Physics Beyond the Standard Model

TL;DR

This paper discusses open questions in the Standard Model related to mass, forces, and matter, exploring speculative theories like supersymmetry, grand unification, and superstrings to address these fundamental issues.

Contribution

It provides an overview of theoretical ideas beyond the Standard Model, highlighting recent developments and speculative models aiming to explain fundamental particles and forces.

Findings

Explores supersymmetry and its implications.

Discusses grand unified theories and superstrings.

Highlights open questions and future directions in fundamental physics.

Abstract

In these lectures I describe some of the open questions in the standard model relating to the nature and origin of mass, forces and matter and discuss some of the speculative theoretical ideas put forth in this regard. Some of the topics touched upon include supsersymmetry, dynamical symmetry breaking, composite models, grand unified theories and superstrings.
