CERN Accelerating science

About Webcast Service
The CERN Webcast collection offers access to particle physics lectures and seminars. This service allows you to watch archived lectures at your convenience. Lectures that are planned to be recorded in the close future can also be found from this page. Currently, videos are streamed using mainly RealNetworks technology.

Non-invertible coset symmetry and fractionalization / Hsin, Po-Shen (speaker) (King's College London)
Coset symmetry arises in many systems such as Higgs phases of gauge theories and quantum spin liquids. When the coset is quotient by a non-normal subgroup, coset symmetry becomes a non-invertible symmetry. [...]

Open Strings, Instantons and Heterotic Vacua / Righi, Nicole (speaker) (King's College London)
Motivated by closed string perturbation theory arguments, I consider nonperturbative effects in the string coupling in supersymmetric critical heterotic string theories that are stronger than field theory ones. I will argue that in 10D, such effects arise from heterotic “D-instantons,” i.e. [...]

Probing the Standard Model to 0.37 ppm with the muon anomalous magnetic moment / Lellouch, Laurent (speaker) (CNRS & Aix-Marseille U.)
For the past fifty years, the Standard Model has been hugely successful in describing subatomic phenomena. However, recent measurements of the anomalous magnetic moment of the muon (a_mu) appear to challenge that statement, as they show a significant discrepancy with the reference Standard Model prediction. [...]

New measurement of the K+ -> pi+nunu decay by the NA62 Experiment / Swallow, Joel Christopher (speaker) (INFN - Laboratori Natzionali di Frascati)
The $K \to \pi \nu \bar\nu$ decay is a golden mode for flavour physics. Its branching ratio is predicted with high precision by the Standard Model to be less than $10^{-10}$, and this decay mode is highly sensitive to indirect effects of new physics up to the highest mass scales [...]
