Scientists announced on Wednesday that they have found no evidence for the hypothetical “sterile neutrino,” an extra version of the ghostly neutrino particles that are ubiquitous in the universe. The ...

Theoretical particle physics is the development of models for describing fundamental particles and their interactions. This includes testing and refining the prevailing theory: the standard model.

CERN’s Super Proton Synchrotron will turn 50 in 2026—and it has a resonant “ghost.” Using mathematics, physicists measured and modeled how these resonant lines intersect. Modeling a 3D shape over time ...

Experimental particle physics is the practical investigation of the fundamental components of matter and radiation. A crucial tool in the arsenal of the experimental particle physicist is the particle ...
