Minutes of the Rare Particle Meeting,
Bologna 12.06.2000
Present:
Fausto Guarino, Ivan De Mitri, Mario Sitta, Fabrizio Cei, Miriam Giorgini,
Vlad Popa, Mohamed Ouchrif, Laura Patrizii, Shahid Manzoor, Giorgio Giacomelli,

1) Status of MM analyses
-STREAMER: Fausto will update (beginning of July) the analysis using data
since January 1,2000 after checking for possible Y2k bugs.
-WFD: Erik forwarded to Laura the US DOE report. It appears that the analysis
is not yet finalised. As already agreed at the last coll. meeting at GS,
a complete and detailed MACRO Memo is needed in order to better understand
and use this analysis.
-PHRASE: updated until 31.1.99; Mohamed will cover the gap (August 94 - June 95)
of the Attico part. After Mohamed will leave the group (next fall), Fabrizio
will continue the analysis till the end of data taking.
-TRACK-ETCH: Starting May 1st Shahid begun the mass etching at GS. By now we
etched and scanned a total of 345 m2 of CR39. We expect a total analysed area
of about 500 m2 by the end of the year. We reached (preliminary result) the Ohya
limit (in the beta-range in which the MACRO limit was not the lowest yet).
-FAST COMBINED: Ivan's new update will be available by July 9.
-CATALYSIS: Mario's simulation results are presented in the MACRO-Memo 4/00.
By the beginning of July some real data analysis will be made.
2) Other exotica
-LIPs: As for slow MMs, a detailed report (Memo) including "final numbers"
is needed in order to understand and quote the analysis results (not
available yet).
-Q-balls: Some recent papers are referring to MACRO as potentially sensitive
to charged Q-balls (i.e. hep-ph/0005103). Mohamed will define the ranges of the
parameters (mass, baryonic charge, velocity) for charged Q-balls for which the
MM analysis results are applicable to Q-balls. For neutral Q-balls
Mohamed & Mario will try to simulate their interactions in the apparatus.
-Nuclearites: A new update was presented.
3) Conferences, papers
The group decided to prepare a note (>= 6 pages) to be used as
reference for the summer conferences. The draft will be made available by
July 9 by Laura & Vlad, and discussed at the next meeting of July, at GS.
THE NEXT MEETING IS PLANNED FOR JULY 12 or 13 AT GS. IT WOULD BE
VERY IMPORTANT TO HAVE AN AMERICAN REPRESENTATIVE.
