Testing the stochastic LapH method in the twisted mass formulation
Abstract
We present first results using the stochastic Laplace-Heaviside (sLapH) method in the twisted mass formulation. The calculations are performed on gauge configurations provided by the European Twisted Mass (ETM) collaboration with 2+1+1 dynamical quark flavours at a single value of the lattice spacing. In particular, we compute disconnected contributions to flavour singlet pseudo-scalar mesons and compare sLapH to standard volume noise methods.
