## Particle Physics 2: Standard Model

**Particle Physics 2: Standard Model (Winter 2010, Stanford Univ.)**. Instructor: Professor Leonard Susskind. In this series Professor Susskind continues
his particle physics theme, focusing on the foundations of the Standard Model, which describes the interactions and properties of the observed particles.
These lectures cover the basics of group theory, symmetry, symmetry breaking, which are the natural way to describe the known particles. Several lectures are devoted to
the way that particles get their mass, popularly known as the Higgs mechanism.

Lecture 01 - Particles fields and forcesLeonard Susskind introduces theoretical concepts underlying the standard model. He also gives a zoological overview of the observed particles. |

Lecture 02 - Quantum chromodynamicsBasic concepts of quantum chromodynamics, The mathematics of spin, Isospin, Color, quarks, and gluons. |

Lecture 03 - Group theory - part 1Basic concepts of group theory, Groups and symmetries, Group representations, Group generators, Spin, Rotation groups, Color. |

Lecture 04 - Group theory - part 2This lecture continues developing group theory, making connections from group generators and subgroups to particles. Gluons properties are explored with this framework, including confinement of quarks. |

Lecture 05 - Gauge fields and symmetryThe concept of a gauge field and it's associated symmetries. Symmetries lead to conserved charges like the electric charge and color. These concepts are used to describe the weak interaction. |

Lecture 06 - The weak interactionThe weak interaction - Why is the weak force weak? Propagators, Explicit and spontaneous symmetry breaking. |

Lecture 07 - Spontaneous symmetry breaking and Goldstone bosonsThis lecture shows how spontaneous symmetry breaking in a field theory can lead to the creation of Goldstone bosons like the photon and gluons. |

Lecture 08 - The Higgs fieldLeonard Susskind explains the Higgs phenomena by discussing how spontaneous symmetry breaking induces a mass for the photon. |

Lecture 09 - The Higgs field and fermionsProfessor Susskind continues his description of the Higgs mechanism focusing on giving mass to fermions. |

Lecture 10 - Renormalization and the running of coupling constantsRenormalization, The mass of fermions, The W boson and mass scale for Higgs boson, The running of coupling constants and unification, Gravity at short distances. |
