Detailed Description

Simple two track PID for gamma and Ks.

This algorithm calulates the mass of all combinations of Track pairs with opposite charges. If the tracks mass is consistent with the processes gamma ->ee or Ks -> pi+pi- the tracks are flagged and a pointer is inserted into the map under the correct key (either gamma or Ks) The parameters of this algorithm are:

Parameters

MaxGammaMass	upper limit on the photon mass
MinKsMass	lower limit on the Ks mass
MaxKsMass	upper limit on the Ks mass
Chi2Cut	cut on the Chi squared for the two tracks beinig in the same vertex.
RPhiCut	cut on the maximum RPhi of the vertex that the tracks form.
SignificanceCut	cut on the minimum rphi significance of the tracks with respect to the IP.

Member Function Documentation

std::map< PidCutType, std::vector< Track * > > vertex_lcfi::TwoTrackPid::calculateFor ( Jet * MyJet ) const

virtual

Run the algorithm on a Jet.

Calculates whether two tracks are consistent with the hypothesis of gamma-> ee or with the hypothesis gamma->pi pi . In case the tracks are consisten with either of these hypothesis the algorithm puts a pointer to these tracks into the correct key of the resulting map.

Parameters

Jet	Pointer to Jet to be analysed

Returns: map containing two keys Gamma and Ks which hold the tracks that satisfy these criteria.
