DOI: 10.1007/jhep03(2020)025
Abstract: A search for dark matter (DM) particles is performed using events with a Higgs boson candidate and large missing transverse momentum. The analysis is based on proton- proton collision data at a center-of-mass energy of… read more here.

DOI: 10.1088/1475-7516/2018/07/061
Abstract: A key prediction of the standard cosmological model -- which relies on the assumption that dark matter is cold, i.e. non-relativistic at the epoch of structure formation -- is the existence of a large number… read more here.

DOI: 10.1103/physrevlett.123.181802
Abstract: We report direct-detection constraints on light dark matter particles interacting with electrons. The results are based on a method that exploits the extremely low levels of leakage current of the DAMIC detector at SNOLAB of… read more here.

DOI: 10.1103/physrevlett.130.171003
Abstract: We report constraints on sub-GeV dark matter particles interacting with electrons from the first underground operation of DAMIC-M detectors. The search is performed with an integrated exposure of 85.23 g days, and exploits the subelectron charge resolution… read more here.
