sPHENIX cold QCD topical group

[Genki Nukazuka <nukadukagenki AT gmail.com>]

Dear all,

You can find the final version of the slides in PDF, .pptx, and .key as my talk was over.

https://sphenix-invenio.sdcc.bnl.gov/records/2jj6g-hz888?preview=1&token=eyJhbGciOiJIUzUxMiJ9.eyJpZCI6IjNhYjIyOGI4LWQwOTgtNDc0MC1hZjJhLWJlMDgxYTk4MDZhYyIsImRhdGEiOnt9LCJyYW5kb20iOiJhOWJhNmQ5NmVkNWVjY2YwYTU3YzUxNTM3YzZjOGZjNyJ9.KIy3LMXDcpkcicxLUrwpWYqXMKpCUjMyurHxPvKQ0CR14W2ZFG7Sror12cHjXvjMpPXq7WqVJSg5yKEU7HyNFg

The audience focused on the great results from ZCD/SMD.

There was comment on page 16: What was shown from STAR is π+π- asymmetry while the statistical projection of h+h- at sPHENIX was compared. This is misleading.

I agree with the comment. I have to be more careful.

Anyway, my talk was not too bad in my opinion. Thank you for your comments so that I could improve my slides.

Best regards,

Genki

Dear Ralf,

I'll be careful when showing the page.

Dear all,

The updated version is available on Invenio: https://sphenix-invenio.sdcc.bnl.gov/records/9ygns-bzp71?preview=1&token=eyJhbGciOiJIUzUxMiJ9.eyJpZCI6IjNhYjIyOGI4LWQwOTgtNDc0MC1hZjJhLWJlMDgxYTk4MDZhYyIsImRhdGEiOnt9LCJyYW5kb20iOiJhOWJhNmQ5NmVkNWVjY2YwYTU3YzUxNTM3YzZjOGZjNyJ9.KIy3LMXDcpkcicxLUrwpWYqXMKpCUjMyurHxPvKQ0CR14W2ZFG7Sror12cHjXvjMpPXq7WqVJSg5yKEU7HyNFg

For easy access, I also uploaded to BNLBox: https://bnlbox.sdcc.bnl.gov/index.php/s/aFHPQgDSjZADjdQ

To finish my talk on time, I needed to reduce the pages for the introduction about sPHENIX. Today, sPHENIX was also drastically changed to show the status of ZDC/SMD and INTT.

I'm happy to have your opinions.

Best regards,

Genki

Hi Genki,

thank you very much, so your first number was not 10% streaming but the
5kHz number. That makes more sense.

Cheers,

Ralf
