A New Theoretical Framework Outlining a Mechanism of Elementary Thermal Dark Matter

Astrophysicists have been trying to find dark matter for a number of a long time; however, these searches have up to now yielded disappointing outcomes. In a current examine, two researchers at Weizmann Institute of Science and the Hebrew University of Jerusalem in Israel have launched a new theoretical framework outlining a mechanism of simple thermal dark matter with a mass as much as 1014 GeV.

The dark matter thought-about of their work consists of a number of almost degenerate particles that scatter within the nearest-neighbor chain in a way that’s aligned with the usual model utilized in dark matter research. The brand new framework offered by these researchers, outlined in a paper published in Physical Review Letters, may, in the end, inform future searches for heavy dark matter. The particle that’s regarded as a great dark matter candidate, often known as a weakly interacting huge particle (WIMP), may very well be produced naturally from interactions between normal mannequin particles within the early universe, whereas they’re in thermal equilibrium. This specific course goes by the identity of the ‘thermal freeze-out mechanism.”

The brand new framework developed by Kim and Kuflik may have vital implications for research investigating the cosmic microwave background, construction formation, and cosmic rays. As well as, it might function as a benchmark for heavy dark matter experimental searches because it means that decays to ordinary matter particles within the late universe might depart attention-grabbing astrophysical and cosmological signatures, which researchers might search for when trying to find dark matter.

To this point, Kim and Kuflik have described the essential concept of superheavy dark matter and supplied an ‘easy toy model’ of it by parameterizing the interaction strength between dark particles and standard model particles.
