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.

Anonymous Report 1 on 2022-10-2 (Invited 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.

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
