Zhang Jingxu:
1. Luminosity on page 13: 410 pb^-1 is not correct? See Cheng Liu's N_psi' paper
2. Page 21: It may be confused to give relative systematic uncertainties in this table and it is better to It is better to keep only two significant digits after the decimal for the absolute systematic uncertainties.
3. It may be better to keep the highest upper limit as the nominal result or mass window of M_ll or cut range of q_zz?
4. When combining the two channels of ee and mumu, you need to consider the correlated effects among them.
5. p10: the continuum background in the left top coner seems to come from radiative Bhabha. Please apply for both ee and mumu channel.
6. p11: the 2012 data pion tracking efficiency is quite different from other years. Please consider to use the psi(2S) data sample for tracking efficiency study.
7. p14: did you perform the same pi pi mass fit as Benhou's study? Did you use the fit results to generate your signal MC?
8. p21: the J/psi mass window cut and qzz cut are quite sensitive to your results. Consider estimate its systematic uncertainty in a better way.
9. p22: Is it possible to test other observables, such as q2, qee?
Che Guorong:
1. After KMFIT, the M_pipi^recoil is strongly correlated with M_pe, is it necessary to use 2D signal region?
2. Page 19: Why these distributions do not follow (0,1) distribution?
3. Please use the latest N_psi' from Cheng Liu.
4. Please check the E^max_extra gamma of the event and E/p cut for (anti)proton helps to suppress the backgrounds from pi+pi-J/psi with J/psi -> e+e-gamma.
5. p5: can you provide the e momentum distribution?
6. p8: the signal region definition is not good. try to define it in the diagnoal line or 1D distribution.
7. p8: Can you use the p/e momentum in pi pi recoil rest from to veto the remaining background?
8. p19: the pull distribution shows you are underestimate the uncertainty. Please improve.
Jiao Junkun:
1. The uncertaintaities of quoted BFs of Lambda and Lambda-bar should be added linearly.
2. It is better to keep only one significant digit after the decimal for the systematic uncertainties.
3. It is better to estimate the systematic uncertianties of Sigma^0 (-bar) mass window by using control sample
4. It is not clear how you estimate the systematic uncertainty due to data-MC discrepancey, which seems not so reasonable.
5. Have you estimate the systematic uncertainty due to PHSP MC model? or at least check the difference of the efficiency after re-weighting M_Sigma(-bar) omega spectra and your nominal efficiency?
6. Page 23: Have you consider systematic uncetainty when you estimate the significance of this structure? If its significance is only 2.5sigma, is it reliable to report the mass and width of this structure?
7. p5: anti-proton produce more fake photons than proton. please optimize the angle cut, i.e. 10 degree.
8. p9: how do you combine the photons?
9. p19: why choose the lower mass to study intermediate state?
Duan Yaoyu:
1. please give upper limit for channels with <5sigma significance.
