Hybrid exotic meson with J = 1−+ in AdS/QCD
نویسندگان
چکیده
We investigate the hybrid exotic meson with J = 1−+ within the framework of an AdS/QCD model. Introducing a holographic field dual to the operator for hybrid exotic meson, we obtain the eigen-value equation for its mass. Fixing all free parameters by QCD observables such as the ρ-meson mass, we predict the masses of the hybrid exotic meson. The results turn out to be 1476MeV for the ground state, and 2611MeV for the first excited one. Being compared with the existing experimental data for the π1(1400), which is known to be mπ1 = 1351± 30MeV, the present result seems to be qualitative in agreement with it. We also predict the decay constant of π1(1400): Fπ1 = 10.6 MeV.

Decay width of light quark hybrid meson from the lattice . UKQCD Collaboration
Lattice QCD with N f = 2 flavours of sea quark is used to explore the spectrum and decay of a J P C = 1 −+ spin-exotic hybrid meson. We test lattice determination of S-wave decay amplitudes at threshold using b 1 → πω where agreement with data is found. We find a hybrid meson state at 2.2(2) GeV with a partial width to πb 1 of 400(120) MeV and to πf 1 of 90(60) MeV.

We estimate the sizeable cross section for deep exclusive electroproduction of an exotic J = 1 hybrid meson in the Bjorken regime. The production amplitude scales like the one for usual meson electroproduction, i.e. as 1/Q. This is due to the non-vanishing leading twist distribution amplitude for the hybrid meson, which may be normalized thanks to its relation to the energy momentum tensor and ...

A decay width calculation for a hybrid exotic meson h, with J = 1, is presented for the channel h → πa1. This quenched lattice QCD simulation employs Lüscher’s finite box method. Operators coupling to the h and πa1 states are used at various levels of smearing and fuzzing, and at four quark masses. Eigenvalues of the corresponding correlation matrices yield energy spectra that determine scatter...

We present results for the hybrid meson spectrum produced by gluonic excitations in full QCD using Wilson fermions. For the spin-exotic mesons with J P C = 1 −+ , 0 +− , and 2 +− we find the lightest state to be 1 −+ with a mass of 1.9(2) GeV. Results obtained for orbitally excited mesons are also presented.
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...
