[Clascomment] OPT-IN: Beam-Spin Asymmetry in semi-inclusive electro-production of a hadron pair

[Volker Burkert]

Dear Marco and lead authors! 
This is a very nice and pioneering results and certainly worth to be published it PRL. It is also well written. I have only one request. In ref.[34] you refer to the corresponding experiment with CLAS12 and you refer to the proposal. Since the CLAS12 NIM paper is now published it would be appropriate to also refer to that NIM paper:  Nucl.Instrum.Meth.A 959 (2020) 163419. 

Thanks. Volker
