The particle in question, known as a sterile neutrino, was supposed to only interact with gravity and have zero interactions ...

A proposed funding program for small- and medium-scale projects reveals insights into the science, logistical challenges, and future of particle physics research. Particle physicists have a reputation ...

The universe's matter-antimatter asymmetry, where matter significantly outweighs antimatter despite their theoretically equal creation at the Big Bang, remains a major unsolved problem in physics.

"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of physics.

After years of searching, scientists at the Micro Booster Neutrino Experiment have ruled out the possibility of the existence ...

The neutrino “fog” is beginning to materialize. Lightweight subatomic particles called neutrinos have begun elbowing their way into the data of experiments not designed to spot them. Two experiments, ...

Andrea Gallo Rosso is a member of the ALPHA collaboration. He receives funding from the Swedish Research Council. Several experiments have aimed to unveil what it’s made of, but despite decades of ...
