Title: 
Determination of K-pi scattering lengths at physical kinematics
Abstract: 
Scattering lengths are quantities which contain information about low energy particle scattering. I will discuss our recent calculation of K-pi scattering lengths using lattice QCD with physical pion and kaon masses. This is an improvement over existing calculations, which rely on chiral perturbation theory to reach the physical point. I will discuss how this calculation is done addressing especially new challenges that arose from using light pion and kaon masses.
