pylhe.LHEEventInfo

class pylhe.LHEEventInfo(nparticles: int, pid: int, weight: float, scale: float, aqed: float, aqcd: float)

Bases: object

Store the event information in the LHE format.

__init__(nparticles: int, pid: int, weight: float, scale: float, aqed: float, aqcd: float) → None

Methods

__init__(nparticles, pid, weight, scale, ...)
fromstring(string)	Create an LHEEventInfo instance from a string in LHE format.
tolhe()	Return the event info as a string in LHE format.

Attributes
