Meaning
of the variables in the DAFNE scan lists:
In the scan lists
writen out by DAFNE, in addition to the tagging results for each event,
a set of physical quantities helpful in characterizing the event
is provided. The meaning of each variable is explained here:
| Ecm | Centre-of-mass energy |
| Ncha | Charged multiplicity (good tracks only) |
| Evis | Total visible energy |
| Ptmis | transverse missing momentum |
| Mvis | Total visible mass |
| LID | Lepton identification code:
XYZ
(X=nb. of isolated elecrons, Z=nb. of isolated muons, Y=nb. of isolated non-identified charged) |
| Pisol | Momentum of the most energetic isolated lepton
(remark: in the beginning of 99A it is the isolation angle...) |
| Btag | event Btag probability (for events tagged by the hA or hnunu routines) (-5=not computed) |
| Eami | Lowest energy x lowest angle (4 jet events!) |
| Mass fit m1=m2 | mass from the constraint fit imposing equal masses (4 jet events!) |
| Mass fit mz | jet pair mass imposing the Z mass on the other pair (4 jet events!) |
