Predicting $B^{()}\bar D{}^{()}$ states from a reanalysis of lattice QCD data

We reanalyze the lattice QCD data for the isoscalar $\bar b\bar c ud$ systems with $J^P=0^+$ and $1^+$ at $m_{\pi}\simeq 220$ MeV, incorporating both short- and long-range interactions constrained by heavy-quark spin and chiral symmetries. Using the interaction fitted to the lattice results, we predict a spectrum of is...

The $D\pi$ and $D^*\pi$ femtoscopy puzzle

We present a relativistic momentum-space framework for femtoscopic correlation functions including strong and Coulomb interactions in coupled channels. The approach extends the Vincent--Phatak prescription to the three-dimensional Bethe--Salpeter equation, combining a fully relativistic treatment with the correct Coulo...

The new LHCb beauty-strange state as the bottom partner of the $D_{s0}^*(2317)$: a LQCD constrained coupled-channel chiral analysis

The LHCb Collaboration has observed a narrow state in the $\bar{B}_s^0\pi^0$ spectrum, about 74 MeV below the $B^-K^+$ threshold, which is the natural candidate for the bottom partner of the $D_{s0}^*(2317)$. Such a state had been predicted as a $\bar{B}K$ bound state by unitarized heavy-meson chiral perturbation theor...
