摘要:

我们提出了新的高统计结果的核子形状因子在π介子质量约290,350,500,和600 MeV的畴壁价夸克的混合行动上改进的交错海。我们执行手性适合矢量和轴向形状因子,并将我们的结果与实验进行比较。

英文摘要:

We present new high-statistics results for nucleon form factors at pion masses of approximately 290, 350, 500, and 600 MeV using a mixed action of domain wall valence quarks on an improved staggered sea. We perform chiral fits to both vector and axial form factors and compare our results to experiment.
