Proton–proton collisions at the LHC produce a large number of particles that are emitted very close to each other, at distances of about 10-15 m (a femtometer). It is interesting to explore ...

An interesting thing happened to me on the way to writing this column. Last week I wrote: “It’s fun to know a few things that are not all that important.” ...

Particle physics is the study of the elementary building blocks of matter and radiation and their interaction. The fundamental particles are summarised by the standard model. This includes leptons ...

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 ...
