclear modification of heavy quark jets measured via non-photonic electrons in cent…

A lattice test of strong coupling behaviour in QCD at finite temperature

E. Iancu, A. H. Mueller

We propose a set of lattice measurements which could test whether the deconfined, quark-gluon plasma, phase of QCD shows strong coupling aspects at temperatures a few times the cri…

Semi-inclusive Deep Inelastic Scattering at small x

Cyrille Marquet, Bo-Wen Xiao, Feng Yuan

We study the semi-inclusive hadron production in deep inelastic scattering at small . A transverse momentum dependent factorization is found consistent with the results calculat…

A Timeon Model of Quark and Lepton Mass Matrices

R. Friedberg, T. D. Lee

It is proposed that violation in physics, as well as the masses of electron and quarks, arise from a pseudoscalar interaction with a new spin 0 field , odd in …

Gaps between jets at hadron colliders in the next-to-leading BFKL framework

F. Chevallier, O. Kepka, C. Marquet +1

We investigate diffractive events in hadron-hadron collisions, in which two jets are produced and separated by a large rapidity gap. In perturbative QCD, the hard color-singlet obj…

B-Decay Signatures of Warped Top-Condensation

Hooman Davoudiasl, Eduardo Ponton

We point out that the light radion phi in a recently proposed Warped Top-Condensation Model, can provide distinct signatures in b -> s phi, where the on-shell phi can decay with di…

The Heavy Quark Potential as a Function of Shear Viscosity at Strong Coupling

Jorge Noronha, Adrian Dumitru

We determine finite temperature corrections to the heavy-quark (static) potential as a function of the shear viscosity to entropy density ratio in a strongly coupled, large- c…

Soft Open Charm Production in Heavy-Ion Collisions

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

Effects of strong longitudinal color electric fields (SCF) on the open charm production in nucleus-nucleus (A + A) collisions at 200A GeV are investigated within the framework of t…

Renormalization of quark bilinear operators in a momentum-subtraction scheme with a nonexceptional subtraction point

C. Sturm, Y. Aoki, N. H. Christ +3

We extend the Rome-Southampton regularization independent momentum-subtraction renormalization scheme(RI/MOM) for bilinear operators to one with a nonexceptional, symmetric subtrac…
