Trivializing Flow in 2D O(3) sigma model
Christopher Chamness, Kostas Orginos, Daniel Kovner
The two dimensional O(3) sigma model, just as quantum chromodynamics, is an asymptotically free theory with a mass gap. Therefore, it is an interesting and simple toy model to inve…

Extracting the Pion Distribution Amplitude from Lattice QCD through Pseudo-Distributions
Daniel Kovner, Joe Karpie, Konstantinos Orginos +2
The Light-Cone Distribution Amplitude (LCDA) encodes the non-perturbative information of the leading Fock component of the hadron wave function, therefore required for processes in…
