Mass corrections in J / ψ → BB̄ decay and the role of distribution amplitudes Francesco Murgia

چکیده
We consider mass correction effects on the polar angular distribution of a baryon–antibaryon pair created in the chain decay process e−e+ → J/ψ → BB̄, generalizing a previous analysis of Carimalo. We show the relevance of the features of the baryon distribution amplitudes and estimate the electromagnetic corrections to the QCD results. 13.65.+i, 13.25.Gv, 12.38.Bx, 14.40.Gx Typeset using REVTEX

Pseuduscalar Heavy Quarkonium Decays with Both Relativistic and Qcd Radiative Corrections
We estimate the decay rates of ηc → 2γ, η c → 2γ, and J/ψ → ee, ψ → ee, by taking into account both relativistic and QCD radiative corrections. The decay amplitudes are derived in the Bethe-Salpeter formalism. The Bethe-Salpeter equation with a QCD-inspired interquark potential are used to calculate the wave functions and decay widths for these cc̄ states. We find that the relativistic correctio...
متن کاملTwo-loop Correction to the Leptonic Decay of Quarkonium
Applying asymptotic expansions at threshold, we compute the two-loop QCD correction to the short-distance coefficient that governs the leptonic decay ψ → l+l− of a S-wave quarkonium state and discuss its impact on the relation between the quarkonium non-relativistic wave function at the origin and the quarkonium decay constant in full QCD. PACS Nos.: 13.20.Gd, 12.38.Bx Quarkonium decays played ...
متن کاملP 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 کاملB → J / ψK Decays in QCD Factorization
The hadronic decays B → J/ψK(K∗) are interesting because experimentally they are the only color-suppressed modes which have been measured, and theoretically they are calculable by QCD factorization even the emitted meson J/ψ is heavy. We analyze the decay B → J/ψK within the framework of QCD factorization in the heavy quark limit. We show explicitly the scale and γ5-scheme independence of decay...
متن کاملAspects of Charmonium Physics
I review possible resolution of the J/ψ(ψ) → ρ − π puzzle based on two inputs: the relative phase between the onephoton and the gluonic decay amplitudes, and a possible hadronic excess in the inclusive nonelectromagnetic decay rate of ψ. The status of a universal large phase here is examined for its meaning and implications (including those for B-physics). Since the future of tau/charm facility...
