Pt Study of the P violation Signals

Vasily Dzhordzhadze

Parity Group Teleconference

January 29, 2009

Goal of the Study

  • Pt dependence of the signal

  • Pt cut : 0.15 – 2.0 GeV/c

  • Pt cut : 0.10 – 100. GeV/c

  • Compare signal for different Pt regions

  • 0.15 – Ptb to Ptb -2.0 GeV/c

  • Ptb = 0.4, 0.5, 0.6 and 0.7 GeV/c

2


Run 4, AuAu 200 GeV, 14 M events

Cut: 0.15<Pt<2.0 GeV/c

Pt, GeV/c














Summary

  • In experiment no signal for Pt < 0.6 GeV/c

  • Strong signals for Pt> 0.6 GeV/c

  • Pt < 0.6 GeV/c ~ 40% of total stat. - no Signal

  • Pt > 0.6 GeV/c ~ 14% of total stat. - stromg deviations

  • Cross regions ~ 46% of total stat. - not analysed

  • Independent confirmation of the observation is needed!

  • An Explanation ?
