论文摘要
我们报告了使用大型摩氏有效理论的质子在连续体和物理质量限制中质子的等级夸克横向分布的最新晶格QCD计算。计算以四个晶格间距$ a = \ {0.098,0.085,0.064,0.049 \} $ 〜fm和各种pion质量和$ 350 $ MEV的各种Pion Masses进行，质子MONSA最高$ 2.8 $ GEV。结果是在杂种方案中与自我恢复归一化的非扰动重新归一化的，该杂种能够适当地处理红外物理，并推断为连续体，物理质量和无限动量极限。我们还与最近对核子等夸克横向分布的全局分析进行了比较。
We report a state-of-the-art lattice QCD calculation of the isovector quark transversity distribution of the proton in the continuum and physical mass limit using large-momentum effective theory. The calculation is done at four lattice spacings $a=\{0.098,0.085,0.064,0.049\}$~fm and various pion masses ranging between $220$ and $350$ MeV, with proton momenta up to $2.8$ GeV. The result is non-perturbatively renormalized in the hybrid scheme with self renormalization which treats the infrared physics at large correlation distance properly, and extrapolated to the continuum, physical mass and infinite momentum limit. We also compare with recent global analyses for the nucleon isovector quark transversity distribution.
