T0 Time Resolution

•The lack of prompt T0s for collision events has a number of consequences:

•

•The T0 vertex resolution does not improve when the multiplicity of the event increases.

•

•The collision time resolution does not improve when the multiplicity of the event increases.

•

•The only approach we can take in selecting the prompt T0 counter is to take the first T0 counter that fires in a particular event.
