Abstract
Fermilab experiment E-760 studies the resonant formation of charmonium states in proton-antiproton interactions using a hydrogen gas-jet target in the Antiproton Accumulator ring at Fermilab. Precision measurements of the mass and width of the charmonium states c1,c2, a direct measurement of the width, and a new precision measurement of the J mass are presented. © 1992 The American Physical Society.File in questo prodotto:
