113. Light messengers from heavy quarks - Measurements of leptons from heavy-flavor decays with ALICE at the LHC

"Light messengers from heavy quarks - Measurements of leptons from heavy-flavor decays with ALICE at the LHC R. Averbeck (GSI) for the ALICE Collaboration Hadrons carrying heavy flavor, i.e. charm or beauty quarks, are unique probes in hadronic collisions at high energies. Given their large masses charm and beauty quark-antiquark pairs are produced almost exclusively via hard parton...

114. Heavy-flavour production as a function of multiplicity in pp and p-Pb collisions with the ALICE detector at the LHC

"The measurement of heavy-flavour production cross sections in pp collisions at the LHC represents a test for pQCD calculations and provides a reference for heavy-ion studies. The study of heavy-flavour production as a function of multiplicity of charged particles produced in the collisions could give insight into the role of multi-parton interactions (MPI) and on the interplay between hard...

97. Heavy Flavor Results in Cold Nuclear Matter from PHENIX

Darren McGlinchey (University of Colorado)

Charm and bottom quarks, formed primarily from gluon fusion in the initial hard scatterings at RHIC, provide a rich probe with which to study the many interesting physics effects present in p(d)+A collisions including energy loss, gluon saturation, and nuclear parton distribution modification. By measuring the production of both open heavy flavor and closed heavy flavor, in the form of...

133. Flow Measurements and selection of body-body and tip-tip enhanced samples in U+U collisions at STAR

The azimuthal anisotropy of particle production is commonly used in high-energy nuclear collisions to study the early evolution of the expanding system. The prolate shape of uranium nuclei provides the possibility to study how the initial geometry of the nuclei affects the azimuthal distributions. It also provides a unique opportunity to understand the initial conditions for particle...

99. Correlation results from CMS

Zhenyu Chen (Rice University (US))

Latest results of particle correlations in pPb and PbPb collisions at the LHC from the CMS experiment will be presented. In particular, focus will be given to the studies of long-range two-particle correlations (known as the "Ridge") observed in high-multiplicity pPb collisions and their implications to collective phenomena in small systems. These correlations are studied as a function of...

96. Femtoscopy in d-Au collisions

The HBT analysis for pions emitted in d-Au collisions at 200GeV is discussed. The HBT radii are calculated and compared to experiment. Predictions are made for HBT parameters that can be observed in asymmetric p-Pb or d-Au collisions. Azimuthal angle sensitive HBT analysis in d-Au collisions yields a pronounced azimuthal angle dependence of the radii.

90. Quantum coherence measurements using two-, three-, and four-pion Bose-Einstein correlations

Dhevan Raja Gangadharan (Lawrence Berkeley National Lab. (US))

05/12/2014, 16:20

"Coherence of pions in the final state is known to suppress Bose-Einstein correlations. The amount of suppression increases for higher order correlations. We present a new method to measure the coherent fraction of pions using multi-pion Bose-Einstein correlations. The comparison of two-, three-, and four-pion correlations allows for a more unambiguous measure of the coherent fraction....
