摘要:

本文讨论了在MILC asqtad晶格上用改进的交错费米子计算$B_K$的有限体积误差。使用GPU,我们现在能够使用次领先阶(NLO)交错SU(2)手征微扰理论进行外推,包括由π环引起的有限体积校正。我们发现,FV拟合的影响是非常小的,在连续极限的0.5%的移动。

英文摘要:

We discuss finite volume errors in our calculations of $B_K$ using improved staggered fermions on the MILC asqtad lattices. Using GPUs, we are now able to extrapolate using next-to-leading order (NLO) staggered SU(2) chiral perturbation theory including the finite volume corrections arising from pion loops. We find that the impact of FV fitting is very small, giving a 0.5% shift in the continuum limit.
