Abstract
Using two suitable benchmark scenarios that satisfy the experimental con- straints on the total decay width of the 125 GeV Higgs boson, we determine the bounds on light CP-odd spin-0 states in the 2HDM+a model that arise from existing LHC searches. Our work should prove useful for 2HDM+a interpretations of future ATLAS, CMS and LHCb searches for pseudoscalars with masses below the electroweak scale.

Strengths
Overall the paper is well written and presents a clear case for the suggested benchmarks.
Weaknesses
The work is interesting however it is not clear what is new in and different from earlier work such as ( arXiv: 1802.02156 or 1711.02110)
Report
The authors analyze constraints on a Two Higgs doublet model with an addition pseudoscalar (2HDM+a) from existing LHC searches. Specifically they propose two possible benchamarks that can be used in experimental analyses. The work is interesting however it is not clear what is new in and different from earlier work such as ( arXiv: 1802.02156 or 1711.02110) . The work is not novel enough to be published in Scipost Physics, but possibly in Scipost Physics Core.
Requested changes
1. The authors look at constraints from Higgs decays, how about the 4 lepton final states that would be relevant for larger masses of a (c.f. arXiv: 2107.00404)
2. Given the large branching ratio to b-quarks, there should be some comments regarding the low and high mass dijet searches. (c.f arXiv: 1802.06149 (Fig 4) and arXiv: 1801.08769 )
3. Minor: Typo on page 3 below equation 5 "...on $|g_{ahh}|$" assuming a light pseudoscalars a." should be "...on $|g_{haa}|$" assuming a light pseudoscalar a."
4. Minor Suggestion: Orange and red are not the best colours to choose especially when there are overlapping regions - Could you possibly change or improve this presentation in the two Figures (1 and 2 right).
