“…The LHCb experiment should be able to see the remaining two states (0 + and 1 + ), which are expected to decay into s-wave states by emitting either a photon or a π 0 [15]. On the theory side there are a number of phenomenological model and EFT mass determinations [16,17,18,19,20,21,15,5,22,23], a determination using Unitarized EFT based on low energy constants extracted from lattice QCD simulations [24], and some lattice QCD calculations in the static limit [25,26,27,28,29].

We determine the spectrum of B s 1P states using lattice QCD. For the B s1 (5830) and B * s2 (5840) mesons, the results are in good agreement with the experimental values. Two further mesons are expected in the quantum channels J P = 0 + and 1 + near the BK and B * K thresholds. A combination of quark-antiquark and B ( * ) meson-Kaon interpolating fields are used to determine the mass of two QCD bound states below the B ( * ) K threshold, with the assumption that mixing with B ( * ) s η and isospin-violating decays to B ( * ) s π are negligible. We predict a J P = 0 + bound state B s0 with mass m B s0 = 5.711(13)(19) GeV. With further assumptions motivated theoretically by the heavy quark limit, a bound state with m B s1 = 5.750 (17)(19) GeV is predicted in the J P = 1 + channel. The results from our first principles calculation are compared to previous model-based estimates.

The results of our numerical investigation have also been positive [3]. The variation of the renormalised anisotropy measured from the dispersion relations of pseudoscalar and vector mesons was shown to be mild over a range of quark masses from strange to charm.…”

This mass-dependence of ξ in the dynamical theory may be a discretisation effect and is under investigation.…”
