## String Theory

This is a collection of links to video lectures on string theory from CERN. String theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called strings.

Video/text | String theory for pedestrians |

Description | By Constantin Bachas, 2009. This is a non-technical rapid course on string theory. Lecture 1 is an introduction to the basics of the subject: classical and quantum strings, D-branes and string-string dualities. In lecture 2 I will discuss string unification of the fundamental forces, covering both its successes and failures. Finally in lecture 3 I will review string models of black hole microstates, the holographic gauge/gravity duality. ... |

Video/text | String theory for pedestrians |

Description | By B. Zwiebach, 2007. In this 3-lecture series I will discuss the basics of string theory, some physical applications, and the outlook for the future. I will begin with the main concepts of the classical theory and the application to the study of cosmic superstrings. Then I will turn to the quantum theory and discuss applications to the investigation of hadronic spectra ... |

Video/text | String theory |

Description | By C. Johnson, 2005. The primary emphasis of the lectures will be the study of non-perturbative regimes of string theory. The first lecture will be broad and at a general level, touching on a number of topics. The remaining lectures will be more detailed, exhibiting some key tools and phenomena which have formed the foundation for several recent advances in the field. ... |

Video/text | Physics of Extra Dimensions |

Description | By V. Rubakov, 2004. An overview of phenomenological models with extra spatial dimensions will be given, with emphasis on relatively recent (less than a decade old) ideas and results. Central focus will be on various versions of the "brane world" scenario, some of which suggest that extra dimensions may be accessible experimentally in foreseeable future, either at colliders or in searches for exotica. ... |

Video/text | Introduction to string theory |

Description | By W. Lerche, 2002. I will present a simple and non-technical overview of string theory, aimed for non-experts who like to get some idea what string theory is about. Besides introductory material, I intend to cover also some of the more recent developments. ... |

Video/text | An overview of string theory |

Description | By W. Lerche, 2000. One of the quests of particle physics is to formulate a single theory, which unifies particles and their interactions. String theory could be a candidate for this since some implementations not only generate Higgs and Gauge fields, but also imply gravitons. ... |
