Pion distribution amplitude from Euclidean correlation functions
Gunnar S. Bali, Vladimir M. Braun, Benjamin Gläßle +8
Following the proposal in [1], we study the feasibility to calculate the pion distribution amplitude (DA) from suitably chosen Euclidean correlation functions at large momentum. In…
Second moment of the pion distribution amplitude with the momentum smearing technique
RQCD Collaboration, G. S. Bali, V. M. Braun +6
Using the second moment of the pion distribution amplitude as an example, we investigate whether lattice calculations of matrix elements of local operators involving covariant deri…
Novel quark smearing for hadrons with high momenta in lattice QCD
Gunnar S. Bali, Bernhard Lang, Bernhard U. Musch +1
Hadrons in lattice QCD are usually created employing smeared interpolators. We introduce a new quark smearing that allows us to maintain small statistical errors and good overlaps…
