Protons sit in the nuclei of all atoms, but they are not fundamental particles: They are made of three quarks held together by the strong nuclear force. The strength of this interaction is actually ...

New research conducted by nuclear physicists is using a method that connects theories of gravitation to interactions among the smallest particles of matter. The result is insight into the strong force ...

Atomic nuclei exhibit multiple energy scales simultaneously—ranging from hundreds down to fractions of a megaelectronvolt. A new study demonstrates that these drastically different scales can be ...

We are getting closer to understanding when the strong nuclear force loosens its grip on the most basic constituents of matter, letting quarks and gluons inside particles abruptly turn into a hot ...

Despite dozens of experiments over the years, scientists still don't have a precise measurement for gravity's strength. Why is that?

The ATLAS collaboration recently measured the strength of the strong force to a record level of precision, but there’s still a long way to go toward understanding this fundamental force. In September, ...
