Since the era of particle colliders, physicists claim to have discovered many different types of elementary particles and with the latest discovery of the Higgs boson in 2012 at the Large Hadron Collider (LHC) the standard model of particle physics is complete. The lifespan of such exotic particles however is in the order of 10^(-25) seconds which is a much smaller time interval humanity measured so far. What gives the physicists the right to claim they have discovered such particles? In this video, I am going to talk about how such particles are detected and what it truly means when physicists say they detected a new particle.
