[Clascomment] OPT-IN: Double K0_S Photoproduction off the Proton at CLAS

[Stepan Stepanyan]

- p2, photon tagger range is from 20% to 95%, not 90%
- p2, left column, last line, CLAS momentum resolution is >0.5% not less
- p2, right column, 1s and last paragraphs, definition of scintillator counters, should be made the same. In one case it is "scintillator bars" in the another "Time-of-Flight counters"
- p2, right column, 2nd sentence "produce the particle tracks", photon dos not produce particle tracks, perhaps it should be "particles in CLAS"? particles are produced from photon, then they leave tracks in the detector
- p3, left column, where t_vertex wast taken, how it was calculated, is it from photon as other tagged photon experiments? if so, then was the t_vertex recalculated if photon selected from missing mass cut was not the one that cooking code used to calculate t_vertex
- p3, fiducial cuts, reason for fiducial cuts given is wrong. Fiducial cuts are due to DC when tracks go close to the end-plates
- p4, left column, it is may better to say "under the K_S peak" instead of "below the K_S peak"
- p6, left column, conclusion for Fig.7 about E>2.7 GeV, large W, and bayron resonances is not correct, even E>2.7 it is still possible, as explained for the background, that one of K_S will be produced in the t-channel, while other will come from some hyperon decay. The W is not necessary the resonance mass in this case, it is not fully s-channel production. For hyperon production, will be interesting to look different t, from one of K_S.
