Probing the CP violation effects via the angular coefficients in Drell-Yan production
Qingyi Situ, Bin Yan
The naive--odd angular coefficients -- in Drell--Yan production are highly suppressed in the Standard Model (SM), making them sensitive probes of CP-violating interact…
Revisiting strong-coupling determinations from event shapes
Guido Bell, Christopher Lee, Yiannis Makris +2
We reassess the theoretical uncertainties of strong-coupling determinations from a global fit to the thrust data, focusing in particular on the scheme dependence associat…
Effects of Renormalon Scheme and Perturbative Scale Choices on Determinations of the Strong Coupling from Event Shapes
Guido Bell, Christopher Lee, Yiannis Makris +2
We study the role of renormalon cancellation schemes and perturbative scale choices in extractions of the strong coupling constant and the leading non-perturbative shift…
Probing light quark Yukawa couplings through angularity distributions in Higgs boson decay
Bin Yan, Christopher Lee
We propose to utilize angularity distributions in Higgs boson decay to probe light quark Yukawa couplings at colliders. Angularities are a class of 2-jet event shape…
