Video Library

Since 2002 Perimeter Institute has been recording seminars, conference talks, public outreach events such as talks from top scientists using video cameras installed in our lecture theatres.  Perimeter now has 7 formal presentation spaces for its many scientific conferences, seminars, workshops and educational outreach activities, all with advanced audio-visual technical capabilities. 

Recordings of events in these areas are all available and On-Demand from this Video Library and on Perimeter Institute Recorded Seminar Archive (PIRSA)PIRSA is a permanent, free, searchable, and citable archive of recorded seminars from relevant bodies in physics. This resource has been partially modelled after Cornell University's arXiv.org. 

Accessibly by anyone with internet, Perimeter aims to share the power and wonder of science with this free library.

The Standard Model Higgs boson may be mixed
with another scalar that does not couple singly to gauge bosons or fermions.
The electroweak quantum numbers of such an additional scalar can be determined
by measuring the quartic Higgs-Higgs-vector-vector couplings, which
contribute—along with the coveted triple Higgs coupling—to double Higgs
production in e+e− collisions. We show that simultaneous sensitivity
to the quartic Higgs-Higgs-vector-vector coupling and the triple Higgs coupling

An analytical understanding of large-scale matter
inhomogeneities is an important cornerstone of our cosmological model and helps
us interpreting current and future data. The standard approach, namely Eulerian
perturbation theory, is unsatisfactory for at least three reasons: there is no
clear expansion parameter since the density contrast is not small everywhere;
it does not consistently account for deviations at large scales from a perfect
pressureless fluid induced by short-scale non-linearities; for generic initial

Causal
Dynamical Triangulations” (CDT) is a lattice theory where aspects of quantum
gravity can be studied. Two-dimensional CDT can be solved analytically and the
continuum (quantum) Hamiltonian obtained.

In this talk I will show that this continuum Hamiltonian is the one obtained by
quantizing two-dimensional projectable Horava-Lifshitz gravity.

The majority of work on asymptotically anti-de Sitter
spacetimes, much of it motivated by the AdS/CFT correspondence, assumes
configurations which are either at or close to equilibrium.

The recent discovery
of the Higgs boson is a fundamental advance in particle physics. This talk
gives a theorist's perspective of the significance of this discovery. The Higgs
boson was proposed in the 1960s, but it is best understood in the context of
the quest to understand the weak interactions, which began with Fermi's theory
of weak interactions almost 80 years ago. This has led to three very different
paradigms for the structure of fundamental interactions at the TeV scale:
