property alpha_qcd¶: QCD coupling at the event scale.

property alpha_qed¶: QED coupling at the event scale.

format(self: madspace._madspace_py.LHEEvent) → str¶: Append this event’s LHE text to buffer.

property particles¶: One entry per particle, incoming and outgoing.

property process_id¶: Process id, matching one of LHEMeta::processes.

property rwgt¶

property rwgt_ids¶: Optional LHEF v3 weights (<rwgt> block); rwgt_ids and rwgt have the same length.
