Axial-vector meson mixing in orthocharmonium decays
In the light of the recent measurement by the BES Collaboration, the two-body decays of J/ψ and ψ into an axial-vector meson and a pseudoscalar meson are analyzed in the framework of the KA − KB mixing including substantial SU(3) and G parity violations due to onephoton annihilation. A somewhat puzzling pattern of the K 1 K − decay channel can be understood with no tight constraint on the mixin...
متن کاملAxial coupling and Magnetic moment of D∗ meson
The axial coupling and the magnetic moment of D-meson or, more specifically, the couplings gD∗Dπ and gD∗Dγ , encode the non-perturbative QCD effects describing the decays D → Dπ and D → Dγ. We compute these quantities by means of lattice QCD with Nf = 2 dynamical quarks, by employing the Wilson (“clover”) action. On our finer lattice (a ≈ 0.065 fm) we obtain: gD∗Dπ+ = 20 ± 2, and gD∗0D0γ = 2.0±...
متن کاملHadronic Charmed Meson Decays Involving Axial Vector Mesons
Cabibbo-allowed charmed meson decays into a pseudoscalar meson and an axial-vector meson are studied. The charm to axial-vector meson transition form factors are evaluated in the Isgur-Scora-Grinstein-Wise quark model. The dipole momentum dependence of the D → K transition form factor and the presence of a sizable long-distance W -exchange are the two key ingredients for understanding the data ...
متن کاملUTP as an extracellular signaling molecule.
In addition to their central role in many biochemical processes, uridine nucleotides are important extracellular signaling molecules that regulate a broad spectrum of cell functions via activation of P2Y2, P2Y4, and P2Y6 receptors. Cellular release of UTP provides a mechanism for autocrine control of calcium- or protein kinase C-dependent processes.
