abstract
We study the logarithmic accuracy of angular-ordered parton showers by considering the singular limits of multiple emission matrix elements. This allows us to consider different choices for the evolution variable and propose a new choice which has both the correct logarithmic behaviour and improved performance away from the singular regions. In particular the description of $e^+e^-$ event shapes in the non-logarithmic region is significantly improved.

Timelike showers with jet recoils
A 'jet recoil' scheme assigning momentum-balance recoil to clusters of partons chosen by angular ordering brings kt-ordered dipole parton showers to next-to-leading-logarithmic accuracy, shown by fixed-order and resum...

Soft-gluon coupling and the TMD parton branching Sudakov form factor
The parton branching TMD framework is upgraded from NLL to NNLL accuracy using the soft-gluon physical coupling, with the Collins-Soper kernel evaluated at NNLL.

High dimensional parameter tuning for event generators
Autotunes splits event generator parameter spaces into correlated subspaces and assigns automatic observable weights, enabling iterative Professor-based tuning in higher dimensions than the standard approach.

How much joint resummation do we need?
Joint resummation of two angularities, rather than one or many, yields the largest gain in predicting other angularities in e+ e- dijet events.
