Dear Kosuke,
Nice slides. Please include the following minor comments. With these included I sign-off.

Title:
"Global polarization of Λ hyperons in Beam Energy Scan II at RHIC-STAR"
-->
"Global polarization of Λ hyperons in RHIC Beam Energy Scan II from STAR"

Everywhere:
"Abdallah, M. S. et al., PRC104.L061901 (2021)"
-->
"M. S. Abdallah et al. (STAR Collaboration)
Phys. Rev. C 104, L061901"


slide#7:
"vacuum pipe" --> "beam pipe"

slide#9 (everywhere)
"topological cut" --> "topological cuts"


slide#10:
"The increasing trend is observed at √s_{NN}=2.4 GeV to 5.02 GeV"
-->
"The increasing trend with the decrease of collisions energy persists down to √s_{NN}=2.4 GeV"


slide#13:
"One might expect ..." --> "Possible expectations:"
"No significant p_T dependence"
-->
"No significant p_T dependence seen in data"

Summary slide:
"We presented Λ global polarization"-->"We presented measurements of Λ global polarization"

"with fixed-target configuration" --> "from STAR in fixed target mode"

"There are no significant rapidity and dependences" --> "No significant dependence on p_T and rapidity observed"

Backup slide 16:
Put more information on the plots such as collision system, energy.

"Pile up events are removed using TOF start timing(T0)."
-->
"Pile up events are removed using start timing (T0) estimated using TOF and TPC"

"About 90% pile up events would be removed." Is this the right number ?
I am confused. We normally remove 0.5% of the events as pile-up. What is this 90% ?

slide #17:
Put more information on the plots such as collision system, energy.

"Extract the polarization signal"
-->
"Extraction of the polarization signal"


Best,
Prithwish
