The QCD Equation of State in Small Systems
W. A. Horowitz, Alexander Rothkopf
We present first results on finite system size corrections to the equation of state, trace anomaly, and speed of sound for two model systems: 1) free, massless scalar theory and 2)…
B-meson Nuclear Modification Factor and in a Strongly Coupled Plasma in Collisions at TeV and TeV
B. A. Ngwenya, W. A. Horowitz
We present predictions for the suppression of B-mesons using AdS/CFT techniques assuming a strongly coupled quark-gluon plasma at TeV for central collisions an…
Heavy flavour energy loss from AdS/CFT: A novel diffusion coefficient
Robert Hambrock, William Alexander Horowitz
Two AdS/CFT based energy loss models are used to compute the suppression and azimuthal correlations of heavy quarks in heavy ion collisions. The model with a velocity independent d…
Two Gluon Emission from MHV: Two Particle Correlations and the Deviation from Poisson
A. N. Rasoanaivo, W. A. Horowitz
We derive the momentum distribution for two soft and collinear gluons emitted from an off-shell quark, modeled by a scattering process and computed using the ma…
Bottomonia Suppression in Heavy Ion Collisions from AdS/CFT
N. N. Barnard, W. A. Horowitz
We compute for the first time the suppression of bottomonia in a strongly coupled QGP and compare the results to those from a weakly coupled QGP. Using imaginary time techniques we…
Time Dependent from AdS/CFT
W. A. Horowitz
We present the first ever AdS/CFT calculation of for a light quark jet as a function of position or, equivalently, time. Our result does not suffer from the gamma factor…
Short path length corrections to Djordjevic-Gyulassy-Levai-Vitev energy loss
Isobel Kolbé, W. A. Horowitz
We compute the correction to the energy loss of a hard parton due to short separation distances between the creation of the particle and the in-medium scattering center that stimul…
Short path length pQCD corrections to energy loss in the quark gluon plasma
Isobel Kolbe
Recent surprising discoveries of collective behaviour of low- particles in collisions at LHC hint at the creation of a hot, fluid-like QGP medium. The seemingly conflicti…
Testing pQCD and AdS/CFT Energy Loss at RHIC and LHC
W. A. Horowitz
We compare calculations of jet quenching observables at sqrt s = 2.76 ATeV to preliminary LHC data from weak-coupling pQCD and strong-coupling AdS/CFT drag energy loss models. Rigo…
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…
Running coupling corrections to inclusive gluon production
W. A. Horowitz, Yuri V. Kovchegov
We calculate running coupling corrections for the lowest-order gluon production cross section in high energy hadronic and nuclear scattering using the BLM scale-setting prescriptio…
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…
Measuring the Gluon Density in e + A Collisions: KLN CGC, DGLAP Glauber, or Neither?
W. A. Horowitz
We predict readily experimentally measurable differences in the diffractive cross section in the coherent exclusive photoproduction of J/psi mesons in e + A collisions at eRHIC and…
Qualitative and Quantitative Energy Loss?
W. A. Horowitz
Despite the 300% systematic theoretical uncertainty associated with extracting qhat using current energy loss models due to the collinear approximation, and despite the uncertainti…
Running Coupling Corrections to High Energy Inclusive Gluon Production
W. A. Horowitz, Yuri V. Kovchegov
We calculate running coupling corrections for the lowest-order gluon production cross section in high energy hadronic and nuclear scattering using the BLM scale-setting prescriptio…
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…
