General Meson SF Meeting Summary 5/10/21

PARTICIPANTS: Ali Usman, Carlos, David Richards, Rolf Ent, Garth Huber, John Arrington, Yulia Furletova, Paul Reimer, Tanja Horn, Richard Trotta, Stephen Kay, Tobias Frederico, Cynthia Keppel

REMINDER OVERALL GOALS 2021: Link

SECOND BEAMLINE DESIGN (Yulia, Rolf)

• Working on 2nd IR (IP8) design

• Integrated 2nd IR into overall EIC fulfilling boundary conditions, e.g. crossing angle not too large and not too small
• Two configurations with different crossing angle
• Ongoing work: fold in secondary focus within lattice space, optimizing acceptance for charged and neutral particles simultaneously (requires offsetting/moving magnets and checking optics acceptance - making sure that have a well matched and consistent lattice)
• New version of lattice received, need to check tracks, then could start checking acceptances

• IR6: working on implementation in dd4HEP

• Fine tuning with detector technology details

LATTICE AND GLOBAL FITTING (David)

• Patrick working on applying global fitting framework to data obtained from lattice calculations

• Might give constraints for global fits on gluon PDFs

CONTINUUM CALCULATIONS (Tobias)

• Continuing pion PDF and also TMD calculations beyond valence ongoing -

PION STRUCTURE FUNCTIONS (Richard)

• working on t-dependence evaluation

• next: kaon SF model

KAON FORM FACTOR (Stephen)

• Event generator being prepared to evaluate events in different frameworks - start with pions and then switch to kaons

NEXT MEETING: MONDAY JUNE 7 AT 4:00PM ET
