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 ...

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 ...

Scientists working at CERN’s Large Hadron Collider may be seeing the strongest hints yet of physics beyond the Standard Model — the decades-old theory that explains the fundamental particles and ...

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 ...

From mysterious dark matter to the radioactive decay of atomic nuclei, the past 12 months have reiterated just how strange particle physics can be. When you purchase through links on our site, we may ...

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 ...

A study by Dartmouth researchers proposes a new theory about the origin of dark matter, the mysterious and invisible substance thought to give the universe its shape and structure. They say the ...

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.

Now is a surreal time to be a dark matter researcher. Even as research funding is being cut by governments around the world, dark matter remains one of the biggest and most exciting open problems in ...

Dark matter can't be too heavy or it might break our best model of the universe, new research suggests. We have an abundance of evidence that something fishy is happening in the universe. Stars orbit ...
