Diffractive Vector Mesons in Dis: Meson Structure and Qcd *
which is accessible experimentally at finite (γ.V ) momentum transfer ∆. Furthermore, the decays of VM’s are self-analyzing and azimuthal correlations of (e, e), (p, p) and decay planes and polar decay angle distributions allow to reconstruct the full set of helicity amplitudes Aνμ, which allows to probe the mechanism of generalized CS in full complexity. The new numerical results reported here...
متن کاملHybrid mesons from lattice QCD
Recent lattice simulation studies of heavy-quark hybrid mesons in which the quark and antiquark are bound together by an excited gluon field are summarized. Hybrid mesons are states in which a valence quark and an antiquark are bound by an excited gluon field. Interest in such states has been recently sparked by observations of resonances with exotic 1 quantum numbers[1]. In fact, the proposed ...

متن کاملExotic Mesons in Quenched Lattice Qcd 1
Since gluons in QCD are interacting fundamental constituents just as quarks are, we expect that in addition to mesons made from a quark and an antiquark, there should also be glueballs and hybrids (bound states of quarks, antiquarks and gluons). In general, these states would mix strongly with the conventional qq mesons. However, 1 Submitted to Physical Review D. they can also have exotic quant...
متن کاملDiffractive leptoproduction of vector mesons in QCD.
We demonstrate that the distinctive features of the forward differential cross section of diffractive leptoproduction of a vector meson can be legitimately calculated in perturbative QCD in terms of the light-cone qq̄ wave function of the vector meson and the gluon distribution of the target. In particular, we calculate the Q2 and nuclear dependence of the diffractive leptoproduction of vector m...
