Download or read book Study of The 1 And 2 Charmonium States Formed in anti P p Annihilations written by and published by . This book was released on 1998 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors report on a study of the 3P1(?1) and 3P2(?2) states of charmonium formed in antiproton-proton annihilations. An energy scan through the resonances, performed with a very narrow momentum-band beam of antiprotons intersecting a hydrogen jet target, enables them to perform very precise measurements of the mass and the total width of the two resonances. From their measurement of the quantity?(R → {anti p}p) × BR(R → J/??) × BR(J? → ee−), using known branching ratios, the authors obtain:?(?1 → {anti p}p) = (69 ± 13) eV;?(?2 → {anti p}p) = (180 ± 31) eV.

Book excerpt: 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, [chi][sub 1], [chi][sub 2] and a new measurement of the[psi] mass are presented.
