چکیده
We study in this paper the possible signals of a pion string associated with the QCD chiral phase transition in LHC Pb Pb collision at energy √ s = 5.5 A TeV. In terms of the Kibble-Zurek mechanism we discuss the production and evolution of the pion string. The pion string is not topologically stable, its decay gives rise to the neutral pions and the sigma mesons which decay into pions. We estimate the numbers of the pions and their momentum distribution produced by the pion string decay. Typeset using REVTEX

We study the possible signals of a pion string associated with the QCD chiral phase transition in LHC Pb Pb collision at energy √ s = 5.5 TeV. In terms of the Kibble-Zurek mechanism we discuss the production and evolution of the pion string. The pion string is not topologically stable, it decays into neutral pions and sigma mesons which in turn decay into pions. We estimate the numbers of the p...

Here I present some recent results of the DØ and CDF collaborations on Large Extra Dimensions , Z ′ , and SUSY searches. The experiments examine events produced by proton-antiproton collisions, with an integrated luminosity of approximately 200 events/pb per experiment. Unfortunately , despite careful searches, no new signals of physics beyond the standard model were observed. Therefore, I pres...

The production of baryon and mesons in the RHIC heavy-ion experiments has received a lot of attention lately. Although not widely known, the pp data measured concurrently with heavy ion collisions do not find a convincing explanation in terms of simple models. We present the results of an afterburner to Pythia and Hijing event generators, simulating radial flow which seems to qualitatively expl...
