“…Such structure has two sources: the loop diagrams in figure 1 and the ππ FSI. To see this, we show as the red dashed curve in the right panel of figure 3 meson (5750 ± 17 ± 19) MeV [66] and slightly larger than the more recent lattice determination of (5741 ± 14) MeV [67]. So far, the only experimentally observed B s1 meson is the B s1 (5830) 0 [3], which is the bottom partner of the D s1 (2536) and not of the one discussed here.…”

The internal structure of the charm-strange mesons $D_{s0}^*(2317)$ and $D_{s1}(2460)$ are subject of intensive studies.Their widths are small because they decay dominantly through isospin-breaking hadronic channels $D_{s0}^*(2317)^+\to D_s^+\pi^0$ and $D_{s1}(2460)^+\to D_s^{*+}\pi^0$.The $D_{s1}(2460)$ can also decay into the hadronic final states $D_s^+\pi\pi$, conserving isospin. In that case there is, however, a strong suppression fromphase space.We study the transition $D_{s1}(2460)^+\to D_s^+\pi^+\pi^-$ in the scenario that the $D_{s1}(2460)$ is a $D^*K$ hadronic molecule. The $\pi\pi$ final state interaction is taken into account through dispersion relations. We find that the ratio of the partial widths of the $\Gamma(D_{s1}(2460)^+\to D_s^+\pi^+\pi^-)/\Gamma(D_{s1}(2460)^+\to D_s^{*+}\pi^0)$ obtained in themolecular picture is consistent with the existing experimental measurement.More interestingly, we demonstrate that the $\pi^+\pi^-$ invariant mass distribution shows a double bump structure,which can be used to disentangle the hadronic molecular picture from the compact state picture for the $D_{s1}(2460)^+$.Predictions on the $B_{s1}^0\to B_s^0\pi^+\pi^-$ are also made.

We discuss the main issues in dealing with heavy quarks on the lattice and shortly present the different approaches used. We discuss a selection of computations covering first the b-quark mass and the $$B_{(s)}$$ B ( s ) meson decay constants as the consolidated results (neglecting isospin breaking corrections). In the second part, we consider recent calculations of form factors for tree-level semileptonic decays with emphasis on the tensions between the results produced by different collaborations. We propose benchmark quantities and tests suited to investigate the origin of such tensions. Finally, we review computations of the bag parameters parameterising neutral meson mixing and provide an overview on a few recent developments in the field.

We generalize the relativistic field-theoretic three-particle finite-volume scattering formalism to describe generic DDπ systems in the charm C = 2 sector. This includes the isospin-0 channel, in which the recently discovered doubly-charmed tetraquark Tcc(3875)+ is expected to manifest as a pole in the DDπ → DDπ scattering amplitude. The formalism presented here can also be applied to lattice QCD settings in which the D* is bound and, in particular, remains valid below the left-hand cut in DD* scattering, thus resolving an issue in previous analyses of lattice-determined finite-volume energies.
