Long-lived physics

New particles produced in the LHC's high-energy proton-proton collisions don't hang around for long. A Higgs boson exists for less than a thousandth of a billionth of a billionth of a second before decaying into lighter particles, ...

Solid start in the quest for an elusive particle

A collaboration of Belgian, French and British scientists, including researchers from Imperial College London, have developed a technology to detect a new kind of elementary particle: the sterile neutrino. The new detector ...

How does it look when Earth is bombarded with dark matter?

University of Southern Denmark researchers have conducted simulations of dark matter particles hitting the Earth. Physicists believe that Earth collides with uncountable dark matter particles as it hurtles through space. ...

Detecting cosmic rays from a galaxy far, far away

In an article published today in the journal Science, the Pierre Auger Collaboration has definitively answered the question of whether cosmic particles from outside the Milky Way Galaxy. The article, titled "Observation of ...

Video: Dark matter hunt with LUX-ZEPLIN

Researchers at the Department of Energy's SLAC National Accelerator Laboratory are on a quest to solve one of physics' biggest mysteries: What exactly is dark matter – the invisible substance that accounts for 85 percent ...

Finding neutrinos – a Q&A with Matthew Green

Matthew Green is an assistant professor of physics at NC State. He was involved in a multi-institutional research project aimed at detecting a process called Coherent Elastic Neutrino Nuclear Scattering (CEvNS). The project ...

Searching for invisible particles with the ATLAS Experiment

As the Large Hadron Collider (LHC) smashes protons at a centre-of-mass energy of 13 TeV, it creates a rich assortment of particles that are identified through the signature of their interactions with the ATLAS detector. But ...

Evidence of the Higgs particle's decay in quarks

As part of the ATLAS collaboration, the Freiburg research group led by Prof. Dr. Karl Jakobs and Dr. Christian Weiser has contributed to finding strong evidence that, among other things, the Higgs particle decays into quarks. ...

VENu makes it possible to watch a neutrino hunter at work

What happens when tiny, invisible particles called neutrinos are sent hurtling through a tank of liquid argon? For most of the neutrinos, not much. They'll pass through the argon unscathed. But other neutrinos will collide ...
