Ten years ago, scientists announced the discovery of the Higgs boson, which helps explain why elementary particles (the smallest building blocks of nature) have mass.

For particle physicists, this was the end of a decades-long and hugely difficult journey – and arguably the most important result in the history of the field. But this end also marked the beginning of a new era of experimental physics.

In the past decade, measurements of the properties of the Higgs boson have confirmed the predictions of the standard model of particle physics (our best theory for particles). But it has also raised questions about the limitations of this model, such as whether there’s a more fundamental theory of nature.

Dr Martin Bauer and Dr Stephen Jones from our Institute for Particle Physics Phenomenology look back at the discovery of the Higgs boson, and discuss some of the questions still being explored by physicists 10 years in this article.
