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. Refreshments will be served at 10:30

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. [...]

Scattering Amplitudes: from Collider Physics to Geometry / Tancredi, Lorenzo (speaker) (Technische Universitat Munchen (DE))
In this talk I will review, in an introductory manner, the latest developments in the theory of scattering amplitudes and their connection to the geometrical properties of special classes of complex varieties. I will also discuss explicit examples of correlators and scattering amplitudes which can be related to elliptic geometries and beyond. [...]

Material for magnets & measurements II / Sgobba, Stefano (speaker) (CERN)
Magnetic materials, both hard and soft, are used extensively in several components of particle accelerators. Magnetically soft iron-nickel alloys are used as shields for the vacuum chambers of accelerator injection and extraction septa; Fe-based material is widely employed for cores of accelerator and experiment magnets. [...]

Powering infrastructures / Yammine, Samer (speaker) (CERN)
Power converters play a central role in particle accelerators where both their performances are directly linked. As accelerator complexes develop towards higher beam energies and a more sustainable nature, in response to the needs of physics research and of reducing the environmental impact, power converters are required to be on the forefront of technology.

Superferric magnets / Statera, Marco (speaker) (INFN Milano - LASA)
A brief introduction to the superferric magnets is given, what are they and why we use them. An overview of the use of superferric magnets in synchrotrons by selected examples from past to actual projects. A special focus is dedicated to HL-LHC high Orde Correctors with a  detailed description of the design and performance, highlighting the contribution of the superferric configuration. The potential contribution of superferric magnets for increasing sustainability of research infrastructure is finally discussed..
