Kaon-kaon scattering at maximal isospin from Nf=2+1+1 twisted mass lattice QCD
Abstract
We present results for the interaction of two kaons at maximal isospin. The calculation is based on 2+1+1 flavour gauge configurations generated by the ETM Collaboration (ETMC) featuring pion masses ranging from about 230 MeV to 450 MeV at three values of the lattice spacing. The elastic scattering length a0I=1 is calculated at several values of the bare strange quark and light quark masses. We find MK a0 =-0.397(11)(-8+0) as the result of a chiral and continuum extrapolation to the physical point. This number is compared to other lattice results.
