A new theory for the origins of dark matter suggests that fast-moving, neutrino-like dark particles could have decoupled from Standard Model particles far earlier than previous theories had suggested.

In 1930, a young physicist named Carl D. Anderson was tasked by his mentor with measuring the energies of cosmic rays—particles arriving at high speed from outer space. Anderson built an improved ...

Wondering whether whether Dark Matter particles actually are produced inside a jet of standard model particles, led researchers to explore a new detector signature known as semi-visible jets, which ...

The magnetic moment of the muon is an important precision parameter for putting the Standard Model of particle physics to the test. After years of work, the research group led by Professor Hartmut ...

Red lines show the disintegration of a B-sub-s into two muons in the CMS camera at the Large Hadron Collider. Yello, green and blue are used to denote particles other than muons. Purdue University ...

The magnum opus of particle physics is far from complete, requiring physicists to devise many alternatives—some weirder than others. Reading time 5 minutes For all practical purposes, the Standard ...

Researchers have proposed a whole new way to search for dark matter. A team wants to use CERN’s Large Hadron Collider to look for what are called semi-visible jets”—columns of decaying particles that ...

A graphic representation of how semi-visible jets will appear in the ATLAS detector, should they exist. The existence of Dark Matter is a long-standing puzzle in our universe. Dark Matter makes up ...

Ian G. McCarthy receives funding from UKRI's Science and Technology Facilities Council (STFC). He works for Liverpool John Moores University. Given how unfathomably large the universe is, it is ...
