Why do we exist? This is arguably the most profound question there is and one that may seem completely outside the scope of particle physics. But our new experiment at CERN's Large Hadron Collider has taken us a step closer ...

The LHCb collaboration has spotted a new particle. Its mass and other properties place it squarely in the charmonium family that includes the better-known J/ψ particle, which was the first particle containing a "charm quark" ...

Neutron stars are among the densest-known objects in the universe, withstanding pressures so great that one teaspoon of a star's material would equal about 15 times the weight of the moon. Yet as it turns out, protons—the ...

Scientists widely accept the existence of quarks, the fundamental particles that make up protons and neutrons. But information about them is still elusive, since their interaction is so strong that their direct detection ...

The leading theory about how the universe began is the Big Bang, which says that 14 billion years ago the universe existed as a singularity, a one-dimensional point, with a vast array of fundamental particles contained within ...

Most physicists believe that the structure of spacetime is formed in an unknown way at the Planck scale, i.e., at a scale close to one trillionth of a trillionth of a metre. However, careful considerations undermine this ...
