摘要

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 P 0 3 model. Our calculations suggest that a 0 ( 1950 ) and a 0 ( 2020 ) can be regarded as the same resonance referring to a 0 ( 3 P 0 3 ) . The masses and strong decays of a 0 ( 2 P 0 3 ) and a 0 ( 4 P 0 3 ) are also predicted, which can be useful in the search for radially excited scalar mesons in the future.
