In this paper we have shown that the novel mass relation among the vector states, $\phi(1020)$ and $\phi(1680)$, with quantum numbers J$^{PC}=1^{--}$ and axial-vector strangeonium state $h_1(s\bar{s})$ with quantum numbers $1^{+-}$ is also valid for nonzero current quark mass. This relation predicts the mass of recently discovered $h_1(s\bar{s})$ state by the Collaboration BESIII within experimental accuracy.

Strangeonium meson spectrum in a constituent quark model

In this work, we calculate mass spectrum of the strangeonium up to the $3D$ multiplet within a nonrelativistic linear potential quark model. Furthermore, using the obtained wave functions, we also

Observation of $h_1(1380)$ in the $J/\psi \to \eta^{\prime} K\bar K \pi$ decay

Using 1.31×109  J/ψ events collected by the BESIII detector at the BEPCII e+e- collider, we report the first observation of the h1(1380) in J/ψ→η′h1(1380) with a significance of more than ten

Vector meson couplings to vector and tensor currents in extended NJL quark model

A simple explanation of the dynamic properties of vector mesons is given in the framework of extended Nambu-Jona-Lasinio quark model. New mass relations among the hadron vector resonances are

DYNAMICAL MODEL OF ELEMENTARY PARTICLES BASED ON AN ANALOGY WITH SUPERCONDUCTIVITY. PART II

Continuing the program developed in a previous paper, a "superconductive" solution describing the protonneutron doublet is obtained from a nonlinear spinor field Lagrangian. The pions of finite mass

A Schematic Model of Baryons and Mesons

If we assume that the strong interactions of baryons and mesons are correctly described in terms of the broken "eightfold way", we are tempted to look for some fundamental explanation of the

Dynamical Model of Elementary Particles Based on an Analogy with Superconductivity. II

It is suggested that the nucleon mass arises largely as a self-energy of some primary fermion field through the same mechanism as the appearance of energy gap in the theory of superconductivity. The

The three reactions pp! … 0 … 0 … 0 , … 0 … 0 · and … 0 ·· in proton-antiproton annihilation in ∞ight at 900 MeV=c are used to search for isoscalar 0 ++ and 2 ++ mesons in the mass range 1000i 2000

New Tensor Particles from pi -> e nu gamma and K -> pi e nu Decays

The inserting of antisymmetric tensor fields into the standard electroweak theory may explain the recent experiments on pi -> e nu gamma and K -> pi e nu decays. New intermediate particles can induce
