Yes, but that is only on the *mass difference* with the B-mass as reconstructed by us, right? Ciao, - Marcel

Hi Marcel,
I think I remember that the very small uncertainty on masses is due to the q-value being tiny. The momentum resolution is (should be) given in the section on the detector. I did not redo the maths, though.
Cheers,
Patrick

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?
