我们推广高斯/伍珀塔尔拖尾,以产生非球面波函数。我们表明,我们可以实现在非零动量的某些强子的相关函数的噪声信号比的减少,而在同一时间保持良好的投影在基态。
We generalise 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.
