Dear sPHENIX and STAR experimenters,

 

attached please find an update of the RHIC projections.

The latest version of this document is always posted here: https://www.rhichome.bnl.gov/RHIC/Runs/RhicProjections.pdf

 

For p+p, the delivered luminosity for different crossing angles and vertex regions is stated Table 2.

To deliver ~75 pb^-1 to sPHENIX in +-10 cm will take approximately 20 weeks without any improvements over Run-15.

 

Please distribute as needed, and let me know if you need any further information.

Subject: New RHIC projections for Run-24 and Run-25

 

Dear sPHENIX and STAR experimenters,

 

attached please find an update of the RHIC projections.

The latest version of this document is always posted here: https://www.rhichome.bnl.gov/RHIC/Runs/RhicProjections.pdf

 

For p+p, in light of this year’s run experience (even without all the AC problems), we cannot count on exceeding 

the Run-15 performance. This is now almost a decade ago and we did not have too much practice since Run-15.

p+p is, however, less affected by the SEY de-conditioning we have seen with Au+Au.

 

The impact of the early termination of Run-23 is not yet fully reflected in the document in case a Au+Au mode is added.

 

Please distribute as needed, and let me know if you need any further information.
