First search for boosted Higgs boson production using the H->bb decay with CMS / Vernieri, Caterina (speaker) (Fermi National Accelerator Lab. (US))
An inclusive search for the standard model Higgs boson produced with high transverse momentum decaying to a bottom-antibottom quark pair has been performed using a data set of pp collisions at √s = 13 TeV collected with the CMS experiment at LHC. The data sample corresponds to an integrated luminosity of 35.9 fb−1. [...]

F-Theory - From Geometry to Physics and Back / Weigand, Timo (speaker) (CERN)
Compactifications of string theory have the potential to form a bridge between what we believe is a consistent quantum theory of gravity in 10 spacetime dimensions and observed physics in four dimensions. At the same time, beautiful results from mathematics, especially algebraic geometry, are directly linked to some of the key concepts in modern particle and quantum field theory. [...]

Less is more: regularization perspectives on large scale machine learning / Rosasco, Lorenzo (speaker) (MIT, IIT and University of Genova)
Modern data-sets are often huge, possibly high-dimensional, and require complex non-linear parameterization to be modeled accurately. Examples include image and audio classification but also data analysis problems in natural sciences, e..g high energy physics or biology. Deep learning based techniques provide a possible solution at the expanse of theoretical guidance and, especially, of computational requirements. It is then a key challenge for large scale machine learning to devise approaches guaranteed to be accurate and yet computationally efficient. [...]

Schroedinger’s Mirrors - exploring mechanical motion in the quantum regime / Aspelmeyer, Markus (speaker) (University of Vienna, Austria)
The quantum optical control of solid-state mechanical devices, quantum optomechanics, has emerged as a new frontier of light-matter interactions. Devices currently under investigation cover a mass range of more than 17 orders of magnitude - from nanomechanical waveguides of some picograms to macroscopic, kilogram-weight mirrors of gravitational wave detectors.

Lepton Flavour Universality tests using semitauonic decays at LHCb / Romero Vidal, Antonio (speaker) (University of Santiago de Compostela (ES))
Tests of Lepton Flavour Universality are a sensitive probe for physics beyond the Standard Model (SM). Experimental tests of this feature in semitauonic b-hadron decays, such as $B \to D^\ast\tau\nu$, are sensitive to new particles that preferentially couple to the third generation of leptons.  The world average for the ratios $\mathcal{B}(B \to D^{(\ast)}\tau\nu)\,/\,\mathcal{B}(B \to D^{(\ast)}\mu\nu)$ deviates from the very precise prediction of the SM by about 4 sigma, making this one of the most intriguing hints of potential new physics effects in the flavour sector. The latest results on the measurement of semitauonic decays at LHCb are  presented, along with future prospects..
