-0.1 < ssxptar < 0.1

-0.1 < ssyptar <0.1

Particle Identification (PID)

HMS:

(haero_po+haero_ne) < 1 -8 ns < coincidence time < -6.5 ns 1.05 < missing mass < 1.25

SOS

Graphs

  • Missing mass vs. coincidence time

  • HMS aerogel with strict cuts to eliminate events that give a signal (pions at this momentum)

  • coincidence time vs missing mass with no aerogel cherenkov signal.

  • HMS aerogel spectrum

  • SOS acceptance momentum

  • HMS acceptance momentum

  • HMS acceptance horizontal

  • HMS acceptance vertical

  • calculated missing mass vs. Analyzer - works!

FPI-2 experiment

  • cointime

  • missmass

  • cointime vs missmass without cuts

  • cointitme vs missmass with cuts

  • kaon momenta distribution

  • electron momenta distribution
