Dear Manish

Abstract :
Better not to use present the preliminary results of the physics analysis dedicated. it is highly misleading.

Write something like : "We present preliminary MC study of the $B^\pm \rightarrow D^0(K_S^0 \pi^+ \pi^-) K^\pm$ to extract $\phi_3$ at the Belle II along. We discuss here the improvement in $\phi_3$ measurement one may expect at Belle II with 50 ab$^{-1}$. We also present preliminary reconstruction of the $K_S^0$ and $D^0 \to K_S^0 \pi^+ \pi^-$ using the Phase II data. "

Please write all equations in mathmode

$B^\pm \rightarrow D K^\pm$
$b \rightarrow c \bar{u} s$

Also write B, D as $B$, $D$

Please don't write "physics analysis of B -> D K"

Page2
In this work, the experimental facility Belle II at SuperKEKB is used....... --> In this poster, we present the preliminary MC study of B -> D K to extract $\phi_3$ using the 50 ab^{-1} data to be accumulated by the Belle II detector.

figure 2 --> Fig. 2 (same everywhere)

Fig. 2 UT fit today --> Current CKM fit (CKM2018) [give reference]

Explain Dress rehearsel data (it is Belle II jargon)

Put Belle II reference again when you mention the improvement due to CDC TOP and ARICH.

Ks should be written as $K_S^0$

Belle II has collected 478 pb^{-1} .

Recently, Belle II successfully completed its Phase II and collected 478 pb^{-1}. However, when the poster was shown, available data was 250 pb^{-1}. Therefore, the plots here are with 250 pb^{-1}

Page 3
Remove " The physics analysis of B.... at 250 pb^{-1}" This line is misleading. Please remove it. Further, you are showing Ks, D reconstruction. You have not shown the extraction of phi3 here. So, it is better not to use physics analysis.

Summary
Again " In this work, we have performed the physics analysis of B -> D K with Phase II data " remove the line.

That's all for now. Looking forward for updated draft.

Thanks

I made typo. I suggest you to please use the Prasanth's abstract

"
The dominant method to extract the CKM angle $\gamma/\phi_{3}$ at the $B$ factories is via a GGSZ type analysis. The golden mode to perform this type of analysis is $B^{\mp} \to DK^{\mp}$, where the $D$ meson decays to a self-conjugate final state $K_{S}^{0}\pi^{+}\pi^{-}$. The $\phi_{3}$ sensitivity is expected to improve significantly with a data sample of 50 ab$^{-1}$ from the upcoming Belle II experiment. Here we present the expected $\phi_{3}$ sensitivity from $B^{\mp} \to D(K_{S}^{0}\pi^{+}\pi^{-})K^{\mp}$ mode as well as the preliminary results using the data from the phase 2 of the Belle II experiment.
"

Thank you

Dear Manish,

Title: You need to add in bracket "On behalf of the Belle II Collaboration".

Name: Change my to "K. Prasanth". For FPCP2018, my affiliation was still TIFR.

You and Kavitha are from same institute, so 1 for MNIT. Other two insititutes then become 2 is KEK and 3 is TIFR.

Abstract: These are not the preliminary results of your analysis. You need to change the lines in the abstract something like "We present the preliminary results of phase 2 of the Belle II experiment giving emphasis to the extraction of \phi_3..."
Remove the sentence "In this work..."

Further, these results are compared with the Dress rehearsal data -> something like "We also compared the performance with Belle II Monte Carlo..."

Section 1: Introduction:

decaying to a three-body final state such as Ks pi pi -> decaying to different final states such as Kpi, KK, Kspipi {\it etc}.

Write equations in math mode within .

Change the full sentence "As the sensitivity.." to something like "The angle \phi_3 can be extracted by exploiting the interference between the Cabibbo-favoured and doubly-Cabibbo-suppressed $B$ decays..."

Various methods -> give reference to GLW, ADS

Dalitz plot analysis -> GGSZ method (write with a reference)

LHCb -> Collaborations

is required to measure \phi_3 -> is required to measure \phi_3, as the measurement is dominated by the statistical uncertainty.

collider [9], KEK-> asymmetric $e^{+}e^{-}$ collider [], will accumulate the collision data...

sec^{-1} -> s$^{-1}$

Change Fig. 2 to Belle toy result of B \to D(Kspipi)K that gives about 3 degree sensitivity and modify the corresponding sentence accordingly.

Kshort should be $K_{S}^{0}$

Mention what is phase 2.

Physics Analysis of B → DK -> "Preliminary results from phase 2 data"

Rewrite the paragraph in Sec. 2 by saying only Ks reconstruction and the comparison with Belle II Monte Carlo (MC) sample. Mention about the very good agreement of mass resolution. Then write about D \to Ks pi pi inclusive decay with a plot, followed by D* \to D(Kspipi)pi reconstruction (M_D & DeltaM plots). Then mention about the DeltaE, Mbc for B reconstruction. May be you can add the \DeltaE & Mbc plots which show that we have about 100 B candidates from different modes.

Summary:

the precision measurement of φ3 -> a substantial improvement in the precision of \phi_3 with the full 50 ab^{-1} data sample.
Reduce the remaining sentences to one or two with important points.
