QCD Chiral Crossover Line from Lee-Yang Edge Singularities
Heng-Tong Ding, Swagato Mukherjee, Peter Petreczky +1
We propose a universality-based reconstruction of the QCD chiral crossover line from Lee-Yang edge singularities in the complex baryon chemical potential plane. The framework maps…
Proton isovector helicity PDF at NNLO and the twist-3 moment from lattice QCD at physical quark masses
Xiang Gao, Andrew D. Hanlon, Swagato Mukherjee +5
We present a lattice quantum chromodynamics calculation of the -dependent isovector quark helicity parton distribution function (PDF) of the proton in the large momentum effecti…
Quark-Mass Dependence of Light-Nuclei Masses from Lattice QCD and Trace-Anomaly Contributions to Nuclear Bindings
Debsubhra Chakraborty, Noah Chavez, Xiang Gao +2
We present lattice QCD calculations of the masses of the deuteron, dineutron, Helium-3 and Helium-4 with physical sea quarks and valence quark masses corresponding to pion masses b…
Nucleon Parton Distribution Functions from Boosted Correlations in the Coulomb gauge
Xiang Gao, Jinchen He, Joshua Lin +4
Recently, a novel approach has been proposed to compute parton distributions through the use of boosted correlators fixed in the Coulomb gauge from lattice QCD, within the framewor…
Lattice-QCD validation of hadron mass and trace-anomaly decomposition sum rules
Dennis Bollweg, Heng-Tong Ding, Xiang Gao +2
We present the first lattice-QCD validation of multiple sum rules associated with quark-gluon decomposition of hadron mass by computing all components from first principles. We ach…
QCD Crossover at Low Temperatures from Lee-Yang Edge Singularity
D. A. Clarke, H. -T. Ding, J. -B. Gu +6
We provide the first lattice-QCD estimate of the crossover line down to ~MeV. We introduce a new method that combines the Lee-Yang edge in the complex plane of baryon c…
