Abstract Elastic S-wave scattering of a charm meson with a light pseudoscalar meson in J P = 0+ is investigated in the flavour 3 ¯ $$ \overline{\textbf{3}} $$ , 6 and 15 ¯ $$ \overline{\textbf{15}} $$ sectors at the SU(3) f flavour point using latt

Abstract The coupling of various charmonium mesons to a photon is studied using lattice QCD, giving access to radiative form factors and transitions, and probing the mesons’ structure. Methods are developed which allow the robust determination of a

Abstract Isospin-1/2 Dπ scattering amplitudes are computed using lattice QCD, working in a single volume of approximately (3.6 fm)3 and with a light quark mass corresponding to m π ≈ 239 MeV. The spectrum of the elastic Dπ energy region is compu

Abstract Elastic scattering amplitudes for I = 0 DK and I = 0, 1 D K ¯ $$ D\overline{K} $$ are computed in S, P and D partial waves using lattice QCD with light-quark masses corresponding to m π = 239 MeV and m π = 391 MeV. The S-waves contain int

Abstract We present the first determination of ρπ scattering, incorporating dynamically-coupled partial-waves, using lattice QCD, a first-principles numerical approach to QCD. Considering the case of isospin-2 ρπ, we calculate partial-wave amplit

Abstract We present a general class of operators resembling compact tetraquarks which have a range of colour-flavour-spin structures, transform irreducibly under the symmetries of the lattice and respect other relevant symmetries. These constructions

Immune responses to the gonococcus after natural infection ordinarily result in little immunity to reinfection, due to antigenic variation of the gonococcus, and redirection or suppression of immune responses. Brinton and colleagues demonstrated that

The quark model was formulated in 1964 to classify mesons as bound states made of a quark–antiquark pair, and baryons as bound states made of three quarks. For a long time all known mesons and baryons could be classified within this scheme. Quantum

We present the first determination of the hadronic decays of the lightest exotic $J^{PC}=1^{-+}$ resonance in lattice QCD. Working with SU(3) flavor symmetry, where the up, down and strange quark masses approximately match the physical strange-quark
