Hello Veronika

Thanks for addressing my comments. The new version looks very nice. I have only a few additional minor comments. 

RESULTS

- In Fig. 3, please remove the comma after "p_T" in the x-axis title

- function (Figure 4) -> function (Fig. 4)

- efficiencies (Figure 5) -> efficiencies (Fig. 5)

- Add "Au+Au \sqrt{s_NN} = 54.4 GeV" to both panels of Fig. 5

- In the left panel of Fig. 5, I suggest to use option "PL" in legend for the data points in different centrality bins, i.e. remove the colored box around data points in the legend, since you already have the box indicated as "sys. uncertainty"

Best

Hello Rongrong,

Thank you very much for your comments! I have implemented them and uploaded the new version under the new entry: https://drupal.star.bnl.gov/STAR/system/files/PosterQM23_Prozorova_ver2.pdf

Regarding your question about Figure 3. This behaviour is due to the cuts we are using for the electron identification. For pT < 1.25 GeV/c we use TPC and TOF, for 1.25 < pT < 1.5 GeV/c we use TPC, TOF and BEMC, for pT >1.5 we use TPC, BEMC and TOF hybrid mode to get more statistics. More information here: https://drupal.star.bnl.gov/STAR/system/files/HFE54.4GeV_6Apr2023.pdf

As it would take a lot of space to explain this behavior I added a small note regarding the BEMC only as it catches the eye the most.

Best regards,

Veronika

Hello Veronika

I was asked by the STAR management to take a look at your poster. Here are some comments for your consideration:

ABSTRACT
- Studying heavy flavor can -> Studying heavy-flavor production in heavy-ion collisions (HIC) can
- Quark-Gluon Plasma (QGP) -> Quark-Gluon Plasma (QGP) created in these collisions
- One way to study the production of heavy quarks -> One way to study heavy quarks

HEAVY-FLAVOR ELECTRONS
- semi-leptonic decays of open heavy-flavor hadrons
- It is a pT dependent fraction of electrons from both D and B hadron decays. -> Relative contributions of D and B hadron decays depend on electron p_T.
- As HFE have higher -> As semi-leptonic decays have higher
- remove "of open heavy-flavor hadrons"
- I do not think you need to introduce the concept of non-photonic electrons, which could cause confusion. I suggest to merge second and third bullets, and write Eq. (1) as: N^HFE = (N^incl * purity - N^PE/𝜀^PE)/(𝜀^total) - N^HDE
- total efficiency of identified electrons -> total efficiency of electron identification and reconstruction
- are hadron-decayed electrons: 𝜌 -> are hadron-decayed electrons from 𝜌
- e^PE sources -> N^PE sources
- remove "direct"

STAR DETECTOR
- study properties of strongly-interacting matter -> study properties of the QGP
- Particle momentum reconstruction and
- add an empty space after "dE/dx,"

PHOTONIC ELECTRONS
- are subtracted statistically from the inclusive electrons using invariant mass method -> are identified using the invariant mass method and subtracted statistically from inclusive electrons
- Figure 2, caption: PE pure sample for -> photonic electrons in
- 𝜋0 -> 𝜋^0 (0 should be the superscript)

RESULTS
- In Fig. 1, there are some distinct features: i) a bump around 1 GeV/c, ii) a sudden drop around 1.4 GeV/c, and iii) another bump around 1.6 GeV/c. Do you understand these features? Are they related to trigger bias? It will be good if you can add some explanations.
- Figure 1, caption: add a comma before "for"
- remove "In order to evaluate hadron contamination the"
- were fitted with multi-Gaussian -> are fitted with a multi-Gaussian
- (Figure 4). This is needed to -> (Figure 4), to
- Figure 4: add "Au+Au \sqrt{s_NN} = 54.4 GeV" to both panels
- TOF, BEMC -> TOF and BEMC
- calculated from data using pure photonic electron sample -> calculated using pure electron sample in data
- Figure 5, left panel: the legend indicates the systematic uncertainty is displayed as filled gray box, while I can only see open colored boxes around data points. Please make them consistent.

CONCLUSION
- Heavy-flavor electrons are a powerful -> Heavy-flavors are a powerful
- towards N^PE evaluation -> towards N^HFE evaluation
- v2 -> v_{2}
- add the reference to HFE v2 paper

REFERNECE
- Unify the reference style

Best
Rongrong
