A standard file format is proposed to store process and event information, primarily output from parton-level event generators for further use by general-purpose ones. The information content is identical with what was already defined by the Les Houches Accord five years ago, but then in terms of Fortran commonblocks. This information is embedded in a minimal XML-style structure, for clarity and to simplify parsing.

Tuning PYTHIA 8.1: the Monash 2013 tune (2014, methodology): “Especially in the latter context of matrix-element matching, we expect that in many cases PYTHIA 8 will be used together with codes such as ALPGEN [127], MADGRAPH [128], aMCatNLO [129], or POWHEG [130], either using the matching algorithms of those programs themselves, or via any of PYTHIA’s several”

Searching for long-lived particles beyond the Standard Model at the Large Hadron Collider (2019, methodology): “Depending on how the LLP program expands and develops over the next few years, it may become expedient to expand the simplified model library to include sets of events in a standard format (such as the Les Houches format [217]) that can be directly fed into event-generator and detector-simulation pr”
