Various constraints on the lifetime of the proton. Existing constraints are in solid colors and potential future constraints are shown hatched. Credit: Peter Denton and the American Physical Society, ...

A subatomic particle long predicted by theorists has finally been observed, ending a decades-long wait in physics. Named Ξcc+ ...

AT SOME point in our lives, most of us learn that atoms are comprised of three types of particle: neutrons, protons and electrons. Each has distinct properties. The electron and proton have opposite ...

The detector array consists of plastic scintillator detectors, quadrant silicon detectors (QSD), double-sided silicon detectors (DSSD) and high-purity germanium (HPGe) detectors. Exotic nuclei near ...

Physicists have begun to explore the proton as if it were a subatomic planet. Cutaway maps display newfound details of the particle’s interior. The proton’s core features pressures more intense than ...

Two thousand feet under the shores of Lake Erie, in a six-story salt cavern, one of the most sophisticated light detectors ever constructed is waiting. Every second, several particles speed through ...

Radioactive decay is a fundamental process in nature by which an unstable atomic nucleus loses energy by radiation. Studying nuclear decay modes is crucial for understanding properties of atomic ...

LHCb’s discovery of proton-like particles behaving differently than their antimatter counterparts brings scientists one step closer to finding out why antimatter disappeared in the early universe.

If you ask how much an object like a bicycle weighs, there’s a simple answer. But if you ask where the mass of a bicycle is, things get more complex. The bike has a lot of parts—some of which ...
