Parallel Session VI: High pT hadron suppression in A+A (II)
- William Horowitz (University of Cape Town)
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...
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...
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...
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...
