pylhe.LHEProcInfo

class pylhe.LHEProcInfo(xSection: float, error: float, unitWeight: float, procId: int, npLO: int | None = None, npNLO: int | None = None)[source]

Bases: object

Store the process info block as a dataclass.

__init__(xSection: float, error: float, unitWeight: float, procId: int, npLO: int | None = None, npNLO: int | None = None) → None

Methods

`__init__`(xSection, error, unitWeight, procId)
`fromstring`(string)	Create an LHEProcInfo instance from a string in LHE format.
`tolhe`(lheformat)	Return the process info block as a string in LHE XML format.

Attributes

`npLO`	LO final-state multiplicity tag for HDF5 procInfo tables
`npNLO`	Born-level multiplicity tag for HDF5 procInfo tables
`xSection`	Cross section of the process
`error`	Uncertainty/error of the cross section
`unitWeight`	Unit weight of the process
`procId`	Process ID

error: float: Uncertainty/error of the cross section

classmethod fromstring(string: str) → LHEProcInfo[source]: Create an LHEProcInfo instance from a string in LHE format.

npLO: int | None = None: LO final-state multiplicity tag for HDF5 procInfo tables

npNLO: int | None = None: Born-level multiplicity tag for HDF5 procInfo tables

procId: int: Process ID

Return the process info block as a string in LHE XML format.

Returns:: str: The process info block as a string in LHE XML format.

unitWeight: float: Unit weight of the process

xSection: float: Cross section of the process
