The drift chamber and Cherenkov detector provide clean samples of identified π ± , K ± , and p / ¯ p over a wide range of momenta. Since the center-of-mass energy is below the threshold to produce a B ¯¯¯ B pair, with B a bottom-quark meson, these data represent a pure e + e − → q ¯ q sample with four quark flavors, and are used to test QCD predictions and hadronization models. Combined with measurements at other energies, in particular at the Z 0 resonance, they also provide precise constraints on the scaling properties of the hadronization process over a wide energy range.26 p.application/pdfeng(c) American Physical Society, 2013Física de partículesExperimentsParticle physicsExperimentsinfo:eu-repo/semantics/article6290142019-04-08info:eu-repo/semantics/openAccess
