Description
Pi-Pi scattering is investigated for the first time for N_f=2+1+1
dynamical quark flavours using Wilson twisted mass fermions. Lüschers
finite size method is used to relate energy shifts in finite volume
to scattering quantities like the scattering length in the I=2
channel. The computation is performed at several pion masses and lattice
spacings utilysing the stochastic LapH method, which is applied to spatial lattice volumes as large as 48^3.
