Understanding the universe's building blocks, the Standard Model categorizes particles and explains forces, yet leaves ...

String theory attempts to unify all forces and particles in the universe using vibrating strings. It aims to explain the Standard Model of particle physics, which is incomplete. String theory predicts ...

In nuclear beta decay an up quark ‘u’ in a proton converts into an up down quark ‘d,’ turning the proton into a neutron and emitting a positron and a neutrino. This work affects interpretation of beta ...

Physicists claim they may have found a long-awaited explanation for dark energy, the mysterious force that's driving the accelerated expansion of the universe, a new preprint study hints. Their ...

In the search for new particles and forces in nature, physicists are on the hunt for behaviors within atoms and molecules that are forbidden by the tried-and-true Standard Model of particle physics.

Particle physics describes the universe at the smallest scale. This includes subatomic particles, like protons and neutrons, as well as elementary particles, like quarks and electrons, which make up ...

What do quarks, electrons, and photons have in common? They’re all part of the Standard Model - the theory that helped ...

IN ARIZONA, AT Kitt Peak National Observatory, a telescope has spent three years building a three-dimensional map of the heavens. In examining the light from tens of millions of galaxies, the Dark ...
