D-wave charmonium production in B decays

چکیده
The calculation of D-wave charmonium prodution rates in B meson deacys under the NRQCD factorization formalism is presented. We find that inclusion of the color-octet contributions permits us to detect the D-wave charmonium states in B decays at present experimental facilities. The same amount signals of 2 D-wave state as that of ψ could be observed at LEP and CESR. We also predict the relative production rates for four D-wave states are δ : δ 1 : δ c 2 : δ c 3 = 2.5 : 3 : 5 : 7, where δ , δ 1, δ c 2, δ c 3 represent respectively the 2, 1, 2, 3 states. PACS number(s): 12.25.Hw, 12.38.Lg, 14.40.Nd

A Crucial Test for Color-octet Production Mechanism in Z Decays
The direct production rates of D-wave charmonia in the decays of Z is evaluated. The color-octet production processes Z → DJ(cc̄)qq̄ are shown to have distinctively large branching ratios, the same order of magnitude as that of J/ψ prodution, as compared with other D-wave charmonium production mechanisms. This may suggest a crucial channel to test the color-octet mechanism as well as to observe t...
متن کاملGluon Fragmentation to Dj Quarkonia and Test of Color-octet Production Mechanism
We report the recent progress in the studies of D-wave heavy quarkonia production from gluon fragmentation at the Tevatron and in Z decays, and the D-wave charmonia production in B decays. We show that the color-octet contributions are of crucial importance to the production of D-wave quarkonia. Signals, as strong as that for J/ψ and ψ′, should be seen for the D-wave charmonium in the processes...
متن کاملInclusive S-wave charmonium productions in B decays.
The inclusive S−wave charmonium production rates in B decays are considered using the Bodwin-Braaten-Lepage (BBL) approach, including the relativistic corrections and the color-octet mechanism suggested as a possible solution to the ψ ′ puzzle at the Tevatron. We first consider relativistic and radiative corrections to J/ψ → ee and J/ψ → Light Hadrons (LH), in order to determine two nonperturba...

Spin effects in B c → X c¯ c π(ρ) decays. Abstract The two-particle hadronic decays of B c meson into S-wave and P-wave charmonium states X c¯ c are considered in the framework of hard gluon exchange model. It is shown that decay width of B c meson into S-wave charmonium states doubly exceeds one for P-wave states. In compare with the previous estimations we predict the enhancement by 8 % the b...
