[Clascomment] OPT-IN:Differential cross sections and recoil polarizations for the reaction gamma p --> K^+ Sigma^0

[David Ireland]

Hi Biplab et al.,

Nice paper, with impressive results. I just picked up a couple of points:

page 1, 2nd paragraph: There are just *four* complex amplitudes for K+Sigma0, so there are eight real numbers that represent them as a function of sqrt(s) and scattering angle. On the other hand, there are 16 observables, which are not independent. I know what you are referring to, but you may want to alter the language a little. 

page 10: I think the second equation is missing a number.

Cheers,

Dave
