[Jef] [External] Minutes for 11/13/20 JEF meeting

[Igal Jaegle]

Thank you, Liping, for your comments. Yes, I did require a recoil proton. The contribution of the non-resonant double pi0 is probably wrong as what I did for these figures is to fit the MC simu to the data but the relative difference between the different eta decays is fixed and correspond to their branching ratios.  I will add to my to do-list extracting non-resoant double pi0 production from data.

tks ig.

Hi, Igal,

I saw your simulation on 4-gamma eta decay channel with FCAL-II. The non-resonant double pion0 background looks high. Did you require a recoil proton to tag eta?

On the other hand, it would be great if you could extract non-resonant double pion0 production from data directly to check our generator for this channel.

Cheers,
Liping
