91. $\pi^0$-hadron correlations in pp and Pb-Pb collisions and $\pi^0$ elliptic flow in Pb-Pb collisions measured at the ALICE experiment

The study of the azimuthal correlation and anisotropy with $\pi^0$ offers a powerful way to investigate the properties of strongly interacting matter created in ultra-relativistic heavy-ion collisions. In this talk, we present the measurement of two-particle correlations of $\pi^0$ trigger particles with associated charged particles versus azimuthal angle difference ($\Delta\varphi$) in pp and...

Dijet, dihadron, hadron-jet angular correlations have been reckoned as important probes of the transverse momentum broadening effects in relativistic nuclear collisions.
When a pair of high-energy jets created in hard collisions traverse the quark-gluon plasma produced in heavy-ion collisions, they become de-correlated due to the vacuum soft gluon radiation associated with the Sudakov...

The normalized dijet pseudorapidity distributions in pPb collisions can reveal the nuclear modifications of parton distribution functions (nPDF). Measurements as a function of average dijet transverse momentum could enable the test of the nPDF at different Q^2 scales. Moreover, recent theoretical studies based on NLO calculations show that the constraining power of pPb data on nPDF fits can be...

59. Characterizing the away-side jet with robust flow background subtraction via two-particle and three-particle correlations in Au+Au collisions at $\sqrt{s_{_\mathrm{NN}}}=200$ GeV in STAR

Jets are modified in relativistic heavy-ion collisions due to jet-medium interactions. Measurements of jet medium modifications have so far been obscure because of the large underlying anisotropic flow background. In this analysis we devise a novel method to subtract the flow background using data. We select events with a large recoil momentum ($P_x$) within a pseudorapidity ($\eta$) window of...

160. Heavy-flavor jets with CMS

Cheng-Chieh Peng (Purdue University (US))

The energy loss of jets in heavy-ion collisions is expected to depend on the mass and flavor of the initiating parton. Thus, measurements of jet quenching with identified partons place powerful constraints on the thermodynamic and transport properties of the hot and dense medium. We present recent result on heavy flavor jet spectra and nuclear modification factors of jets associated to charm...
