Masses of spin-1 mesons and dynamical chiral symmetry breaking

Bing An Li

In terms of an effective chiral theory of mesons it is shown quantitatively that in the limit of $m_{q} = 0$ , the masses of $ρ$ , $ω$ , $K^{*} (892)$ , $m_{ϕ}$ , $a_{1}$ , $f_{1} (1286)$ , $K_…

Mass relation of rho and a_{1} mesons

Bing An Li

A mass relation of rho and a_[1} mesons has been obtained from Weinberg's first sum rule and KSFR sum rule.

Revisit of Weinberg's sum rules

Bing An Li

By applying the Ward identity found by Weinberg two new relations of the amplitude of $a_{1} \to ρ π$ with other physical quantities have been found.
