Query: Multi-Emission Kernels for Parton Branching Algorithms   We introduce a general framework to construct multi-emission kernels for
parton branching algorithms at the amplitude level and across different soft
and collinear limits. We highlight the connection of kinematic
parameterizations and recoil schemes to the underlying power counting, and
discuss in detail how soft radiation can be partitioned in between different
collinear configurations beyond the single-emission picture underpinning the
traditional dipole and angular ordering approaches. Our work is a vital
cornerstone to build parton branching algorithms which include
multiply-unresolved emissions in a fully differential way, and our construction
can also be used to obtain splitting functions for probabilistic algorithms or
other cross-section level objects such as subtraction terms.
