The Mystery of Neutrino Mass

The standard model of particle physics is, perhaps ironically, written in the language of quantum field theory. Particles manifest as a consequence of the oscillatory motion of the associated fields. All known fermions, particles with half-integral spin such as the electron and the quarks, are massive particles. Fermion mass is a direct consequence of theContinue reading “The Mystery of Neutrino Mass”

Models of Nuclear Physics

The atomic nucleus is one of the most fascinating objects in the universe. Groups of protons and neutrons, themselves composed of quarks, bind together as a result of the strong nuclear force that, at distances of around 1fm = 1×10-15m, is potent enough to overcome proton-proton electromagnetic repulsion. The continuous tug of war between theseContinue reading “Models of Nuclear Physics”

Scattering: Unmasking Nature

Understanding the composition and structure of matter is perhaps the most ubiquitous objective across the physical sciences. The fundamental structures found within matter are typically on the nanometre scale and have thus proved unobservable for most of history. Following a number of developments during the 20th century, we are now capable of probing nature toContinue reading “Scattering: Unmasking Nature”

The Standard Model of Particle Physics: An Introduction

Developed in the early 1970s, the standard model is the reigning theory of particle physics, classifying all known elementary particles and describing 3 of the 4 fundamental forces of nature – namely the electromagnetic, weak and strong interactions – and how they interact. Fundamental Forces All forces observed in everyday life arise from one ofContinue reading “The Standard Model of Particle Physics: An Introduction”
