Forward-central two-particle correlations in p--Pb collisions with ALICE at the LHC

We present the results of measurements of two-particle angular correlations between trigger particles reconstructed in the ALICE Forward Muon Spectrometer ($-4.0 < \eta < -2.5$) and associated particles reconstructed in the central barrel detectors ($|\eta| < 1.0$) in p--Pb collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV. At low transverse momentum ($p_{\mathrm{T}}$), the reconstructed trigger particles mainly originate from weak decays of primary pions and kaons, whereas at high $p_{\mathrm{T}}$, they originate mainly from the decay of heavy-flavor particles. The ridge structure elongated in the $\eta$-direction, discovered recently in p--Pb collisions, is found to persist to the pseudorapidity ranges studied here. The second-order Fourier coefficients of muons are extracted after subtracting the correlations obtained in low-multiplicity events from those in high-multiplicity events. The ratio of coefficients in the Pb-going and p-going directions is presented as a function of $p_{\mathrm{T}}$, and the coefficients are observed to have a similar $p_{\mathrm{T}}$ dependence in both directions with the Pb-going coefficients larger by 16$\pm$6\%. The results are compared with calculations from a multi-phase transport model.Comment: 4 pages, 5 figures, Proceedings of the Hard Probes 2015, Montreal, Canad

A note on comonotonicity and positivity of the control components of decoupled quadratic FBSDE

In this small note we are concerned with the solution of Forward-Backward Stochastic Differential Equations (FBSDE) with drivers that grow quadratically in the control component (quadratic growth FBSDE or qgFBSDE). The main theorem is a comparison result that allows comparing componentwise the signs of the control processes of two different qgFBSDE. As a byproduct one obtains conditions that allow establishing the positivity of the control process.Comment: accepted for publicatio

Heavy-flavor jets in heavy-ion collisions

Heavy-flavor jets are a unique tool to study dynamical evolution of QCD systems via heavy-flavor particles, allowing one to access to the original parton kinematics and to separate out production and fragmentation effects. In these proceedings, various heavy-flavor jet results in pp, pA, and AA collisions are presented, extending the scope of heavy-flavor studies discussed at this conference series, the Strangeness in Quark Matter.</jats:p
