Study of the pion-mass dependence of $\rho$-meson properties in lattice QCD

Kang Yu, Yan Li, Jia-Jun Wu +2

We collect spectra extracted in the $I=\ell =1$ $\pi \pi$ sector provided by various lattice QCD collaborations and study the $m_{\pi }$ dependence of $\rho$-meson properties using Hamiltonian E…
