STAR HardProbes PWG

["Mooney, Isaac" <isaac.mooney AT yale.edu>]

Hi all,

As I mentioned in the PWG meeting on the 8th, we’ve been asked to give input on the prescales for HardProbes-related triggers for the upcoming high-luminosity data-taking period. Specifically, due to high rates from the dimuon and BHT1 triggers, these may require a high prescale to limit their bandwidth. Our request is for analyzers planning to use Run 23 data with these triggers to provide a desired overall number of events for each trigger in order to meet the physics goals for the analysis. If we assume a given number of weeks of running, this then gives a rough estimate of the prescale we should apply.

I’m also linking my slides from last week (https://drupal.star.bnl.gov/STAR/system/files/TriggerRates100k_Run23.pdf) with a few changes, including a rate table on the last slide estimated by Akio, along with some back-of-the-envelope calculations I added for the prescale of these two triggers.

Please let us know if you have any questions or input.

Thanks,

Isaac, Nihar, and Yi
