General ------- * [A general theoretical motivation is lacking. The intro of [2] can be an example?] Abstract -------- * [it is unclear that the 3rd unc effectively is the production asymmetry. How about:] 'and the third is the uncertainty on the B+- production asymmetry, driven by the knoweldge of ACP(B+->J/psiK).' 1 Intro ------- L.15 [a 'publication' cannot measure, how about:] 'but did not include a measurement of its asymmetry [3].' 3 Signal -------- L.108,112 [Is the fraction of part.reco background relevant? It strongly depends on the size of the mass window? What is the mass window?] L.115,125 [An exponential does not have a slope, but an exponent?] Fig.2: [Please add the charge of the final state particles to the labels!] Tab.1 [The last row suggests this is the result of the fit to the full sample. Instead it is the simple sum of the rows above. I suggest to remove the 3rd row.] 4 ACP ----- L.130 'physical' -> 'final' L.131 'have an even number or zero kaons' -> 'have two or zero kaons' Eq.(3) [The left-hand side is not A^raw_CP! Please remove subscript 'CP'. ] L.150 'where the statistical uncertainties' -> 'where the uncertainties' Tab.2 [The '0.016' and '0.020' in the last row 'Total' seem to be reversed!?] 5 Syst ------ Fig.3 [What is the horizontal band in the right figure around mKpi^2 = 10 GeV2 ?] 6 Phase space ------------- Fig.5 [caption: you mention twice m2<15 GeV2; one of them must be wrong. I suggest you also indicate this cut inside the figure.] Fig.6+8 [Add the legend for the empty/full triangles in the figure.] L.221 [Please motivate why you select m_high>15, as you do for m_low<0.4. Maybe you can also indicate that region in Fig.3 left.] Refs ---- [6] Physics Letters -> Phys. Lett.
