# A Simple shower and matching algorithm

@article{Giele2007ASS, title={A Simple shower and matching algorithm}, author={Walter T. Giele and David A. Kosower and Peter Skands}, journal={Physical Review D}, year={2007}, volume={78}, pages={014026} }

We present a simple formalism for parton-shower Markov chains. As a first step towards more complete ''uncertainty bands,'' we incorporate a comprehensive exploration of the ambiguities inherent in such calculations. To reduce this uncertainty, we then introduce a matching formalism which allows a generated event sample to simultaneously reproduce any infrared-safe distribution calculated at leading or next-to-leading order in perturbation theory, up to subleading corrections. To enable a more…
