The National Academies of Sciences, Engineering, and Medicine are private, nonprofit institutions that provide expert advice on some of the most pressing challenges facing the nation and world. Our ...

In particle physics, data long outlives the detectors that generate it. A decade ago the 4,100-metric-ton Collider Detector at Fermilab (CDF) reached the end of its life and was shut down, stripped of ...

Measurement of W boson particle mass confirms Standard Model of physics and reignites the search for other particles.

In three-dimensional particle physics, elementary particles divide nicely into fermions and bosons. But in lower-dimensions, things aren’t so clear cut. These dimensions host a “third kingdom” of ...

Nearly every object we interact with in our lives has a mass, but where does this mass come from? Modern physics says matter ...
