Visualization of semileptonic form factors from lattice QCD
Physical Review D
Comparisons of lattice-QCD calculations of semileptonic form factors with experimental measurements often display two sets of points, one each for lattice QCD and experiment. Here we propose to display the output of a lattice-QCD analysis as a curve and error band. This is justified, because lattice-QCD results rely in part on fitting, both for the chiral extrapolation and to extend lattice-QCD data over the full physically allowed kinematic domain. To display an error band, correlations in thedoi:10.1103/physrevd.80.034026 fatcat:2767sbro3ff2rietxghkncy6h4
