Symbiosis and long-term physics interests & collaboration with LBNL & Wayne State physicists

Cost, Scope, Size of Re-direction of Effort

Manpower and resource re-direction from STAR to ALICE

Yale effort on ALICE: 36% in 2007  66% in 2009

One-time institutional fee and annual Maintenance and Operation (M&O) fees for Yale Ph.D. authors to participate in ALICE

$36K one-time institutional fee for Yale in ALICE
