P 1 charmonium state decay into p p̄ in QCD models including constituent quark mass corrections
Stimulated by the experimental observation, made by the E760 Collaboration at Fermilab, of the P1 state of charmonium resonantly formed in p p̄ annihilation, we perform a calculation of the decay width for the P1 → p p̄ process. To this end, we employ a phenomenological model which adds constituent quark mass corrections to the usual massless QCD models for exclusive processes. For massless model...
متن کامل0 Spin effects in B c → X cc̄ π ( ρ ) decays
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 P-wave charmonium states exceeds one for S-wave states. In compare with the previous estimations we predict the enhancement by factor ∼ 2 the b...

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...

Using the fact that the c-quark inside a charmonium moves with a small velocity v in the charmonium rest-frame, one can employ an expansion in v to study decays of charmonia and results at the leading order for χc0,2 → γγ exist in the literature. We study corrections at the next-to-leading order in the framework of nonrelativistic QCD(NRQCD) factorization. The study presented here is different ...
متن کاملCombination of Colour Favoured and Colour
In this research we described the effective Hamiltonian theory and applied this theory to the calculation of current-current (Q1,2) and QCD penguin (Q3,…,6) c quark decay rates. We calculated the decay rates of semileptonic and hadronic of charm quark in the effective Hamiltonian theory. We investigated the decay rates of D meson decays according to Spectator Quark Model (SQM) for the calculati...
