In this paper, we discuss the significance and prospect for the newly
discovered a0(1710)[a0(1817)] resonance state at BESIII experiment, in which
they reported the observation of a scalar meson of spin-parity JP=0+ with
isospin I=1, branded as a0β(1817). This state may be the same particle as
the a0β(1710) observed by the BaBar experiment earlier. As early as 2008, we
found that f0(1710) can be regarded as a KβKΛβ molecular state based
on the chiral unitary theory, and there is a partner state a0β(1710) with an
isospin I=1. Our theoretical prediction based on this picture is in good
agreement with the latest BESIII data, which further supports the molecular
state picture of a0β(1710)[a0β(1817)]. If it is indeed the isospin partner
state of f0β(1710), this would rule out f0β(1710) as a glueball candidate.
This paper briefly reviews the relevant theoretical studies and suggests new
experiments to further examine the nature of a0β(1710)[a0β(1817)].Comment: typos corrected. 6 pages,4 figures, to be published as a
