Z/γ∗ plus multiple hard jets in high energy collisions (2016)
Journal Article
Andersen, J. R., Medley, J. J., & Smillie, J. M. (2016). Z/γ∗ plus multiple hard jets in high energy collisions. Journal of High Energy Physics, 2016(05), Article 136. https://doi.org/10.1007/jhep05%282016%29136

We present a description of the production of di-lepton pair production (through Z boson and virtual photon) in association with at least two jets. This calculation adds to the fixed-order accuracy the dominant logarithms in the limit of large parton... Read More about Z/γ∗ plus multiple hard jets in high energy collisions.

Systematics of quark/gluon tagging (2017)
Journal Article

By measuring the substructure of a jet, one can assign it a “quark” or “gluon” tag. In the eikonal (double-logarithmic) limit, quark/gluon discrimination is determined solely by the color factor of the initiating parton (CF versus CA). In this paper,...
