Nonperturbative renormalization of asymmetric staple-shaped operators in twisted mass lattice QCD
Constantia Alexandrou, Simone Bacchio, Krzysztof Cichy +8
Staple-shaped Wilson line operators are necessary for the study of transverse momentum-dependent parton distribution functions (TMDPDFs) in lattice QCD and beyond. In this work, we…
First-principle calculation of decay width from lattice QCD
Yu Meng, Xu Feng, Chuan Liu +2
We perform a lattice QCD calculation of the decay width using a model-independent method that requires no momentum extrapolation of the off-shell form factors. This meth…
Lattice QCD Study of Transverse-Momentum Dependent Soft Function
Yuan Li, Shi-Cheng Xia, Constantia Alexandrou +9
In this work, we perform a lattice QCD study of the intrinsic, rapidity-independent soft function within the framework of large momentum effective theory. The computation is carrie…
Field sparsening for the construction of the correlation functions in lattice QCD
Yuan Li, Shi-Cheng Xia, Xu Feng +2
Two field-sparsening methods, namely the sparse-grid method and the random field selection method, are used in this paper for the construction of the 2-point and 3-point correlatio…
Ward Identity of the Vector Current and the Decay Rate of in Lattice QCD
Chuan Liu, Yu Meng, Ke-Long Zhang
Using a recently proposed method arXiv:1910.11597 (Yu Meng et al.), we study the two-photon decay rate of using two twisted mass gauge ensembles with lattice spacings…
A Lattice Study of the Two-photon Decay Widths for Scalar and Pseudo-scalar Charmonium
Ying Chen, Ming Gong, Ning Li +7
In this exploratory study, two photon decay widths of pseudo-scalar () and scalar () charmonium are computed using two ensembles of twisted mass lattice QCD ga…
