Detailed Description

This class converts the Events into HepMC::GenEvents.

The output is depended on the HepMC version HEJ is compiled with, both HepMC 2 and HepMC 3 are supported. If HEJ 2 is compiled without HepMC calling this interface will throw an error.

This interface will also keep track of the cross section of all the events that being fed into it.

Member Function Documentation

init_event()

HepMC::GenEvent HEJ::HepMC2Interface::init_event ( Event const &  event ) const

protected

initialise generic event infomrations (not central weights)

Parameters

event

Event to convert

operator()()

HepMC::GenEvent HEJ::HepMC2Interface::operator()	(	Event const &	event,
		int	weight_index = -1
	)

main function to convert an event into HepMC::GenEvent

Parameters

event	Event to convert
weight_index	optional selection of specific weight (negative value gives central weight)

set_central()

void HEJ::HepMC2Interface::set_central	(	HepMC::GenEvent &	out_ev,
		Event const &	event,
		int	weight_index = -1
	)

Sets the central value from event to out_ev.

Parameters

out_ev	HepMC::GenEvent to write to
event	Event to convert
weight_index	optional selection of specific weight (negative value gives "central")

This overwrites the central value of out_ev.

set_xs_scale()

void HEJ::HepMC2Interface::set_xs_scale

(

double

scale

)

Set the ratio (cross section) / (sum of event weights)
