Increasing evidence for a stochastic gravitational background is being collected at pulsar timing arrays. The most plausible origin of the signal is the cumulative strain from the mergers of supermassive black holes at the center of galaxies across …
Recently there has been a growing interest in the measurements of quantum properties with collider experiments, and the ATLAS collaboration has reported the first observation of entanglement of top-antitop pairs last year (Nov. 2023). In this talk, I …
The baryon assymmetry of the universe gives indications for a First Order Electroweak Phase Transistion (FOEWPT) in the early universe. This in turn requires an extended Higgs sector with modifications of the triple Higgs couplings (THCs) with …
Gravitational waves are a unique probe of the early Universe, as the Universe is transparent to gravitational radiation right back to the beginning. Here, I will summarise some of the different scopes of primordial events that could lead to a …
Hidden sectors featuring confining gauge theories, commonly called hidden valleys, are a highly motivated possibility for new physics. They are plausible from a bottom-up point of view, can explain the origin or signals of dark matter and other …
Axions and axion-like particles couple to photons through a distinctive two-photon vertex. This vertex allows for axion decay into two photons. In this talk, I will show how we can search for axion dark matter by looking for excess radiation …
With the milestone discovery of the Higgs boson at the LHC, high energy physics has entered a new era. The completion of the "Standard Model" (SM) implies that we have a relativistic, quantum-mechanical, self-consistent theoretical framework, …
Neutrino-nucleus scatterings in the detector could induce electron ionization signatures due to the Migdal effect. We derive prospects for a future detection of the Migdal effect via coherent elastic solar neutrino-nucleus scatterings in liquid xenon …
We will discuss the possibility that dark matter is composed of sufficiently light particles that it effectively behaves as a collection of waves. We will review the particle physics motivations and the rich wave phenomenology, and discuss the …
As the LHC physics program continues, the search for physics beyond the Standard Model is now pushing into ever more challenging regimes: in particular, into final states that are low mass, long lifetime, and/or high multiplicity. Confining hidden …
