Grant: Subatomic Physics Envelope - Individual
Carleton University
$80,000.00
Completion of the heavy flavour physics program at CLEO
FY 2008-09
Summary
Cornell's Laboratory for Elementary Particle Physics hosts the CLEO-c experiment, which over the last five years, has collected data near the charm production threshold. The CLEO collaboration consists of 22 collaborating institutions among which Carleton University has been enumerated since 1993. Professor Asner now leads the Carleton group on CLEO and is currently one of the two elected Spokesmen of the collaboration.
The full data sample, now almost completely in hand, will consist of over 10 million D mesons - a particle containing a charm quark and an anti-up or anti-down quark, approximately 1.2 million Ds mesons - a particle containing a charm quark and an anti-strange quark - and 27 million psi mesons - which contain a charm quark and an anti-charm quark. These unprecedented "charm" data samples were collected in the superb CLEO-c detector, which provides excellent electromagnetic calorimetry, charged particle tracking and identification, and near 4pi solid angular coverage.
The intellectual merit of the CLEO-c physics program stems from its impact on heavy flavour physics which includes the study of charm and the theory of the strong force QCD - quantum chromodynamic. Also, the CLEO program will enable numerous other measurements that will deepen our understanding of D and Ds meson phenomenology.
Professor Asner's team is spearheading the studies of strong and weak phases in charm transitions. These results contribute to our understanding of matter-anti-matter oscillations and asymmetry.
These results will substantially extend the reach and understanding of heavy flavour physics, allowing the Canadian particle physics community to reap the benefits of their investment in the CLEO-c, BaBar, CDF and D0 experiments which are hosted by laboratories in the USA. The world community will benefit as results from CLEO-c will extend the reach of the Belle experiment at KEK (Japan) and LHCb experiment at CERN (France) and lay the foundation for the physics program of the BESIII experiment in China.
