Individual protons and neutrons in atomic nuclei turn out not to behave according to the predictions made by existing theoretical models. This surprising conclusion, reached by an international team ...

The study is part of Henna Kokkonen's doctoral thesis. Credit: Tommi Sassi For the first time in almost 30 years, the heaviest nucleus decaying via proton emission has been measured. The previous ...

How many protons can dance on the head of a pin? The answer is nowhere near as straightforward as one may think — and it might offer new insights into one of the most well-tested theories in physics.

For surfers, it's not enough just to wait for the right wave: they still have to know how to catch it. As it turns out, one challenge faced by surfers also applies to protons. An experiment recently ...

For the first time, quarks and gluons were used to describe properties of atomic nuclei, which until now had been explained by the existence of protons and neutrons. The temporary pair of correlated ...

A new measurement of the strong nuclear force, which binds protons and neutrons together, confirms previous hints of an uncomfortable truth: We still don’t have a solid theoretical grasp of even the ...

We used to think we understood protons, but these bedrocks of the atomic nucleus could send our theories of particle physics tumbling IN THE long life of a proton, 10 years is a mere trice. These ...

According to the classical model of nuclear structure, the internal structure of nucleons should not change if they are bound into atomic nuclei. But it was discovered 35 years ago that quarks inside ...

Since the beginning of time, human beings have sought to understand what the universe and everything within it is made up of. And while ancient magi and philosophers conceived of a world composed of ...

For most of us, 4 percent off around the waist — a couple of belt notches — would be a great triumph. Not so for the proton, the subatomic particle that anchors atoms and is the building block of all ...
