Atlantis an event display for ATLAS: When displaying 6000 hits recorded by only
7 layers, can we recognize tracks?
- Santa Cruz
An ATLAS event may contain hits from the triggering event - probably of very
high multiplicity - and from other events which occur almost simultaneously.
For such cases, the "V-plot" significantly helps to recognise tracks or
track clusters. The tracks within these clusters may be distinguished
by simple magnifications. A specialised 3-dimensional cleaning procedure
further improves track recognition, especially when applied in conjunction
with the V-plot.
We will demonstrate the use of the V-plot and the use of fast algorithms a) to
find primary vertices and b) to eliminate hits not belonging to the
