Relations among pionic decays of spin-1 mesons from an SU(4)$\times$U(1) emergent symmetry in QCD

Hiroki Nishihara, Masayasu Harada

Motivated by recent results by lattice analysis, we assume that the spin-1 mesons of $\left(\rho ,\omega ,a_1,{\rho }^{\prime },{\omega }^{\prime },b_1,f_1,h_1\right)$ make a representation of $16$ of U(4)…
