Machine learning unveils the quark mass dependence of the pseudoscalar meson decay constants in three-flavour N $^{2}$ LO ChPT

Zejian Zhuang, Fernando Gil DomÃnguez, Fernando Gil Domínguez +1

The quark mass dependence of the pseudoscalar meson decay consntants, $f_{π}, f_{K}$ and $f_{η}$ , are determined from three-flavor N $^{2}$ LO ChPT till pion masses around $780$ MeV, near th…

Revealing the $D_{0}^{*} (2300)$ two-pole structure from lattice data and the SU(3) limit

Zejian Zhuang, Fernando Gil DomÃnguez, Raquel Molina

We perform an analysis of LQCD light - charmed (pseudoscalar) meson scattering data with UChPT for pion masses ranging from $m_{I ¨} ≃ 230$ ~MeV till the SU(3) limit, $m_Ï\simeq 7…

Pole trajectories of the $I^ (1405)$ helps establish its dynamical nature

Zejian Zhuang, Raquel Molina, Jun-Xu Lu +1

The $I^ (1405)$ has been one of the most controversial exotic baryons. If the $I^ (1405)$ possesses a two-pole molecular structure, these poles are expected to evolve differently tow…
