16. Weak Decays of Charmed Baryons from LQCD

Prof. Wei Wang (Shanghai JiaoTong University)

51. Valence parton distribution of pion from lattice QCD at physical point

Dr 翔 高

31/10/2021, 14:30

We present the first lattice calculation of pion valence parton distribution using matching formula at NNLO level. We use the Wilson-Clover fermion on three 2+1 flavor HISQ ensembles of lattice spacings a = 0.04, 0.06 and 0.076 fm, with two pion mass including the physical one. Two unitary Domain-Wall calculations at physical point are also presented. This allows us to control the continuum...

17. Lattice QCD Calculation of TMD Soft Function Through Large-Momentum Effective Theory

18. Distribution amplitudes from lattice QCD

Dr 俊 华 (Shanghai Jiao Tong University)

31/10/2021, 16:00

We present the first lattice QCD calculation of the distribution amplitudes of longitudinally and transversely polarized vector mesons K∗ and φ using large momentum effective theory. We use the clover fermion action on three ensembles with 2+1+1 flavors of highly improved staggered quarks (HISQ) action, generated by MILC collaboration, at physical pion mass and {0.06, 0.09, 0.12} fm lattice...

21. Collins-Soper kernel from transverse momentum-dependent wave functions in LaMET

旻寰 楚 (Shanghai Jiao Tong University)

31/10/2021, 16:30

In this work we present the transversity $b_{\perp}$-dependence Collins-Soper kernel extracted from pion transverse momentum dependent wave functions in the framework of large momentum effective theory from lattice QCD. We use clover fermion action with $2 + 1 + 1$ flavors of highly improved staggered quarks (HISQ), generated by MILC Collaboration. A single ensemble is used, with lattice...

27. Correlated Dirac Eigenvalues and Axial Anomaly in Chiral Symmetric QCD

Dr 瑜 张

31/10/2021, 16:50

In this talk I will present the novel relations between the quark mass derivatives [$\partial^n \rho(\lambda,m_l)/\partial m_l^n$] of the Dirac eigenvalue spectrum and the $(n+1)$-point correlations among the eigenvalues. Using these relations we present lattice QCD results for $\partial^n \rho(\lambda,m_l)/\partial m_l^n$ ($n=1, 2, 3$) for $m_l$ corresponding to pion masses...
