CLEO-c at CESR

In October 2005, Indiana Univeristy joined the CLEO-c Collaboration at Cornell University's Laboratory for Elementary Particle Physics. Matt Shepherd has been a CLEO-c collaborator since 2001, when he joined the collaboration as a Cornell University graduate student.

In the coming year the 30M ψ^′ decays will be collected with the CLEO-c detector. Matt Shepherd and Ryan Mitchell are developing a program to do systematic amplitude analysis of hadronic χ_c decays from this data set. Hadronic χ_c decay provides a glue-rich environment ideal for probing the glueball spectrum. Studies of χ_c decay are also complementary to high statistics J/ψ results coming from the BES collaboration.

In addition to amplitude analysis, Ryan Mitchell is also part of a group responsible for maintaining the CLEO-c trigger hardware.
