Strong decays of the higher isovector scalar mesons

Abstract

Under the assignment of $a_0(1450)$ as the ground isovector scalar meson, the strong decays of $a_0(1950)$ and $a_0(2020)$ are evaluated in the ${}^3{P}_0$ model. Our calculations suggest that $a_0(1950)$ and $a_0(2020)$ can be regarded as the same resonance referring to $a_0(3^3{P}_0)$. The masses and strong decays of $a_0(2^3{P}_0)$ and $a_0(4^3{P}_0)$ are also predicted, which can be useful in the search for radially excited scalar mesons in the future.
