h/p Ratios

• Expectation (pp, e+e-):

  • h/p  1.6

• Only the case in peripheral collisions and above 5GeV

• Identified Hadrons

  • Anomalous p/p
  • Data suggests baryon vs. meson effect (from l,p vs f,p)
  • Talks: F. Matathias

• Approaches

  • E.g. recombination of quarks in a thermal phase
