[clas12_rgk] RGK slides

[Daniel Carman]

Annalisa,

Your last slide showing the e’K+ missing mass with the electon in the ECAL does not show the
RG-K data in its best light. If you look at the full set of the available 15 runs from the RG-K
data set at 7.5 GeV, the statistics are much better for highlighting the quality of the data and
show much better resolution than what you have in your plot. I attach what I have from my
ongoing analysis of the 7.5 GeV data from RG-K. Here the electron is detected in the ECAL
and I am looking only at the e’K+ topology with the K+ in the Forward Detector.

Regards,
Daniel

Dear All,

As agreed, I have started to extract the slides from the CLAS collaboration meeting which could be shared among the speakers of upcoming conferences.

You may find them at the link:

I am in doubt about the last one because of the low statistics and the spurious peak at the neutron mass, which must come from miss-identified kaons (actually pions).

Let me know your opinion: Steffen would like to present some slides at the APS meeting.

Al the best

Annalisa
