Uncertainties of predictions from parton distributions II: theoretical errors (2004)
Journal Article
Martin, A., Roberts, R., Stirling, W., & Thorne, R. (2004). Uncertainties of predictions from parton distributions II: theoretical errors. The European Physical Journal C, 35(3), 325-348. https://doi.org/10.1140/epjc/s2004-01825-2

We study the uncertainties in parton distributions, determined in global fits to deep inelastic and related hard scattering data, due to so-called theoretical errors. Amongst these, we include potential errors due to the change of perturbative order... Read More about Uncertainties of predictions from parton distributions II: theoretical errors.

Double-diffractive χ meson production at the hadron colliders (2004)
Journal Article
Khoze, V., Martin, A., Ryskin, M., & Stirling, W. (2004). Double-diffractive χ meson production at the hadron colliders. The European Physical Journal C, 35(2), 211-220. https://doi.org/10.1140/epjc/s2004-01857-6

The double-diffractive production of χcχc and χbχb mesons, with a rapidity gap on either side, is studied, using both the Regge formalism and the perturbative QCD approach. Due to the rather low scale, the exclusive double-diffractive process pp→p+χ+... Read More about Double-diffractive χ meson production at the hadron colliders.
