779. Production of $\Sigma$(1385)$^{\pm}$ and $\Xi$(1530)$^{0}$ measured by ALICE in pp, p--Pb and Pb--Pb collisions at the LHC

Jihye Song (Pusan National University (KR))

Oral

The measurement of resonances in ultra-relativistic heavy-ion collisions allows one to study the properties of the hadronic medium. Resonances with short lifetimes compared to the duration of the hadronic phase are good candidates to probe the interplay of particle re-scattering and regeneration in the hadronic phase, which result in a modification of the measured yield of resonances.

780. Measurement of the longitudinal decorrelation of event-plane angle and flow magnitudes in 2.76 and 5.02 TeV Pb+Pb collisions with the ATLAS detector

Peng Huo (State University of New York (US))

Oral

Longitudinal dynamics has recently become a topic of great interest in the study of ultra-relativistic heavy ion collisions. Measurement of the longitudinal fluctuations of the flow harmonic coefficients $v_n$ and event-plane angles $Psi_n$ can provide a more complete picture of space-time evolution of the hot, dense medium formed in heavy ion collisions. Longitudinal flow decorrelations can...

782. B meson nuclear modification factor in PbPb at 5.02 TeV with CMS

Gian Michele Innocenti (Massachusetts Inst. of Technology (US))

Oral

The study of beauty production in heavy-ion collisions is considered one of the key measurement to address the flavour-dependence of in-medium energy loss in PbPb collisions. In pPb collisions, studies of b-quark production can also provide insights into the relevance of cold nuclear matter effects in the heavy-flavour sector. The CMS experiment has excellent capabilities for measuring b-quark...

783. Forward/Backward asymmetry of v_n in Cu+Au at RHIC-PHENIX

Hiroshi Nakagomi (Tsukuba University), Mr Hiroshi Nakagomi (Tsukuba University)

Oral

Azimuthal anisotropies of particle production in high energy heavy ion collisions have proven to be an excellent tool for investigating the initial geometry and the bulk properties of the Quark Gluon Plasma (QGP). Azimuthal anisotropy, measured through Fourier coefficients v_n, have been measured at mid-rapidity and are used to constrain the initial geometry and viscosity-over-entropy ratio...

784. $\Lambda_{c}^+$ production in Au+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV at the STAR experiment

Guannan Xie (LBNL/USTC)

11/02/2017, 10:20

Oral

Charm quarks, predominantly produced in the early stage of heavy-ion collisions, are believed to provide unique information on the hot and dense medium created in such collisions. At RHIC, an enhancement in baryon-to-meson ratios for light hadrons and hadrons containing strange quarks has been observed in central heavy-ion collisions compared to p+p and peripheral heavy-ion collisions in the...

785. In-Medium Bottomonium Production in Heavy-Ion Collisions

Xiaojian Du (Texas A&M University)

11/02/2017, 10:25

Oral

We study bottomonium production at RHIC and the LHC using a transport model including both suppression and regeneration mechanisms. The transport model utilizes a kinetic rate equation [1] to calculate the centrality dependence of the production yields, and a Boltzmann equation for transverse-momentum ($p_T$) spectra. It has been successful in describing and predicting charmonium data at SPS,...

786. Gluonic hot spots and spatial correlations inside the proton

Alba Soto Ontoso (UGR/FIAS)

11/02/2017, 10:30

Oral

In this talk, based on arXiv:1605.09176, we present a microscopic realization of the hollowness effect observed in proton-proton scattering at $\sqrt s = 7$ TeV. The initial collision geometry proposed in our model could impact significantly the interpretation of data specially sensitive to it, like the eccentricities of proton-proton, proton-nucleus and nucleus-nucleus collisions.
The...

787. Susceptibilities from a black hole engineered EoS with a critical point

Israel Portillo (University of Houston)

11/02/2017, 10:35

Oral

Currently at the Beam Energy Scan at RHIC experimental efforts are being made to find the QCD critical point. On the theoretical side, the behavior of higher-order susceptibilities of the net-baryon charge from Lattice QCD may allows us to estimate its position via Taylor expansion of the density of states at $\mu_B=0$. However, even if the series expansion continues to higher-orders, there is...
