Exclusive radiative production of fully-charmed tetraquarks at B factory

چکیده
We apply a novel factorization formula recently developed within NRQCD framework to analyze the exclusive production of fully-charmed tetraquark T4c plus hard photon at super B factory. For simplicity, in this work we have concentrated on 0++ and 2++ associated with photon. With some rough estimates about unknown nonperturbative matrix elements simplified diquark-antidiquark model, predict rates these types channels s=10.58 GeV also assess their observation prospect Belle 2 experiment.

Exclusive Radiative B Meson Decays
We have investigated exclusive, radiative B meson decays to charmless mesons (ρ, ω, φ, K(892), K 2 (1430)) in 9.7× 106 BB̄ decays accumulated with the CLEO detector. The B → K(892)γ branching fractions are determined to be B(B0 → K∗0(892)γ) = (4.55 +0.72 −0.68 ± 0.34)×10−5 and B(B+ → K∗+(892)γ) = (3.76 +0.89 −0.83 ± 0.28)×10−5. We have searched for CP asymmetry in B → K(892)γ decays and measure ...
متن کاملFactorization in exclusive semileptonic radiative B decays
We derive a new factorization relation for the semileptonic radiative decay B → πlνγ in the kinematical region of a slow pion |~ pπ | ∼ Λ and an energetic photon Eγ ≫ Λ, working at leading order in Λ/mb. In the limit of a soft pion, the nonperturbative matrix element appearing in this relation can be computed using chiral perturbation theory. We present a phenomenological study of this decay, w...
متن کاملCharmed Hadron Production at RHIC†
To extract information about polarized gluon distribution in the proton, charmed hadron, actually Λc , productions at RHIC experiment are studied. We found that the spin correlation asymmetry between the initial proton and the produced Λc is enable us to distinguish parameterization models of polarized gluons. † Talk presented by K. OHKUMA at 3rd Circum-Pan-Pacific Symposium on “High Energy Spi...
متن کاملHow to Search for Doubly Charmed Baryons and Tetraquarks
Possible experimental searches of doubly charmed baryons and tetraquarks at fixed target experiments with high energy hadron beams and a high intensity spectrometer are considered here. The baryons considered are: Ξ+cc (ccd), Ξ cc (ccu), and Ω + cc (ccs); and the tetraquark is T (ccūd̄). Estimates are given of masses, lifetimes, internal structure, production cross sections, decay modes, branchi...
متن کاملProduction of excited charmed mesons at LEP
Studies of the production of orbitally excited charmed and charmed strange mesons in eecollisions, performed by the LEP collaborations are reviewed. Measurements of the production rates of orbitally excited charmed mesons in semileptonic b decays are presented. Searches for charmed meson radial excitations are also briefly discussed.
