[Clascomment] OPT-IN: Upper limits for the photoproduction cross section for the Phi--(1860) pentaquark state off the deuteron

[David Ireland]

Hi Hovannes et al.,

This is a nice paper. I picked up just a few points:

* p6, left col, para 2: You refer to "inefficiency", which I assume is "1 - efficiency". I'm not sure how clear this concept is to the reader.

* acknowledgements: Please add "United Kingdom's Science and Technology Facilities Council"

* p8, right col, three lines after eq. (4): there is a subscript "t" on \mu in the in-text equation, which is not in the denominator of eq.(4) - is this a typo, or have I misunderstood?

Cheers,

Dave
