Detailed Description

Macro MUONmassPlot_ESD.C for ESD.

Author

Ch. Finck, Subatech, April. 2004

Macro to make invariant mass plots for combinations of 2 muons with opposite charges, from root file "MUON.tracks.root" containing the result of track reconstruction. Histograms are stored on the "MUONmassPlot.root" file. introducing TLorentzVector for parameter calculations (Pt, P,rap,etc...) using Invariant Mass for rapidity.

Add parameters and histograms for analysis

Function Documentation

Bool_t MUONmassPlot	(	const char *	esdFileName = "AliESDs.root",
		const char *	geoFilename = "geometry.root",
		const char *	ocdbPath = "local://$ALICE_ROOT/OCDB",
		Int_t	FirstEvent = 0,
		Int_t	LastEvent = -1,
		Int_t	ExtrapToVertex = -1,
		Int_t	ResType = 553,
		Float_t	Chi2Cut = 100.,
		Float_t	PtCutMin = 1.,
		Float_t	PtCutMax = 10000.,
		Float_t	massMin = 9.17,
		Float_t	massMax = 9.77
	)

Parameters

FirstEvent	(default 0)
LastEvent	(default 10000)
ExtrapToVertex	(default -1) <0: no extrapolation; =0: extrapolation to (0,0,0); >0: extrapolation to ESDVertex if available, else to (0,0,0)
ResType	553 for Upsilon, anything else for J/Psi (default 553)
Chi2Cut	to keep only tracks with chi2 per d.o.f. < Chi2Cut (default 100)
PtCutMin	to keep only tracks with transverse momentum > PtCutMin (default 1)
PtCutMax	to keep only tracks with transverse momentum < PtCutMax (default 10000)
massMin	(default 9.17 for Upsilon)
massMax	(default 9.77 for Upsilon); to calculate the reconstruction efficiency for resonances with invariant mass massMin < mass < massMax.
