Large-Momentum Effective Theory
Xiangdong Ji, Yu-Sheng Liu, Yizhuang Liu +2
Since the parton model was introduced by Feynman more than fifty years ago, we have learned much about the partonic structure of the proton through a large body of high-energy expe…
Transverse-Momentum-Dependent Parton Distribution Functions from Large-Momentum Effective Theory
Xiangdong Ji, Yizhuang Liu, Yu-Sheng Liu
We show that transverse-momentum-dependent parton distribution functions (TMDPDFs), important non-perturbative quantities for describing the properties of hadrons in high-energy sc…
TMD Soft Function from Large-Momentum Effective Theory
Xiangdong Ji, Yizhuang Liu, Yu-Sheng Liu
We study Euclidean formulations of the transverse-momentum-dependent (TMD) soft function, which is a cross section for soft gluon radiations involving color charges moving in two c…
Matching Quasi Generalized Parton Distributions in the RI/MOM scheme
Yu-Sheng Liu, Wei Wang, Ji Xu +4
Within the framework of large momentum effective theory (LaMET), genenaralized parton distributions (GPDs) can be extracted from lattice calculations of quasi-GPDs through a pertur…
Matching the Quasi Meson Distribution Amplitude in RI/MOM scheme
Yu-Sheng Liu, Wei Wang, Ji Xu +3
The -dependence of light-cone distribution amplitude (LCDA) can be directly calculated from a quasi distribution amplitude (DA) in lattice QCD within the framework of large-mome…
Eta Decay and Muonic Puzzles
Yu-Sheng Liu, Ian C. Cloët, Gerald A. Miller
New physics motivated by muonic puzzles (proton radius and muon discrepancies) is studied. Using a light scalar boson , assuming Yukawa interactions, accounts for these mu…
Possible Beyond the Standard Model Physics Motivated by Muonic Puzzles
Yu-Sheng Liu
Recent measurements of the proton radius using the Lamb shift in muonic hydrogen are troublingly discrepant with values extracted from hydrogen spectroscopy and electron-proton sca…
Validity of the Weizsäcker-Williams Approximation and the Analysis of Beam Dump Experiments: Production of an axion, a dark photon, or a new axial-vector boson
Yu-Sheng Liu, Gerald A. Miller
Beam dump experiments have been used to search for new particles, , with null results interpreted in terms of limits on masses and coupling constants . However these li…
The Validity of the Weizsacker-Williams Approximation and the Analysis of Beam Dump Experiments: Production of a New Scalar Boson
Yu-Sheng Liu, David McKeen, Gerald A. Miller
Beam dump experiments have been used to search for new particles with null results interpreted in terms of limits on masses and coupling constants . However these limits h…
Electrophobic Scalar Boson and Muonic Puzzles
Yu-Sheng Liu, David McKeen, Gerald A. Miller
A new scalar boson which couples to the muon and proton can simultaneously solve the proton radius puzzle and the muon anomalous magnetic moment discrepancy. Using a variety of mea…
