Resonance meeting



Minute meeting 11-03-2011


 1) Update on D(1232)++/--  analysis in p-p , to be improved statistics for different PID cuts selection.

2) Event mixing update.  Event mixing is now capable to apply correctly the physics selections also to
the  mixed event, and then it is fully operational for p-p and Pb-Pb events. Classes to allow mixing to
properly work with Tender are ready but they wait for the approval for being committed in SVN

3)  Show first results on f(1020) in Pb-Pb.  Martin doing a local analysis on SKAF was able to extract a
phi  peak (global multiplicity and pt).  Alberto working on Alien analyzed only a small set of events (600 )
then this is only  a check of the estimate of the background by event mixing.

4) Problem to run with Pb-Pb data.  Problem of  EXPIRED or ERROR EXCUTION, these are due to
the fact that the jobs are too long.  Alberto and Martin are working on this.  Probably solution will be
ready for the beginning of next week.

5) Alberto reported about the news from Spectra group. i.e. 1) Found a ‘correct’ estimator of the
 multiplicity (clusters in SPD) for p-p events, 2) now it is possible to use new the QA cuts for TPC 
suggested by Marian. This can be found  in AliESDtrackCuts::GetStandardITSTPCTrackCuts2010(kTRUE,1);   (see slides for more information).
