The probability distribution of neutral pion fraction from independent domains of disoriented chiral condensate is characterized. The signal for the condensate is clear for a small number of domains but is greatly reduced for more than three. Typeset using REVTEX 1 There has been much interest recently in the possible production of a disoriented chiral condensate in high energy hadronic or heav...

This talk presents issues pertaining to the quark structure of the pion within QCD, both from the theoretical and from the experimental point of view. We review and discuss the pion-photon transition form factor and the pion’s electromagnetic form factor vs. corresponding experimental data from the CLEO Collaboration and the JLab. We also examine the extent to which recent high-precision lattic...

The Transition Radiation Detector (TRD) of the ALICE experiment at LHC is designed to provide electron/pion identification and tracking of all charged particles [1]. The TRD will supplement the TPC electron/pion identification by a pion rejection factor of the order of 100 at momenta above 1 GeV/c, allowing precision measurements of quarkonia. Sophisticated on-detector electronics [2] is design...

The phases of quantum interference effects in charged lepton production by neutrinos (neutrino oscillations) following pion decay at rest and in flight, muon decay and nuclear β−decay at rest as well as for ‘muon oscillations’ following pion decay at rest and in flight are calculated. The same phase is found for neutrino and muon oscillations following pion decay at rest. The results found disa...

With the aim to study spin dependence of pion production near threshold, an internal target facility and a forward detector have been installed in the Cooler synchrotron ring at IUCF. The detector system comprises scintillators and wire chambers. The target consists of a thin-walled open-ended storage cell into which polarized atomic hydrogen is injected. Using a stored and cooled, polarized pr...

Within the one-pion exchange model we calculate the near-threshold η ′ production from pp collisions including the final state interaction between the protons. Since the description of the data is quite well we conclude that η, ρ or ω exchange currents either play no role or cancel each other to a large extent in this reaction. Recently the COSY-11 [1] and SPES III [2] Collaborations have measu...
