Strong decays of the higher isovector scalar mesons

Under the assignment of a0(1450) as the ground isovector scalar meson, the strong decays of a0(1950) and a0(2020) are evaluated in the P03 model. Our calculations suggest that a0(1950) and a0(2020) can be regarded as the same resonance referring to a0(3P03). The masses and strong decays of a0(2P03)...

Description
Summary:Under the assignment of a0(1450) as the ground isovector scalar meson, the strong decays of a0(1950) and a0(2020) are evaluated in the P03 model. Our calculations suggest that a0(1950) and a0(2020) can be regarded as the same resonance referring to a0(3P03). The masses and strong decays of a0(2P03) and a0(4P03) are also predicted, which can be useful in the search for radially excited scalar mesons in the future.
