Abstract
In this paper, the SharmaMittal Holographic dark energy model has been investigated in the framework of the ChernSimons modified gravity theory taking into account the FRW universe. We explored a number of cosmological parameters such as deceleration parameter, equation of state, the square of sound speed, and density using redshift parameter. The graphical behavior indicated \enquote*{$\omega$} decreasing approaching to $1$ for $1<z<0$ and increased for $z>0$. It advocated that the universe contracts, bounces and expands. The density parameter showed the decreasing behavior and converges to zero asymptotically, gives the condition that the universe will collapse ultimately at infinite time. It is also found that the square speed of sound turned to be positive for all parametric values predicted the stability of the system.

The paper studies the SharmaMittal Holographic Dark Energy Model within the framework of ChernSimons gravity. Without proceeding further to commenting on the quality of the paper, I would like to draw the attention of the editors and the authors to the following closely related paper:
M. Younas, Abdul Jawad, Saba Qummer, H. Moradpour, Shamaila Rani, “Cosmological Implications of the Generalized Entropy Based Holographic Dark Energy Models in Dynamical ChernSimons Modified Gravity”, Advances in High Energy Physics 2019(34):19, arXiv:1901.01311 [physics.genph]
A part of this paper is devoted exactly to the SharmaMittal Holographic Dark Energy Model in ChernSimons gravity and it is neither discussed nor even cited in the present manuscript. Even though the submitted paper is a bit more thorough than arXiv:1901.01311, it is clear the main results are not new. Therefore, I can not recommend the paper for publication.

The paper ”Analysis of SharmaMittal Holographic Dark Energy Model in ChernSimons Modified Gravity”
by Sarfraz Ali and Muhammad Hammad Waheed discuss a dark energy model in the context of SharmaMittal
holographic dark energy in modified gravity. I can not recommend publication for the following reasons:
1. There would exist the past related works for the SMHDE models in the literature. By comparing with these
preceding studies, the new ingredients and significant progresses of this work should be stated more explicitly and in
more detail. That is, the differences between this paper and the past ones should be described in more detail and
more clearly. This is the most crucial point in this review, which is missing.
2.  The figures of the deceleration parameter (DP), EoS and energy density parameter and other that the author
present are not realistic. For instance Ω at z=0 should be 1. The authors should be more careful when they write a
scientific manuscript.
3. Unfortunately paper contains only technical calculations of some cosmological parameters for the SMHDE
model in modified gravity. It appears to me that all of the paper become a simple mathematical exercise, with no
physical background.
In summary, I cannot recommend the paper for publication.

Dear Reviewers I found your valuable comments on our article "scipost_202005_00010v1". I try my level best to reply your precious comments. 1. SharmaMitall Holographic Dark Energy (SMHDE) has been studied in different modes such as "Generalized entropy formalism and a new holographic dark energy model"Physics Letters B Volume 780, 10 May 2018, Pages 2124. Exploring the Sharma–Mittal HDE models with different diagnostic tools (Eur. Phys. J. Plus 135, 391 (2020)). Tsallis, Rényi and SharmaMittal Holographic Dark Energy Models in Loop Quantum Cosmology, Symmetry 10(11):635 (2018). BUT non of them explored the model as we did first time. So there is no relevant COMPARATIVE study available in literature. Although, there is enough literature on Holographic Dark Energy models in the context of ChernSimons modified gravity which We add as references. 3.Every result is explained graphically as well as physically such as (i)The deceleration parameter q predicted that the universe is in decelerating and expanding phase known as a de Sitter expansion for $1<z<0$ and the expansion rate of the universe is increased at acceleration level for all $z>0$, which is same as a model developed by Johrami. (ii).It advocated that the universe contracts bounces and expands.
WE ADD PHYSICS AFTER EVERY RESULT. CONCLUSION IS ONLY PHYSICS OF THE ARTICLE.
So we request to reevaluate the article for the encouragement of the scientific studies.
