Hello, Mary.

Here's my information for the November 19 seminar at LBL. Please let
me know if you need any other information. I have my plane ticket
(price to be shared with SLAC) and I will NOT need a hotel room.
I also know the directions to LBL, so I will just arrive on November 19
at the LBL main entrance, anticipating a visitor parking permit for
the 19th and 20th.

Best regards, Greg Snow

Title of talk                : Search for antiproton decay and the stability
                               of antimatter
Abstract                     :
*********************************
The APEX collaboration has searched for antiproton decay in a number
of channels using the circulating 8.9 GeV/c antiprotons in the
Fermilab antiproton accumulator ring. The experiment is sensitive to
antiproton decays with an electron or muon in the final state which is
accompanied by another particle (photon, neutral pion, etc.).
Observing antiproton decay with a lifetime different from the proton
lifetime (> 10**32 years) would signal a violation of the CPT theorem.
A review of proton decay searches and experimental CPT tests will be
presented. A description of the APEX experiment and recent results
will follow. The results point to a lower limit on the antiproton
lifetime of order 1,000,000 years -- an improvement over previous
searches of several orders of magnitude.

At the end of the seminar, a unique high-school physics outreach project,
Nebraska's "CROP" (the Cosmic Ray Observatory Project), will
be described briefly.
