Revisiting strong-coupling determinations from $e^{+} e^{-}$ event shapes

Guido Bell, Christopher Lee, Yiannis Makris +2

We reassess the theoretical uncertainties of strong-coupling determinations from a global fit to the $e^{+} e^{-}$ thrust data, focusing in particular on the scheme dependence associat…

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 $e^{+} e^{-}$ colliders. Angularities $I ¨ _{a}$ are a class of 2-jet event shap…
