Dear all,

See below my comments:

- In the abstract and conclusions it is written “Parameters of these structures are obtained…” This is quite vague. Could this be a bit more specific? For instance, mass and natural width of these structures are obtained…” or similar.

- L6-8: There is a small contradiction here. First, L is defined as a the relative orbital angular momentum of the two quarks, and then the total angular momentum of the light quark only is |L+-0.5|. In the heavy-quark approximation, there is only the orbital angular momentum of the light quark L. So, this can be fixed by defining L as the orbital angular momentum of the light quark in L6-7.

- L28: Suggest: “Due to the missing photon, the peaks from decays to B*pi are shifted …"

- Footnote: Replace Letter by paper.

- Fig. 1: Could you make these plots a bit bigger?

- Fig 1, caption: replace “fitted with a double Crystal Ball” -> “modelled with a double Crystal Ball”. To make it consistent with the rest of the sentence.

- Fig 1, caption: add dash in “second-order”.

- All plots: Make all text in normal font (not in bold). 

- L98: Suggest to smoothen: “… requires that the software trigger decision is based exclusively…."

- L103 and 105: Use the abbreviation “PV” here.

- L141: Remove “respectively”. It is not needed.

Cheers
Jeroen

Dear all, here are my comments on the paper.
I have two questions/comments (and I congratulate the authors):

The first is on shape of the AP-component, which  is justified on 
page 8 line 208-215. However, the motivation leaves a lot of 
freedom to chose any shape. What fraction of the AP-shape 
is the sixth-order polynomial based on MC and what fraction is 
the broad RBW  based on unmodelled fragmentation effects?
I can not judge it from looking at the shape in Figs 4 and 5.

Since the shape of AP might affect the parameters of the resonances 
in a different way in each of the three p_t bins I would like to see 
whether all the masses and widths give consistent results in case they 
are determined independently in each of the p_t bins. 

The second question is on the overall momentum/mass scale.
I presume the uncertainty of the overall momentum scale in the
values quoted on page 17 (line 298) is 0.17 MeV.
I'm surprised it is so small. Is this taken from another paper?

cheers,
- Marcel

Dear all,

As a reminder, the deadline is tomorrow. Did anyone read the paper already?
