Revealing the $D_0^{\ast }(2300)$ two-pole structure from lattice data and the SU(3) limit

Zejian Zhuang, Fernando Gil Domínguez, Raquel Molina

We perform an analysis of LQCD light - charmed (pseudoscalar) meson scattering data with UChPT for pion masses ranging from $m_{\pi }\simeq 230$~MeV till the SU(3) limit, $m_π\simeq 700…
