The Standard Model of Particle Physics

This is a collection of links to video lectures related to the Standard Model of particle physics from CERN - a theory concerning the electromagnetic, weak, and strong nuclear interactions.


Video/text Theories of Electroweak Symmetry Breaking
Description By James Daniel Wells, 2015. The goal of this lecture is to put the discovery of the Higgs boson in historical context and qualitatively discuss the importance and meaning of its discovery. Claims that the BEH theory has its roots in the theory developments of superconductivity will be considered. Viability of the theory from several points of view will be assessed. First, has the theory been established yet as correct? Second, is the theory stable to vacuum fluctuations? And finally, is the theory natural?

Video/text The Higgs Particle
Description By Marumi Kado, 2013. The recent discovery of a Higgs boson is a milestone in a half century long strive to unravel the origins of electroweak symmetry breaking. In the successful first three years of LHC operations at the energy frontier, the quest of Higgs bosons went from the era of searches, to the discovery and more recently on to the era of measurements of its properties. An overview of the these three phases, the implications of the discovery and future prospects will be discussed.

Video/text Electroweak Symmetry Breaking
Description By Roberto Contino, 2012. The focus of the lectures will be on the role of the Higgs boson in the mechanism of electroweak symmetry breaking, both in the Standard Model and in models of New Physics. In particular, I will discuss how a determination of its couplings to matter and gauge fields can give important information on the nature and origin of the Higgs boson. ...

Video/text An Introduction to Standard Theory of Electroweak Interactions
Description By Giovanni Ridolfi, 2011. The construction and experimental foundations of the unified theory of weak and electromagnetic interactions will be reviewed. Special attention will be given to the Standard Model symmetry properties and how symmetries must be broken in order to obtain a realistic theory for the observed pattern of masses and mixing among generations and to accommodate longitudinal degrees of freedom for the vector bosons. ...

Video/text Higgs Boson Searches at Hadron Colliders
Description By Karl Jakobs, 2010. The phenomenology of Higgs bosons and search strategies at hadron colliders are discussed. After a brief introduction on Higgs bosons in the Standard Model and a discussion of present direct and indirect constraints on its mass the status of the theoretical cross section calculations for Higgs boson production at hadron colliders is reviewed. ...

Video/text Electroweak symmetry breaking: to Higgs or not to Higgs
Description By Christophe Grojean, 2009. The aim of these lectures is, after briefly introducing SM physics and the conventional Higgs mechanism, to give a survey of recent attempts to go beyond a simple elementary Higgs. In particular, I will describe composite models (where the Higgs boson emerges from a strongly-interacting sector) and Higgsless models. ...

Video/text The Hunt for the Higgs particle
Description By Zwirner Fabio, 2007. These three lectures will review: the Higgs mechanism; its implementation in the minimal Standard Model; possible alternatives with and without elementary scalar fields; the presently available information on electroweak gauge symmetry breaking and the Higgs particle; the properties of the Higgs boson(s) in the Standard Model and its supersymmetric extensions. ...

Video/text Electroweak Theory and the Standard Model
Description By R. Barbieri, 2004. There is a natural splitting in four sectors of the theory of the ElectroWeak (EW) Interactions, at pretty different levels of development/test. Accordingly, the 5 lectures are organized as follows, with an eye to the future: Lecture 1: The basic structure of the theory; Lecture 2: The gauge sector; Lecture 3: The flavor sector; Lecture 4: The neutrino sector; Lecture 5: The EW symmetry breaking sector. ...

Video Physics beyond the Standard Model
Description By L. Ibanez, 2004. I discuss several issues beyond the standard model physics. Topics include, among others, grand unification, supersymmetry, models of extra dimensions and string models. ...

Video Beyond the Standard Model
Description By G. Giudice, 2000. After a critical discussion of the questions left unanswered by the Standard Model, I will review the main attempts to construct new theories. In particular, I will discuss grand unification, supersymmetry, technicolour, and theories with extra dimensions. ...

Video Introduction to the Standard Model
Description By G. Ridolfi, 2000. The construction of the standard gauge theory of weak and electromagnetic interactions (the Standard Model) will be described in detail, starting from phenomenological evidences and theoretical prejudices. Special attention will be devoted to the internal consistency of the theory (gauge invariance and anomaly cancellation). ...

Video Standard Model Physics
Description By G. Altarelli, 1999. Introduction structure of gauge theories. The QED and QCD examples. Chiral theories. The electroweak theory. Spontaneous symmetry breaking. The Higgs mechanism Gauge boson and fermion masses. Yukawa coupling. Charges current couplings. The Cabibo-Kobayashi-Maskawa matrix and CP violation. Neutral current couplings. ...

Video Introduction to physics beyond the Standard Model
Description By G. Giudice, 1998. These lectures will give an introductory review of the main ideas behind the attempts to extend the standard-model description of elementary particle interactions. After analysing the conceptual motivations that lead us to believe in the existence of an underlying fundamental theory, we will discuss the present status of various theoretical constructs : grand unification, supersymmetry and technicolour. ...

Video Beyond the Standard Model
Description By Antonio Masiero, 1997. A critical reappraisal of the Standard Model (SM) will force us to new physics beyond it. I will argue that we have good reasons to believe that the latter is likely to lie close to the electroweak scale. After discussing the possibility that such new physics may be linked to a dynamical breaking of SU(2)xU(1) (technicolour), I will come to the core of the course: low energy supersymmetry. ...
