Probing scalar meson structures in $χ_{c1}$ decays into pseudoscalar
and scalar    [PDF]

Qian Wang, Gang Li, Qiang Zhao

We evaluate the decay branching ratios of $\chi_{c1}\to PS$, in a quark model
parametrization scheme, where $P$ and $S$ stand for pseudoscalar and scalar
meson, respectively. An interesting feature of this decay process is that the
$c\bar{c}$ annihilate via the pQCD hair-pin diagram is supposed to be dominant.
Hence, this decay process should be sensitive to the quark components of the
final-state light mesons, and would provide a great opportunity for testing the
mixing relations among the scalar mesons, i.e. $f_0(1370)$, $f_0(1500)$ and
$f_0(1710)$, by tagging the final state pseudoscalar mesons.
