  In-hadron condensates, defined as the scalar form factors at zero-momentum
transfer, are investigated for flavor-symmetric mesons in pseudoscalar and
vector channels under the rainbow-ladder truncation within the Dyson-Schwinger
equations framework. We confirm the efficiency of the in-hadron condensates in
describing the effects of dynamical chiral symmetry breaking from both global
and structural perspectives by comparing the meson masses, the dimensionless
in-hadron condensates, and the partial wave decompositions of in-hadron
condensates as functions of current-quark mass. From partial wave analysis, we
infer $\pi(1300)$ is a radial excitation dominated by $s$ waves and
$\rho(1450)$ is not a $p$ wave-dominated excitation. This work provides a new
insight into the studies of hadron properties with partial wave analysis for
the in-hadron condensates.
