Our Particle Universe
Quarks, nucleons, colour charge, gluons, neutrinos, pions, mesons, Higgs boson, Yukawa interactions, leptonic CP asymmetry, dark matter.
Ever since the discovery of the electron more than 100 yearsago, scientists have asked the questions –“what is our universemade of?” and “why is the universe the way it is?” Notlong before, it was found that these two questions are relatedto each other. The interactions of particles in the universedetermines its evolution, its very form, and existence. In thisarticle, we will trace the discovery of some of these particles,learn about their interactions, and try to understand theirproperties such as electric charge and mass.
