Dark Universe

LUX-ZEPLIN (LZ) is a direct dark matter detection experiment currently operating at the Sanford Underground Research Facility (SURF) in Lead, South Dakota. It uses the world’s largest dual-phase xenon time projection chamber, with 7 tonnes of active xenon, primarily to look for dark matter in the form of Weakly Interacting Massive Particles (WIMPs). LZ has released its first WIMP search...

Dark Universe

A rich number of astrophysical and cosmological observations indicate the existence of a massive, non-luminous and non-baryonic matter component which is commonly referred to as dark matter (DM). One well motivated class of DM are weakly interacting massive particles (WIMPs) which arise naturally from several beyond-Standard-model theories.
The XENON dark matter project aims for the direct...

36. Directional detection of WIMPs with MIMAC

Dark Universe

Directional detection is the only admitted strategy for the unambiguous identification of galactic Dark Matter (DM) even in the presence of an irreducible background. The directional detection strategy relies on the simultaneous measurements of the energy and the direction of a DM-induced nuclear recoil, and on the correlation of the recoil direction with the expected incoming WIMPs direction....

Dark Universe

Inflation is now very well motivated because it can solve many issues of the Big Bang scenario. Specific models of inflation can be tested by observations, most notably by the CMB anisotropy power spectrum. I will present results on (dark) matter production in the late time evolution of this inflationary field usually called "reheating", and the challenges to probe these mechanisms. Especially...

44. The interactions and the possible probes of a light scalar dark matter

Sreemanti Chakraborti

Dark Universe

We study a minimal model for a light scalar dark matter (DM) with a mass of a few GeV, requiring a light dark photon mediator to interact with the Standard Model (SM) particles. We analyse the model by focusing on the Breit-Wigner resonance for DM annihilation channels, considering the thermal relic abundance condition that includes the early kinetic decoupling effect. The interactions of the...
