Probing Compressed Baryonic Matter

Round 1

Reviewer 1 Report

This is a good review article with a lot of information. It has presented both experimental data and theory and their interplay in pushing our knowledge envelope. I've a few comments (most of them are organization/language),
1. Line 24: (EOS) up --> (EOS) of up
2. Lines 46-47: experimental is used twice. Once is enough.
3. Line 54: Ref. [8] and not [8[
4. Line 55: microscopic-decrees-of freedom --> microscopic degrees-of-freedom
5. Line 115: delete second instance of experimental
6. Line 123: net- baryon --> net-baryon (remove space after hyphen)
7. Fig 3 caption is shifted
8. Line 158: hast --> has
9. Line 305: exist --> exists
10. Line 333: where --> were
11. Line 341: define CBM at first instance (already done in pg 1 abstract)
12. Fig. 5 caption should be below it
13. Line 365: what is RPC? Resistive plate chambers? Please define
14. Line 381: (RICH) in in parking --> (RICH) is in parking
15. Line 398: Did you mean 5 seconds? The very short time of 5 seconds and page break makes it confusing.
16. Fig. 8 caption should be at bottom.
17. Fig.9 caption is displaced.

Thank you very much for the  carefull reading. You may have got a version of the manuscript with a slightly different layout with shifted line numbers and displaced figure captions. Nevertheless, I have corrected the text according to your remarks.

Reviewer 2 Report

This review article contains several sensitive observables closely related to the (isospin dependent) equation of state (EOS) at high baryon densities up to 5 times saturation density as well as the latest progress of CBM facility at FAIR. The author is one important expert right in this field and describe them in good structure and depth. I agree to publish it in the journal Universe. Please verify the following minor typos before publishing.
1, page 2 line 60, ''decrees'' might be ''degrees''.
2, page 4 line 141, the subscript ''sim'' might be ''sym''.
3, page 5 line 168, ''hast'' might be ''has''.
4, page 15 line 555-557, the author list is not complete, please add them all, or, use ''et al''.

In addition, the following are suggestions for your consideration.
1, in the second section when talking about the extracted values of K_{nm} of EOS from different observables, although the current discussion has a good logic, I suggest the author to review more results, if possible, from other groups since this is one review article. Further, more comparison work with different groups is also required for readers.
2, page 4 line 143, in the sentence ''These values for Esym have to be added to the EOS for symmetric matter'', here the word ''symmetric'' might be changed to ''isospin asymmetric'' or ''nuclear'', or, delete '' for symmetric matter'' at all since the EOS will be not for the symmetric matter any more if the E_{sym} is considered.
3,  originating from the sentence in page 5 line 160, is that possible to have a short talk about the possibility of the measurement of free neutrons with the new facility? It is quite important to extract E_{sym} at densities from low to high densities.
4, since there is no citing reference for observable with hyperons in the second paragraph of page 5, here I suggest one since in this article the authors suggested the observable quite early, in Phys. Rev. C 71, 054907 (2005).

Reviewer 3 Report

The author in the present work review briefly the mission of the Compressed Baryonic Matter experiment at the future Facility for Antiproton and Ion Research (FAIR) in Darmstadt. These studies directly related with the investigation of the properties of strongly interacting matter, especially at very high densities. Actually, this is on open problem and all the relevant theoretical and experimental studies are expected to shed light on the structure, composition and basic properties of dense nuclear matter. Moreover, this issue related with the recent observation of gravitational waves of binary neutron stars system. The combination of the terrestrial experiments with the astrophysical observation are going to improve, if not finalize, our knowledge of super-concentrated matter. I consider that the present work, is in this direction and consequently, I recommend its publication in its current form. As a minor revision I suggest the author to make an effort, if it is possible, to improve the quality of figure 7.

Dear reviewer,

thank you very much for your comment. Unfortunately, I dont have figure 7 in a better quality. I will check with the editor, and might replace the plot by another figure with better resolution.
