Production of orbitally excited vector mesons in diffractive DIS
Within the kt-factorization framework, we study diffractive production of orbitally excited vector mesons and compare it with the production of radial excitations, focusing on the ρ(1450)/ρ(1700) case. At small Q2, orbital excitation of light quarkonia is found to dominate over radial excitations in diffractive production. We predict strong suppression of the production of orbital excitations b...

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 کاملProduction of spin-3 mesons in diffractive DIS
We calculate the amplitudes of J = 3−− meson production in diffractive DIS within the kt-factorization approach, with a particular attention paid to the ρ3(1690) meson. We find that at all Q2 the ρ3(1690) production cross section is 2–5 times smaller than the ρ(1700) production cross section, which is assumed to be a pure D-wave state. Studying σL and σT separately, we observe domination of ρ3 ...
متن کاملObservation of orbitally excited B(s) mesons.
We report the observation of two narrow resonances consistent with states of orbitally excited (L=1) B_(s) mesons using 1 fb;(-1) of pp[over ] collisions at sqrt[s]=1.96 TeV collected with the Collider Detector at Fermilab II detector at the Fermilab Tevatron. We use two-body decays into K- and B+ mesons reconstructed as B(+)-->J/psiK(+), J/psi-->mu(+)mu(-) or B(+)-->D[over ](0)pi(+), D[over ](...
متن کاملProperties of Orbitally Excited Heavy-Light Mesons
Orbitally excited heavy-light mesons are potentially important as tools for tagging the flavors and momenta of ground-state pseudoscalars detected through weak decays. We use heavy-quark symmetry supplemented by insights gleaned from potential models to estimate masses and widths of p-wave B, Bs, and Ds mesons. We generalize these results to higher excitations. PACS numbers: 14.40.Jz, 13.25.+m,...
