First constraints on the nonperturbative gluon Collins-Soper kernel
Artur Avkhadiev, Yang Fu, Phiala E. Shanahan +2
The gluon Collins-Soper kernel, which encodes the rapidity evolution of transverse-momentum-dependent gluon distributions, is constrained for the first time in the nonperturbative…
Learning the generating functional for variance reduction in lattice QCD
Ryan Abbott, Yang Fu, Daniel C. Hackett +3
The generating functional in quantum field theory provides the natural framework for constructing correlation functions as derivatives with respect to source operators. We present…
Variance reduction in lattice QCD observables via normalizing flows
Ryan Abbott, Denis Boyda, Yang Fu +5
Normalizing flows can be used to construct unbiased, reduced-variance estimators for lattice field theory observables that are defined by a derivative with respect to action parame…
An extraction of the Collins-Soper kernel from a joint analysis of experimental and lattice data
Artur Avkhadiev, Valerio Bertone, Chiara Bissolotti +6
We present a first joint extraction of the Collins-Soper kernel (CSK) combining experimental and lattice QCD data in the context of an analysis of transverse-momentum-dependent dis…
Lattice QCD calculation of the subtraction function in forward Compton amplitude
Yang Fu, Xu Feng, Lu-Chang Jin +2
The subtraction function plays a pivotal role in calculations involving the forward Compton amplitude, which is crucial for predicting the Lamb shift in muonic atom, as well as the…
Lattice QCD calculation of the pion charge radius using a model-independent method
Xu Feng, Yang Fu, Lu-Chang Jin
We use a method to calculate the hadron's charge radius without model-dependent momentum extrapolations. The method does not require the additional quark propagator inversions on t…
