[Eic-core-phys] [EXTERNAL] CORE SIDIS deliverables & next WG mtg.: Nov. 11, 9am Eastern (3pm CET 6pm Yerevan)

[Alexey Prokudin]

Hi Gunar,

I should be able to join on Thursday. Please, send the zoom link to me. 
I did not receive one for today's meeting.

Cheers,

   Alexei

> 3) SIDIS-variable distributions (in particular z, Phperp)
>     o effect of both  general acceptance and also of PID coverage
>     o ideally, do this in x-Q2 "bins"

> 4) closely related, resolutions of SIDIS variables, incl. also phi

> 5) impact I: statistical precision of SIDIS cross section in bins of
