[Halld-physics] Physics Working Group Meeting: Tuesday, October 16 @ 11:15 am

[Igor Strakovsky]

Hi Justin,

It would be good to spell out a possible Eg range and our goals for summer
of 2019.  Then all depends.

I reported twice that if our range is limited by 4 - 6 GeV and our main
goal is diff cross sections then
g12 from CLAS6 will work for us.  There are no CLAS pol measurements in
this case.  So, we have
gp-->pi0p cross sections published several month ago and Volker's analyses
for gp-->etap and
gp-->omegap are under the HW group review now.

If one can possible to go below 3 GeV then we will have more options
including polarized
measurements. Additional benefit will come from the ability to use the PWA
technology to evaluate
new data and possibility to provide "good" event generators for MC.  See my
slides at DB

Cheers, igor
