High precision tests of QCD without scale or scheme ambiguities
Leonardo Di Giustino, Stanley J. Brodsky, Philip G. Ratcliffe +2
A key issue in making precise predictions in QCD is the uncertainty in setting the renormalization scale and thus determining the correct values of the QCD running coupling $…
On the Evolution of Sum Rules for T-Odd Distribution and Fragmentation Functions
Philip G. Ratcliffe, Oleg V. Teryaev
We test stability against probabilistic evolution of sum rules for transverse-momentum-dependent distribution and fragmentation functions. We find that preservation of the Burkardt…
Single Transverse-Spin Asymmetries in Drell-Yan Processes
Gabriele Re Calegari, Philip G. Ratcliffe
The asymmetry in the angular distribution of Drell--Yan dilepton pairs generated in collisions where just one nucleon is transversely polarised has been examined in the literature…
Colour Modification of Factorisation in Single-Spin Asymmetries
Philip G. Ratcliffe, Oleg Teryaev
We discuss the way in which factorisation is partially maintained but nevertheless modified by process-dependent colour factors in hadronic single-spin asymmetries. We also examine…
Non-Universality and Evolution of the Sivers Function
Philip G. Ratcliffe, Oleg Teryaev
We examine the large-x QCD evolution of the twist-three gluonic-pole strength defining an effective T-odd Sivers function, where evolution of the T-even transverse-spin DIS structu…
Dominant Contribution in Pion Production Single-Spin Asymmetries
Philip G. Ratcliffe, Marco Ramilli
Working with a completely collinear twist-3 factorized cross-section formula, we identify two largely dominant partonic sub-processes, which contribute to the single-spin asymmetri…
