UC Santa Cruz physicist Stefano Profumo has put forward two imaginative but scientifically grounded theories that may help solve one of the biggest mysteries in physics: the origin of dark matter. In ...

For decades, physicists searched for a missing piece of nature's puzzle, an elusive particle believed to explain why matter has mass. Nicknamed the "God particle", the Higgs boson became one of the ...

Two recent studies by Professor Stefano Profumo at the University of California, Santa Cruz, propose theories that attempt to answer one of the most fundamental open questions in modern physics: What ...

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 ...

Physicists have long been fascinated with dark matter. Scientists discovered that observable matter, stars, galaxies, nebulae ...

A philosopher has put forward an argument for rethinking how particles are defined within the standard model of particle ...

Neutrinos are one of the most elusive and omnipresent particles in the universe. Their strange properties may explain why the amounts of matter and antimatter in our universe aren’t equal, as most ...

In recent years, a curious hypothetical particle called the axion, invented to address challenging problems with the strong nuclear force, has emerged as a leading candidate to explain dark matter.
