Abstract: A remarkable feature of the Standard Model (SM) is that each lepton flavour (electron, muon, tau) is equally likely to interact with a W boson. This is known as Lepton Flavour Universality. In a recent ATLAS measurement, a novel technique …
ABSTRACT: It is now well established that the dominant part of non-relativistic matter in the Universe is some substance which appears to be oblivious to any force but gravity. The nature of this dark matter remains a nagging puzzle, and several …

Abstract: The standard model of cosmology is built upon on a series of propositions on how the early, intermediate, and late epochs of the Universe behave. In particular, it predicts that dark energy and dark matter currently pervades the cosmos. …
Abstract: This seminar presents the search for the rare Higgs boson decay to a pair of muons performed by the CMS experiment at the LHC, based on the full Run 2 dataset. Events are categorized based on the characteristics of …
ABSTRACT Clustering of matter on large scales provides an important source of information on key cosmological parameters. To extract this information we need to understand the relation between the tracers we observe and the underlying matter field. The clustering strength …
Abstract: The Snowmass process is an opportunity for the entire HEP community to come together to identify and document a vision for the future of particle physics in the U.S. and its international partners. The Snowmass 2021 process is currently …
Hannsjörg Weber Triple Threat: The observation of tribosons Abstract: We present the search for heavy triboson production, specifically targeting the production of WWW, WWZ, WZZ and ZZZ processes in multileptonic final states with 137/fb of data collected by the CMS …

Abstract: Muon colliders represent a highly attractive option for future collider thanks to the possibility to reach very high center of mass energy, high luminosity with reasonable costs and dimensions. Nevertheless, the feasibility is not yet fully demonstrated and presents …

ABSTRACT: In this talk, I explain how various concepts and techniques in quantum field theory and collider physics can be naturally translated into a new geometric language. Using the energy mover's distance, which quantifies the minimal amount of "work" required …

Abstract: Measurements of the universe's present-day expansion rate, or the Hubble constant (H0), that use a Cepheid variable star calibration of Type Ia supernovae (SNe Ia) are in >4σ disagreement with values predicted by the standard, Lambda cold dark matter …
