Detailed Description

A plugin for FastJet (v3.0 or later) that provides an interface to the D0 version of Run-I cone algorithm.

The D0 code has been obtained from Lars Sonnenschein's web-space http://www-d0.fnal.gov/~sonne/D0RunIcone.tgz

The version of the D0 Run I code distributed here has been modified by the FastJet authors, so as to provide access to the contents of the jets (as is necessary for the plugin). This does not modify the results of the clustering.

The difference between this algorithm and the post-1996 version relates to the way the final jet momenta are calculated. Details are to be found in FERMILAB-PUB-97-242-E.

Constructor & Destructor Documentation

fastjet::D0RunIConePlugin::D0RunIConePlugin	(	double	CONErad_in,
		double	JETmne_in,
		double	SPLifr_in = _DEFAULT_SPLifr
	)		[inline]

The D0RunIConePlugin constructor, which sets the "free" parameters of the algorithm:

Parameters:

CONErad	is the cone radius
JETmne	is a minimum ET requirement on every iteration (jet dropped if Et < JETmne * Et_min_ratio ). The value that has been used by D0 for JETmne: 8 GeV (and Et_min_ratio is 0.5)
SPlifr	is the shared Et fraction splitting threshold, and a value of 0.5 was usually used by D0

The remaining parameters of the algorithm are not to be modified if the algorithm is to correspond to the one actually used by D0.
