Observation Of 1(-)0(-) Final States From Psi(2s) Decays And E(+)E(-) Annihilation
PHYSICAL REVIEW LETTERS(2005)
摘要
Using CLEO data collected from CESR e(+)e(-) collisions at the psi(2S) resonance and nearby continuum at roots = 3.67 GeV, we report the first significantly nonzero measurements of light vector-pseudoscalar hadron pair production (including rhopi, omegapi, rhoeta, and K-*0(K) over bar (0)) and the pi(+)pi(-)pi(0) final state, both from psi(2S) decays and direct e(+)e(-) annihilation.
