Dear Veerle,

Here are my comments on the Dphi paper.

L.29: eigenstates L.33: "sufficient number of different D final states" could you say how many? L.122: larger than 0.2 is irrelevant to the reader as no distributions are given. Please remove. L.124: which assumptions on the BF? Why did you not use the Punzi FoM that avoids the problem? L.133: You decide not to use the information of whether you have a DbarK* or a DbarK*bar final state and hence are loosing information. With that info you would have 2 mass plots with the same B, resp Bs signal but half the background. Why don't you do that? Fig. 1: Bs->DbarK*bar (bar missing) L.173: is -> are L.201 and later : ^{bkg} -> ^{\rm bkg} L.226: could you explain why you have a fit bias? L.237-242: you account for DCS decays but not for double mis-ID which give you a broader D mass. How are they treated? Section 5: f_s/f_d should be in math mode. Are you using the latest error with the new CLEO measurement? "... compared to a previous measurement [20]" : If it's one measurement cite it and not the PDG.

Cheers,

Patrick
