Recent High Mass WIMP search results from DarkSide-50


Located at the LNGS, Italy, DarkSide (DS) is a dark matter search
project, which features a dual-phase Time Projection Chamber
as the WIMP detector, surrounded by an organic
liquid-scintillator neutron veto and a water-Cherenkov muon
veto. The current DS-50 has been taking data with Ar extracted
from underground sources (UAr) since April 2015. As of October
2017, the experiment accumulated 532.4 live-days exposure of
blinded data with the UAr target. In this talk, I will present the
recent blind analysis and the spin-independent dark
matter-nucleon coupling results. Various background studies will
be discussed, with an emphasis on a novel concept of
Cherenkov coincidence background. The Monte Carlo modeling
of the background predictions will be presented .
