How long do fundamental particles live? In the Standard Model, we know particles can have many different lifetimes; from the top quark which decays in less than a millionth of a billionth of a billionth of a second, to stable particles like the…

The top quark is the heaviest particle in the standard model, and since its discovery in 1995 at the Tevatron collider at Fermilab, its study has become prominent in furthering our understanding of fundamental physics. At the Large Hadron Collider,…
