[Clas_hadron] NSTAR Abstract

[burkert]

Hi Chuck,

You have a nice abstract of an important physics channel. I have only a 
couple of comments:

1) You may want to write the reaction gn->K_s Lambda better in this 
form  gD->K_s Lambda (p_s) < to make it clear that nuclear corrections 
have not been (fully) done to extract the cross section on the neutron.

2) You mention an increase of the cross section at central cms angle for 
2.2-2.4 GeV photon energy. It would be better to use the invariant mass 
W (2.24- 2.32 GeV) rather than energy as the interest is in resonances 
at fixed masses. I also wonder if this increase in cross section is the 
only interesting feature of the data. For example, don't you see a peak 
at a mass of ~1.9GeV, which is clearly seen in K^+Lambda production, and 
is likely associated with the P13(1900) state (now a *** state in 
PDG2012) ?  If you don't see this peak it would be very interesting as 
it tells us something about the photon coupling to neutrons for that state.

Best regards,
Volker
