Modeling pion physics in the {epsilon}-regime of two-flavor QCD using strong coupling lattice QED

Journal Article Cecile, D J ; Chandrasekharan, Shailesh - Physical Review. D, Particles Fields

In order to model pions of two-flavor QCD we consider a lattice field theory involving two flavors of staggered quarks interacting strongly with U(1) gauge fields. For massless quarks, this theory has an SU{sub L}(2)xSU{sub R}(2)xU{sub A}(1) symmetry. By adding a four-fermion term we can break the U{sub A}(1) symmetry and thus incorporate the physics of the QCD anomaly. We can also tune the pion decay constant F, to be small compared to the lattice cutoff by starting with an extra fictitious dimension, thus allowing us to model low energy pion physics in a setting similar to lattice QCD frommore »« less

Nucleon momentum fraction, helicity and transversity from 2+1-flavor lattice QCD

Journal Article Mondal, Santanu ; Gupta, Rajan ; Park, Sungwoo ; ... - Journal of High Energy Physics (Online)

Abstract A detailed analysis of the systematic uncertainties in the calculation of the isovector momentum fraction, 〈x〉u − d, helicity moment, 〈x〉Δu − Δd, and the transversity moment, 〈x〉δu − δd, of the nucleon is presented using high-statistics data on seven ensembles of gauge configurations generated by the JLab/W&M/LANL/MIT collaborations using 2 + 1-flavors of dynamical Wilson-clover quarks. The much higher statistics have facilitated better control over all systematics compared to previous lattice calculations. The least understood systematic — excited-state contamination — is quantified by studying the variation of the results as a function of different estimates of the mass gap of the first excited state, obtained from two- and three-point correlation functions, and as a function of the pion mass Mπ. The final results are obtained using a simultaneous fit in the lattice spacing a, pion mass Mπ and the finite volume parameter MπL keeping leading order corrections. The data show no significant dependence on the lattice spacing and some evidence for finite-volume corrections. Our final results, in themore »« less
