DESCRIPTION:Speakers: RILEY\, Charles (Yale University)\nThree-particle co
 rrelations have been used to probe for local parity violation (LPV) in the
  quark-gluon plasma (QGP) formed during Au+Au collisions at $\\sqrt{s_{NN}
 }$ = 200 GeV at RHIC [1]. Further expanding on this analysis\, we present 
 our results on looking at these correlations through pairing kaons and pio
 ns produced during the collision events (while fixing the third particle t
 o be another pion). The idea behind looking at kaon-pion (K-Pi) correlatio
 ns is that the two-body correlations between these distinct particles are 
 weaker than those between pions with themselves. It may be that the tenden
 cy of two pions to be emitted at small angles to one another can be an imp
 ortant ingredient in a strong interaction background [2]. Hence\, looking 
 at K-Pi correlations may reduce potential effects from such backgrounds an
 d possibly other parity-even effects that may contribute to the three-part
 icle correlator.\n\nWe present charge dependent azimuthal correlations bet
 ween pions and kaons identified by using the Time-Of-Flight detector as a 
 function of centrality\, $\\delta\\eta$ and $\\deltap_{T}$ between pairs i
 n Au+Au collisions at $\\sqrt{s_{NN}}$ = 200 GeV. Modifications depending 
 on elliptic flow are also applied to the correlators as an additional meas
 ure to possibly reduce P-even background effects on the three-particle cor
 relators.\n\n[1] B. I. Abelev et al.\, Phys. Rev. C81 (2010) 54908.\n\n[2]
