Abstract
DarkSide-50 is a direct dark matter detection experiment at Laboratori Nazionali del Gran Sasso that uses argon as the target material. Exploiting the ionization signal from a dual-phase time projection chamber filled with low-radioactivity argon, it has set the most stringent exclusion limit on WIMPs with a mass of few GeV/c2. A new analysis has recently been carried out with a larger exposure, profiting from an improved under- standing of the detector response and background model. An improvement of about a factor 10 in sensitivity is expected for a WIMP mass of 2 GeV/c2.

Report
In this proceeding authors present the most stringent exclusion limit on WIMPs with a mass of few GeV/c2 after applying new analysis described here. The manuscript is clearly written and well organised. It is also suitably formatted for publication.
I recommend the manuscript for publication after adding references to other experiments for Fig.3.
Requested changes
Please add references to other experiments for Fig.3.

(in reply to Report 1 on 2022-10-02)Dear our reviewer,
Thank you very much for your report.
As you suggested, we add references to other experiments and neutrino floor for Fig.3.
Kind regards,
Masato Kimura
