111. Strangeness production and nuclear modification at LHC energies

Oliver Busch (University of Tsukuba (JP))

25/09/2016, 10:40

The presence of a strongly interacting medium produced in relativistic
heavy-ion (AA) collisions modifies the final transverse momentum (p$_{\mathrm{T}}$) spectra of hadrons with respect to proton-proton (pp) collisions. While the production at high-p$_{\mathrm{T}}$ is suppressed by in-medium energy loss of high-p$_{\mathrm{T}}$ partons, at lower p$_{\mathrm{T}}$ other mechanisms...

196. Measurement of azimuthal flow of soft and high-pT charged particles in 5.02 TeV Pb+Pb collisions with the ATLAS detector

The new experimental data collected by the ATLAS experiment during the 2015 heavy ion LHC run offers new opportunities to study properties of Quark-Gluon Plasma at unprecedented high temperatures and densities. Study of the azimuthal anisotropy of produced particles not only constrains our understanding of initial conditions of nuclear collisions and soft particle collective dynamics but also...

31. Beyond the Poisson Approximation: n Gluon Radiation in QGP

Andriniaina Rasoanaivo (University of Cape Town)

25/09/2016, 11:20

We present a novel technique for the calculation of the probability for emission of an arbitrary number of gluons radiated from a high-pT probe of the QGP. Our work is an extension of the maximal helicity violating (MHV) method in which the usual soft-collinear factor is classified according to its symmetry under gluon permutations.

For the purposes of illustration, we show the explicit form...

99. Medium modification of jet charge in heavy-ion collisions

Shi-Yong Chen (CCNU)

The momentum-weighted sum of the charges inside a jet provides an experimental handle on the electric charge of fundamental strongly-interacting particles. Knowing the charge of the parton initiating a light-quark jet could be extremely useful both for testing aspects of the Standard Model and for characterizing potential beyond-the-Standard-Model signals not only in pp collisions, but also...

175. The x and scale dependence of the transport coefficient $\hat{q}$

Abhijit Majumder (Wayne state university)

25/09/2016, 12:00

We take a closer look at the single particle nuclear modification factor ($R_{AA}$) and azimuthal anisotropy ($v_{2}$) of leading hadrons at high transverse momentum ($p_{T}$) at both RHIC and LHC collision energies. We focus on the established reduction in the interaction measure $\hat{q}/T^{3}$ between RHIC and LHC, as discovered by the JET collaboration. The centrality dependence of the...
