sPHENIX EMCal discussion

["Hodges, Anthony" <ahodges4 AT illinois.edu>]

Hi Blair, 

Thanks for the detailed feedback. I agree that the abstract could be clearer with regards to what's actually of interest in the poster, and I think adding a lot of physics references (jet suppression and direct photon measurements) only obscures things. Perhaps what's better is to reserve such commentary for the "Conclusion" or "Future Works" section of the poster itself. The new abstract is attached. 

"L9: as Justin presented on, we are not comparing to the PDG mass.  it's is simply a very well understood/modeled in-situ probe.  "

I relaxed the phrasing on this to account for what we discussed last week, let me know if it sounds reasonable. 

"L10/11:  combinatorically seems like the wrong here, maybe "Both pi0's and eta's are reconstructed through their two-photon decay by calculating the invariant meas between all EMCal cluster which satisfy a set of cuts optimized for highsingal to background ratio.  "

At least in the way I'm familiar with pi0 reconstruction, you do look at all combinatoric pairs of clusters that pass your single cluster cuts, but that word doesn't really add any information over "all pairs of clusters", so I removed it. You'd make an invariant mass cut if you were doing tagging, but if you're just looking for integrated yields, you can take all pairs and integrate regions of the invariant mass distribution. 

"L13/14: "where jet-energy loss effects aree expected to dominate."  I really don't know what you mean by this.  OK this is about physics "

Right, but also removed and presumed to be added to a different section of the poster. 

Further comments  are welcome!

Best, 

-Anthony

Hi Anthony,

Thanks for submitting something that covers our sub-groups work.  Below are some comments.

General comment:  I think you need to more cleanly state (or sepeerate) that we are doing calibrations with this and physics measurements with this.  I got confused whether you were making a calibration point or a physics point.  

General comment: You mention a lot of things (motivations and related works) that are related but do you plan to showw  things that are directly related to these motivations  you mentions?  For example, you mention rejecting high-pt pi0s for photon jet, do you plan on showing single photon purities at high-pT?  Might be better to be more specific about what exactly you plan to show and less specific about the motivations.   

L9: as Justin presented on, we are not comparing to the PDG mass.  it's is simply a very well understood/modeled in-situ probe.  

L10/11:  combinatorically seems like the wrong here, maybe "Both pi0's and eta's are reconstructed through their two-photon decay by calculating the invariant meas between all EMCal cluster which satisfy a set of cuts optimized for highsingal to background ratio.  

L13/14: "where jet-energy loss effects aree expected to dominate."  I really don't know what you mean by this.  OK this is about physics 

Best,

Blair

Good evening everyone, 

Thanks for all the helpful (and quick!) feedback both online and off! As suggested, I've shortened the abstract and fixed typos that were pointed out. Attached is the updated abstract, and further comments are welcome.

Best,

Good evening calorimeter and jet enthusiasts, 

I have prepared and attached a poster abstract for a poster on neutral meson analyses for this year's Quark Matter conference for your consideration. Comments and feedback are most appreciated. 

Best,
