General Meson SF Meeting Summary 9/19/24

Back to --> Material and Summaries

PARTICIPANTS: Garth, Love, Yulia, Tanja, Carlos Ayerbe, David, Gianni Salme, Rachel, Avnish, Tyler, Rolf, Craig

David Richards

• Gluon distribution in proton, pion, etc.

• pending labor 6 months to 12 months

Avnish (for Richard, Tyler, Rachel) - event generators

• Include Lambda in event generator studies studies (Rachel, Tyler)

• How is the link made with detectors? - see Yulia point below

• Action: work together with Yulia

Yulia - evaluation of detectors

• reminds of studies of ZDC benchmarking with Lambda and Sigma0

• Need to pinpoint the vertex - what detectors work for the science

• Planning to work with two highschool students to work on Monte Carlo samples

• Action: work together with Richard/Avnish/Tyler/Rachel

Craig

• Aspects related to TMDs - recently published

• Proton gravitational form factor and pion gravitational form factor

• Pion central pressure is greater than proton central pressure and both are larger than pressure in neutron star

• what happens with heavy quarks? Kaon pressure bigger than pion pressure, and so on
• working on it - maybe ready on a month or so

• Onset of scaling in pion and kaon fo

rm factors; expectations of break away from scaling; existing lattice studies are not precise enough to expose this

Patrick

• Additional hadronic data for constraining the splitting function in the meson analysis

• two observables depending on the splitting function and two on PDF

• Analysis on the kaon - also using hadronic data to constrain models

• Looking at available DY kaon data - explore kaon PDFs

Huey-Wen

• Impact of lattice on global analysis

• Revisit kaon PDF in context of combining with global analysis

Love Preet (for Stephen, Garth)

• Feasibility studies of pion electroproduction through ePIC simulations

NEXT MEETING: 17 OCTOBER 2024 AT 9AM ET
