Large-momentum effective theory

Abstract: Since the parton model was introduced by Feynman more than fifty years ago, we have learned much about the partonic structure of the proton through a large body of high-energy experimental data and dedicated global fits. However, calculating the partonic observables such as parton distribution function (PDFs) from the fundamental theory of strong interactions, QCD, has made limited progress. Recently, the authors have advocated a formalism, large-momentum effective theory (LaMET), through which one can extract… Show more

“…The pion was also suggested to be massless due to other reasons [9]. Recently these arguments were revisited [10], and "quasi-PDF" have been calculated on the lattice [11] (and references therein), obviously with all nonperturbative effects included.…”

“…Several proposals to implement this idea exist [2][3][4][5][6][7]. The particular choice of the correlation function of the quark and antiquark fields connected by the Wilson line [5] received the most attention, see, e.g., [8,9] for a review. In order to distinguish these objects from their light-cone analogs, one usually refers to such space-like correlation functions as pseudo-PDFs (e.g.…”

“…There have been a lot of lattice studies on the pion/kaon DA using the traditional moments approach [18][19][20][21][22][23][24]. The recently proposed large-momentum effective theory (LaMET) [25][26][27] allows to access the entire x-dependence of the DAs from first principle lattice calculations, instead of only the first few moments (for other proposals with applications to the DAs, see Refs. [28][29][30][31]).…”
