Description

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 featuring pion masses ranging from about 230 MeV to 450 MeV at three values of the lattice spacing. The elastic scattering length $a_0$ is calculated at several values of the bare strange quark and light quark masses. Chiral extrapolations to the physical point are presented and compared to other lattice results.
