Improved interpolating fields for hadrons at non-zero momentum    [PDF]

Michele Della Morte, Benjamin Jaeger, Thomas Rae, Hartmut Wittig

We generalize Gaussian/Wuppertal smearing in order to produce non-spherical wave functions. We show that we can achieve a reduction in the noise-to-signal ratio for correlation functions of certain hadrons at non-zero momentum, while at the same time preserving a good projection on the ground state.
