Description
Parton showers are important tools in the event generation chain for the LHC experiments. Recently, their formally achieved accuracy has been under extended scrutiny. In this talk I will present a novel take on coherent parton evolution, resulting in the design of a new parton shower called Alaric that is implemented in the Sherpa framework. I will discuss its resummation properties and show analytic and numerical proofs of its NLL accuracy. I will also present a first comparison to LEP data as a standard validation exercise.
