[Clascomment] [EXTERNAL] Re: OPT-IN:Differential cross sections for Î(1520) using photoproduction at CLAS

[Igor Strakovsky]

Hi Valery and Authors,

Let me draw your attention to the fact that the detail study of the L(1520)
form was published a while ago. We used Hall A kaon electroproduction data.
BTW this paper reported the first Hyperion pole determination

\cite{Qiang:2010ve}
\bibitem{Qiang:2010ve} Y.~Qiang, Y.~I.~Azimov, I.~I.~Strakovsky,
W.~J.~Briscoe, H.~Gao, D.~W.~Higinbotham and V.~V.~Nelyubin, %``Properties
of the $\Lambda$(1520) Resonance from High-Precision Electroproduction
Data,'' Phys. Lett. B \textbf{694} (2011), 123-128
doi:10.1016/j.physletb.2010.09.052 [arXiv:1003.5612 [hep-ph]].

Cheers, Igor
