The XENON collaboration is seeking to directly measure weakly interacting massive particles (WIMPs) using liquid xenon time projection chambers (TPCs) of increasing target mass. The current stage, XENON1T, utilizes 3.2 tons of ultra-pure liquid xenon and has collected more than 1 ton x year of exposure. This dataset allows unprecedented sensitivity on the WIMP-nucleon cross section and new...
DarkSide uses a dual-phase Liquid Argon Time Projection Chambers to search for WIMP dark matter. The talk will present the latest result from the current experiment, DarkSide-50, running since mid 2015 a 50-kg-active-mass TPC, filled with argon from an underground source. The next stage of the Darkside program will be a new generation experiment involving a global collaboration from all the...
I will provide a unified presentation of extensions of the Minimal Dark Matter framework in which new fermionic electroweak multiplets are coupled to each other via the Standard Model Higgs doublet. I will discuss an estimate the parameter space for viable dark matter candidates including an estimate for the Sommerfeld effect. I will also argue how the coupling to the Higgs can bring the...
A review of the recent results obtained by the ATLAS Collaboration in the search for Dark Matter signatures in events with an high-pt Standard Model object recoiling against MET.
A short summary of the theoretical framework for DM searches at colliders is included.
The origin and nature of the dark matter in the Universe is one of the most pressing questions in fundamental physics. However, despite the enormous experimental effort no conclusive hint for a weakly interacting massive particle (WIMP) has been found, putting pressure on the widely considered WIMP dark matter explanation. In this talk we examine new avenues beyond the standard WIMP picture....
