C-parameter Distribution at N${}^3$LL${}^{\prime }$ including Power Corrections

André H. Hoang, Daniel W. Kolodrubetz, Vicent Mateu +1

We compute the $e^{+}{e}^{-}$ C-parameter distribution using the Soft-Collinear Effective Theory with a resummation to N${}^3$LL${}^{\prime }$ accuracy of the most singular partonic terms. T…
