Journey through Gauge Theories: From Foundations to New Frontiers

From the humble beginnings of particle physics to groundbreaking discoveries, the journey of particle physics has revolutionized our understanding of the universe. The progression of particle physics, begin from the discovery of new particles, to gauge symmetries and many successful theories in its journey which help in building up the model that explain the underlying makeup of matter, regulated by fundamental forces led to establishment of Standard Model(SM). The discovery of neutrino oscillations compelled scientists to explore theories that extend beyond the Standard Model, which opened up new frontiers in the field of particle physics. The theories have shifted its paradigm to a single comprehensive theory at the scale of 10^14 GeV. This article explains the journey of particle physics from the basic constituent to the theory of everything.
