  • Charge-dependent azimuthal particle correlations with respect to the second-order event plane in p-Pb and PbPb collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV have been studied with the CMS experiment at the LHC. We performed the measurement with a three-particle correlation technique, using two particles with the same or opposite charge within the pseudorapidity range |η|<2.4, and a third particle measured in the hadron forward calorimeters (4.4<|η|<5). We also observed differences between the same and opposite sign correlations, as functions of multiplicity and η gap between the two charged particles, and found that they were of similar magnitude in p-Pbmore » and PbPb collisions at the same multiplicities. Our results pose a challenge for the interpretation of charge-dependent azimuthal correlations in heavy ion collisions in terms of the chiral magnetic effect.« less

  • Charge-dependent azimuthal correlations of same- and opposite-sign pairs with respect to the second- and third-order event planes have been measured in pPb collisions at sqrt(s[NN]) = 8.16 TeV and PbPb collisions at 5.02TeV with the CMS experiment at the LHC. The measurement is motivated by the search for the charge separation phenomenon predicted by the chiral magnetic effect (CME) in heavy ion collisions. Three- and two-particle azimuthal correlators are extracted as functions of the pseudorapidity difference, the transverse momentum (pt) difference, and the pt average of same- and opposite-charge pairs in various event multiplicity ranges. The data suggest that themore » charge-dependent three-particle correlators with respect to the second- and third-order event planes share a common origin, predominantly arising from charge-dependent two-particle azimuthal correlations coupled with an anisotropic flow. The CME is expected to lead to a v[2]-independent three-particle correlation when the magnetic field is fixed. Using an event shape engineering technique, upper limits on the v[2]-independent fraction of the three-particle correlator are estimated to be 6.6% for pPb and 3.8% for PbPb collisions at 95% confidence level. The results of this analysis, both the dominance of two-particle correlations as a source of the three-particle results and the similarities seen between PbPb and pPb, provide stringent constraints on the origin of charge-dependent three-particle azimuthal correlations and challenge their interpretation as arising from a chiral magnetic effect in heavy ion collisions.« less
  • We study the dynamics of chiral phase transition in the O(4) linear sigma model by using the time-dependent variational approach with squeezed states. Our numerical simulations show that large domains of the disoriented chiral condensate (DCC) are formed through the mode-mode correlation. We also present a result of an analysis of the two-particle correlation function for the pion fields, which reflects unique nature of the squeezed states. In particular, we will show that the chaoticity parameter is not close to zero even if DCC domains are produced.
  • The magnetic analog of odd-time superconducting order is introduced. It is shown that the classification of possible odd-time magnetic states admits the existence of a novel state---the [ital chiral] [ital spin] [ital nematic]---which is characterized by an odd-in-time spin-spin correlation function. The known example of the [ital chiral] [ital spin] [ital liquid] appears naturally in this approach. The equal-time correlation function of these odd-in-time states involves nontrivial three-spin correlations.
