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 [...]

Exactly solvable irrelevant deformations and holography beyond AdS/CFT
/ Guica, Monica (speaker)
It is believed that gravity is holographic, namely that the gravitational dynamics in a given spacetime (region) can be encoded by a non-gravitational theory living on the boundary of that region. The AdS/CFT correspondence is an extremely successful concrete realization of the holographic idea; however, generalizing the holographic dictionary beyond AdS/CFT has proven to be difficult. [...]

High-precision measurement of the W boson mass at CMS
/ Bendavid, Josh (speaker) (Massachusetts Inst. of Technology (US))
The W boson mass is measured using proton-proton collision data at corresponding to an integrated luminosity of 16.8 inverse fb recorded during 2016 by the CMS experiment. The W boson mass is obtained from a fit of the two-dimensional pT-η distribution in a sample of W→μν decays, categorized by charge, yielding one of the most precise measurements of the W mass to date.

The Copernican Revolution, and how it almost became unnoticed and forgotten
/ Roszkowski, Leszek (speaker) (Astrocent at the Nicolaus Copernicus Astronomical Center of the Polish Academy of Sciences and National Centre for Nuclear Research, Poland)
The Copernican Revolution — the heliocentric model of the Universe introduced by Nicolaus Copernicus — is considered as one of the most significant achievements in the history of science. And yet, it luckily happened despite many obstacles and even then it could have become unnoticed and forgotten [...]

Update on reheating after inflation and its gravitational wave probes
/ Laine, Mikko Sakari (speaker) (Universitaet Bern (CH))
The reheating stage remains a strongly model-dependent and theoretically poorly understood part of the inflationary paradigm. However, the possibility that it could one day be tested via its gravitational wave signatures, and that it may also be related to other relicts such as dark matter or baryon asymmetry, continues to motivate studies with many models and methods. [...]
