# Beyond the Standard Model for Montaneros

## TL;DR

This paper reviews various theories beyond the Standard Model, including alternative Higgs mechanisms, supersymmetry, grand unification, and extra dimensions, highlighting their theoretical foundations and phenomenological implications.

## Contribution

It provides a comprehensive overview of beyond Standard Model theories, integrating concepts from composite Higgs models to superstring theories.

## Key findings

- Electroweak symmetry breaking mechanisms
- Supersymmetry phenomenology
- Implications of extra dimensions

## Abstract

These notes cover (i) electroweak symmetry breaking in the Standard Model (SM) and the Higgs boson, (ii) alternatives to the SM Higgs boson including an introduction to composite Higgs models and Higgsless models that invoke extra dimensions, (iii) the theory and phenomenology of supersymmetry, and (iv) various further beyond topics, including Grand Unification, proton decay and neutrino masses, supergravity, superstrings and extra dimensions.
