Mass spectrum of 1 � exotic mesons using the Maximum Entropy Method
نویسندگان
چکیده
Time correlation functions for an exotic hybrid meson, J PC £ 1¤ ¦ ¥ , are analyzed using the maximum entropy method (MEM). The MEM analysis provides both ground and excited state energies. Both the location and strength of each spectral mass density peak are determined when a simulated annealing process is employed with the MEM analysis. We extract ground and excited states of about 1.4, 1.6, and 2.2 GeV when extrapolating to the physical pion mass.

The color anti-triplet triquark qq̄q̄ is considered as a compact component in the tetraquark structure cqq̄q̄ of exotic Ds mesons. We discuss the mass spectrum and the flavor mixing of the triquarks by using the instanton induced interaction and the one-gluon exchange potentials. As a characteristic property of the triquark, we investigate the isospin violation. It is shown that the flavor 3 (isosi...

متن کاملfrom lattice QCD
Time correlation functions of a hybrid exotic meson operator, with J = 1, generated in quenched lattice QCD are subjected to a (Bayesian) maximum entropy analysis. Five distinct spectral levels are uncovered. Their extrapolation into the physical pion mass region suggests a possible relationship to experimentally known states π1(1400) and π1(1600), and also to a state in the 2 GeV region carryi...

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.
