Nuclear and Particle Physics Proceedings, 2015 The cause of the screening of the weak interactions at long distances puzzled the high-energy community for more nearly half a century. With the discovery of the Higgs boson a new era started with direct experimental information on the physics behind the breaking of the electroweak symmetry.

Comptes Rendus. Physique, 2020 The existence of the Higgs boson was postulated more than 50 years ago, without any indication of its mass. The quest that followed, with several generations of particle physics experiments, culminated with the recent discovery of a new particle with a ...

The scale of new physics from the Higgs couplings to γγ and γZ
Journal of High Energy Physics, 2022 Measuring the Higgs couplings accurately at colliders is one of the best routes for finding physics Beyond the Standard Model (BSM). If the measured couplings deviate from the SM predictions, then this would give rise to energy-growing processes that ...

Higgs physics confronts the MW anomaly
Physics Letters B, 2022 The recent high-precision measurement of the W mass by the CDF collaboration is in sharp tension with the Standard Model prediction as obtained by the electroweak fit. If confirmed, this finding can only be explained in terms of new physics effects.

Steven Weinberg and Higgs physics
Nuclear Physics BAs a tribute to Steven Weinberg, we summarize the immense impact that he had on the understanding of the mechanism of spontaneous symmetry breaking and on the physics of the Higgs boson.

Deuteron uncertainties in the determination of proton PDFs
European Physical Journal C: Particles and Fields, 2021 We evaluate the uncertainties due to nuclear effects in global fits of proton parton distribution functions (PDFs) that utilise deep-inelastic scattering and Drell–Yan data on deuterium targets.

Quantum corrections to the primordial tensor spectrum: open EFTs & Markovian decoupling of UV modes
Journal of High Energy Physics, 2022 Perturbative quantum corrections to primordial power spectra are important for testing the robustness and the regime of validity of inflation as an effective field theory.

Pole-skipping of gravitational waves in the backgrounds of four-dimensional massive black holes
European Physical Journal C: Particles and Fields, 2023 Pole-skipping is a property of gravitational waves dictated by their behaviour at horizons of black holes. It stems from the inability to unambiguously impose ingoing boundary conditions at the horizon at an infinite discrete set of Fourier modes.

Classical Yang-Mills observables from amplitudes
Journal of High Energy Physics, 2020 The double copy suggests that the basis of the dynamics of general relativity is Yang-Mills theory. Motivated by the importance of the relativistic two-body problem, we study the classical dynamics of colour-charged particle scattering from the ...
