DK and ππ Scattering from Lattice QCD

Antonio Cox
2019
Lüscher's formalism and its generalisations enables the access of scattering properties of particles by perfoming numerical computations on the lattice. The formalism is applied to ππ, Kπ, DK and DK* elastic scattering with angular momentum-parity combinations of 0⁺, 1⁺, 1⁻ and 1⁻, respectively. Masses and couplings of the resonances and bound states which couple to these channels are determined. The weak decay constants of the scalar and axialvector charmed-strange bound states are also
