Near Zone Navier-Stokes Analysis of Heavy Quark Jet Quenching in an =4 SYM Plasma

Jorge Noronha, Giorgio Torrieri, Miklos Gyulassy

The near zone energy-momentum tensor of a supersonic heavy quark jet moving through a strongly-coupled SYM plasma is analyzed in terms of first-order Navier-Stokes…

On the anomalous dimensions of the multiple pomeron exchanges

Bo-Wen Xiao

High energy hard scattering in large limit can be described by the QCD dipole model. In this paper, single, double and triple BFKL pomeron exchange amplitudes are computed…

Is Strangeness Still Strange at the LHC?

G. G. Barnafoldi, G. Fai, P. Levai +2

Strangeness production is calculated in a pQCD-based model (including nuclear effects) in the high transverse momentum sector, where pQCD is expected to work well. We investigate p…

Physics at a future Neutrino Factory and super-beam facility

The ISS Physics Working Group

The conclusions of the Physics Working Group of the international scoping study of a future Neutrino Factory and super-beam facility (the ISS) are presented. The ISS was carried by…

Symmetry Breaking Patterns for the Little Higgs from Strong Dynamics

Puneet Batra, Z. Chacko

We show how the symmetry breaking pattern of the simplest little Higgs model, and that of the smallest moose model that incorporates an approximate custodial SU(2), can be realized…

Jarlskog Invariant of the Neutrino Mapping Matrix

R. Friedberg, T. D. Lee

The Jarlskog Invariant of the neutrino mapping matrix is calculated based on a phenomenological model which relates the smallness of light lepton masses and …

Heavy-Quark Kinetics in the QGP at LHC

H. van Hees, V. Greco, R. Rapp

We present predictions for the nuclear modification factor and elliptic flow of D and B mesons, as well as of their decay electrons, in semicentral Pb-Pb collisions at the LHC. Hea…

Thermal Dileptons at LHC

H. van Hees, R. Rapp

We predict dilepton invariant-mass spectra for central 5.5 ATeV Pb-Pb collisions at LHC. Hadronic emission in the low-mass region is calculated using in-medium spectral functions o…

Hidden Symmetry of the CKM and Neutrino Mapping Matrices

R. Friedberg, T. D. Lee

We propose that the smallness of the light quark masses is related to the smallness of the T violation in hadronic weak interactions. Accordingly, for each of the two quark sectors…

Stopping Power from SPS to LHC energies

V. Topor Pop, J. Barrette, C. Gale +2

We investigate the energy dependence of hadron production and of stopping power based on HIJING/BBbar v2.0 model calculations. Pseudorapidity spectra and transverse momentum distri…

(Multi)Strangeness Production in Pb+Pb collisions at LHC. HIJING/BBar v2.0 predictions

V. Topor Pop, J. Barrette, C. Gale +2

Strangeness and multi-strangeness particles production can be used to explore the initial transient field fluctuations in heavy ion collisions. We emphasize the role played by Junc…

Correlation of small-x gluons in impact parameter space

Y. Hatta, A. H. Mueller

In the framework of the QCD dipole model at high energy, we present an analytic evaluation of the dipole pair density in two limits in which the parent dipole is much larger/smalle…

Does the Cronin Peak Disappear at LHC Energies?

G. G. Barnafoldi, P. Levai, G. Fai +2

In this work we compare the nuclear modification factors in proton (deuteron) -- nucleus collisions at CERN SPS, FNAL and RHIC energies in a wide p_T range. In these experiments th…

Neutral kaon mixing from 2+1 flavor Domain Wall QCD

D. J. Antonio, P. A. Boyle, T. Blum +16

We present the first results for neutral kaon mixing using 2+1 flavors of domain wall fermions. A new approach is used to extrapolate to the physical up and down quark masses from…

Novel heavy flavor suppression mechanisms in the QGP

Ivan Vitev, Azfar Adil, Hendrik van Hees

We revisit the question of the measured, unexpectedly large, heavy flavor suppression, , in nucleus-nucleus collisions at RHIC and compare two new theoretical ap…

Electroweak constraints on warped models with custodial symmetry

Marcela Carena, Eduardo Ponton, Jose Santiago +1

It has been recently argued that realistic models with warped extra dimensions can have Kaluza-Klein particles accessible at the Large Hadron Collider if a custodial symmetry, SU(2…
