Search for dark matter annual modulation with DarkSide-50 Open
Dark matter may induce an event in an Earth-based detector, and its event rate is predicted to show an annual modulation as a result of the Earth’s orbital motion around the Sun. We searched for this modulation signature using the ionizati…

Reconstruction of 400 GeV/c proton interactions with the SHiP-charm project Open
The SHiP-charm project was proposed to measure the associated charm production induced by 400 GeV/c protons in a thick target, including the contribution from cascade production. An optimisation run was performed in July 2018 at CERN SPS u…
