T. Csörgő 1,2 for the PHENIX Collaboration Femtoscopic results in Au+Au & p+p from PHENIX at RHIC 1 MTA KFKI RMKI, Budapest, Hungary 2 Department of Physics, Harvard University, Cambridge, USA. Topics: - Bose-Einstein correlations of charged kaons in 200 GeV Au+Au collisions comparisons ( ± -s, K 0 -s of STAR) ‏ m t and N part scaling of 3d HBT radii 1d imaging and tails -Bose-Einstein correlations of charged pions in 200 GeV p+p collisions comparisons with Au+Au m t and N part scaling of 3d HBT radii 1d imaging and tails - Squeezed particle-antiparticle correlations (see M. Nagy’s subsequent talk for details) ‏

2 HBT nomenclature x The source S can be directly recovered with imaging Make assumptions about the source adapted from Annu. Rev. Nucl. Part. Sci : Detector Simplified for identical particles or Bose-Einstein Enhancement at low relative momentum q

HBT signal of 1st order phase transitions, uses R out /R side (m t, √s NN ) H. Petersen, QM 2009 talk: HG= hadron gas EoS +hydro BM= bag model EoS + hydro CH= chiral EoS with CP+hydro arXiv: Comment: Rischke's hydro NA49 HBT puzzle is not RHIC specific R out /R side sensitive to the EoS

4 Kaon interferometry: M. Gyulassy, Sandra S. Padula, PRC 41, R21 (1990) ‏ - Kaons less effected by decays of long lived resonances, than pions. - A clearer distinction between QGP formation and resonance dynamics But kaons follow m T scaling at CERN SPS: NA44 Collab, PRL 87:112301, (2001) ‏ Why kaon HBT in Au+Au at RHIC? From M. Csana’d, T. Cs., Acta Phys.Polon.Supp.1: ,2008

5 First imaging data: extended tail of pion emission in S(r) ‏ Long lived resonances? Pions have longer tail, than kaons. Hadronic rescattering? Pions larger cross sections, than kaons. Anomalous diffusion in HRC simulation: kaon’s tail is longer, than pions!(?) ‏ Phys.Rev.Lett.98:132301,2007 Why kaon imaging in Au+Au? M. Csanád et al., Braz.J.Phys.37: ,2007

At p~ 1.5 GeV/c, At p t ~ 1.5 GeV/c, contamination from pions: 4 %, from (anti)protons: 1 %. After track selection and merging cuts: 1.5 x 10 7 K + K + and 1.4 x 10 7 K - K - pairs

8 Transverse mass scaling A. Glenn QM 2009 In 200 GeV Au+Au, m T dependent HBT radii for charged kaons and pions follow the same universal m T scaling curve Particle type independent m T scaling : T. Csörgő and B.Lörstad Phys.Rev.C54: (1996)‏ PHENIX charged kaon HBT data: Phys. Rev. Lett. 103, (2009)

Squeezed particle-antiparticle correlations ‏ Back-to-back particle-antiparticle correlations: first measurements Expected to signal in-medium mass modification of hadrons For more details, see the subsequent talk of M. Nagy 20

Summary, K ± K ± in Au+Au Kaon m T and m T scaled centrality dependence consistent with pions. Kaon HBT radii scale as R HBT = p 1 N part 1/3 i.e. R HBT =0 at N part =0 Bulk production in agreement with predictions on m T scaling, and with a promising 1+1D+hydro+cascade with initial flow Significant tail in imaged K source for r>10fm Tail stronger for kaons than for pions ! Tail in pions not just from resonances! Further checks needed for other particles (protons)! 21

22 Summary:  in p+p Pion correlations in min. bias collisions for PHENIX west arm acceptance do not show significant energy momentum contamination. Measured radii: consistent with centrality extrapolation from Au+Au Plenty to look at (multiplicity dependence, jets…) ‏ 22 In Au+Au, the first preliminary back-to-back particle-antiparticle correlations were measured. See M. Nagy’s subsequent talk.
