Charged Particle Spectra

• Mass hypothesis
• ? ,k,p,d,t,3He
• pz mt sinh y
• 20 bins in mt (0 lt mt lt 1.0 GeV/c2)
• For a 0.1 unit slice of rapidity, successively
  add in each bin in mt
• Trajectory on dE/dx vs. momentum curve depends on
  rapidity slice and particle assumption
• 4 AGeV AuAu, ycm1.166
• ptot ?(pt0) 0.2014GeV/c
• ptot p(pt0) 1.3604 GeV/c
• ptot d(pt0) 2.7179 GeV/c
• ptot ??/mass
• Bethe-Bloch parameterization constrains fits
