New Portal to Unveil the Dark Sector of the Universe

Portals can allow the exploration of the dark sector with the Standard Model particles Portals mix or connect the dark sector particles with the Standard Model particles. Through the portals it is possible to explore the dark sector particles using the Standard Model particles. The portals play a basic and critical role in the study of the dark sector particles both theoretically and experimentally. Credit: Image courtesy of Institute for Basic Science

Once upon a time, the Universe was just a hot soup of particles. In those days, together with visible particles, other particles to us hidden or dark might have formed. Billions of years later scientists catalogued 17 types of visible particles, with the most recent one being the Higgs boson, creating the ‘Standard Model’...

One of the biggest puzzles in physics is that 85% of the matter in our universe is “dark”: it does not interact with the photons of the conventional electromagnetic force and is therefore invisible to our eyes and telescopes. Although the composition and origin of dark matter are a mystery, we know it exists because astronomers observe its gravitational pull on ordinary visible matter such as stars and galaxies.

Some theories suggest that, in addition to gravity, dark matter particles could interact with visible matter through a new force, which has so far escaped detection...
