Abstract
Correlations between charged particles provide important insight about hadronization process. The analysis of the momentum difference between charged hadrons in pp, p-lead, and lead-lead collisions of various energies is performed in order to study the dynamics of hadron formation. The spectra of correlated hadron chains are explored and compared to the predictions based on the quantized fragmentation of a three dimensional QCD helix string. This provides an alternative view of the two-particle correlation phenomenon typically attributed to the Bose-Einstein interference.

Report
The Journal's requirements for acceptance are met.
The proceedings fairly reflect the presentation delivered at ISMD22, and I am happy to recommend publication. I have no detailed comments on the physics content.
I have just one general comment, below, and a few more specific comments (most are suggestions to do with grammar/typos, which which the author can take, if helpful), which I have put in the list of Requested Changes.
Comment:
-- Since these proceedings are on behalf of the ATLAS Collaboration, could the author confirm that they have been seen by the ATLAS publications committee, and signed off by them? I note a number of usual requirements that do not seem to have been met, e.g. notably, such proceedings should normally mention 'ATLAS' in the abstract, Intro, Conclusions, and ensure to cite the ATLAS detector publication etc. If this has not been done, please could the author get the proceedings checked within ATLAS before (re-)submitting a final version.
Requested changes
Minor comments/suggestions on grammar/clarity:
1.
o Abstract:
-- '...about the hadronization process.'
-- 'Analysis of the momentum...'
2.
o Introduction (p1):
-- '... modelling of confinement, replacing the 1-dimensional...'
-- '... into the rules governing hadronization.'
-- I am finding it difficult to parse the sentence starting 'There are several essential...' (in particular, the part after the colon). Are there supposed to be 'several' properties being described here? Could this part be reworded to improve clarity....?
-- add a caption (and reference to the figure in the text) for the illustrative figures on p1
3.
o Introduction (p2):
-- '... with a precision of 1--3%, with the help of...'
-- '... radius of the helix.'
4.
o Anomalous.... (p2)
-- '... where the rank...'
-- '... with the help of the observable...'
-- '... intrinsic pt of the direct pion...'
-- '... which eliminates the contribution from (the unknown) ... with the help of an additional ... of the fragmentation function...'
5.
o p3
-- Fig 1 caption: 'The bottom plots indicate...' (also $p_{\rm T}$
-- wounded -> wound?
-- '... instrumental in understanding long-range correlations...'
6.
o p4
-- Figure 2 caption: 'The blue area...'
7.
o p5
-- Figure 3 caption: the description of the figure in (a) should say it is as a function of Q for different selections on particle multiplicity (at the moment it reads as if it is as a function of particle multiplicity). Also, it would be better to restrict the caption to stating what is shown in the plot, rather than drawing conclusions in the caption, which would be better placed in the main text only.

Thanks for the text corections, they are implemented in the resubmission
(v3 on the arXiv). The contribution is approved as ATLAS proceedings
ATL-PHYS-PROC-2022-084. Some misunderstanding arised from the fact that the ATLAS approved version was posted as version v2 on arXiv, but not resubmitted explicitly to SciPost ( I wrongly assumed the updates would propagate automatically to SciPost submission).

This manuscript reports on the Helix string fragmentation study in Lund string fragmentation and charged particle correlations in pp, p-Pb, and Pb+Pb collisions with the ATLAS experiment. The literature of the paper is appropriate for a regular article SciPost Physics after addressing some further comments that I have listed below.
