The role of zero-mode contributions in the matching for the twist-3 PDFs and
Shohini Bhattacharya, Krzysztof Cichy, Martha Constantinou +3
The perturbative procedure of matching was proposed to connect parton quasi-distributions that are calculable in lattice QCD to the corresponding light-cone distributions which ent…
One-loop matching for the twist-3 parton distribution
Shohini Bhattacharya, Krzysztof Cichy, Martha Constantinou +3
Perturbative matching relates the parton quasi-distributions, defined by Euclidean correlators at finite hadron momenta, to the light-cone distributions which are accessible in exp…
Flavor symmetry breaking in the sea
J. J. Ethier, W. Melnitchouk, Fernanda Steffens +1
The discovery of a sizeable asymmetry in the and distributions in the proton was one of the more consequential experimental findings in hadron physics last centur…
Decoupling heavy particles simultaneously
R. J. Crewther, S. D. Bass, F. M. Steffens +1
The renormalization group is extended to cases where several heavy particles are decoupled at the same time. This involves large logarithms which are scale-invariant and so cannot…
Matching functions for heavy particles
S. D. Bass, R. J. Crewther, F. M. Steffens +1
We introduce matching functions as a means of summing heavy-quark logarithms to any order. Our analysis is based on Witten's approach, where heavy quarks are decoupled one at a tim…
Heavy-quark axial charges to non-leading order
S. D. Bass, R. J. Crewther, F. M. Steffens +1
We combine Witten's renormalization group with the matching conditions of Bernreuther and Wetzel to calculate at next-to-leading order the complete heavy-quark contribution to the…
Mesonic Corrections to the Shape of Quark Distributions
F. M. Steffens, H. Holtmann, A. W. Thomas
We compute the full x - dependence of the proton and neutron spin structure functions in the MIT bag model, including the effect of gluon exchange and the meson cloud. Impressive a…
