Flavourful Feebly-Interacting Particles (FIPs) in the MeV to GeV range have a strong impact on precision frontier observables ranging from rare meson decays to the lepton anomalous magnetic moments. Based on an effective field theory approach “SM+X” along with the HEPfit package to study the effect of FIPs on B to K observables. We present […]

By considering the photon-graviton scattering amplitude at low-energy including loops from the Standard Model, I will argue how we can infer constraints on the UV behaviour of the gravitational scattering amplitude. I will also comment on implications to other gauge fields in four and higher dimensions and application to the Weak Gravity Conjecture and connections […]

In this talk, I will give a description of semi-classical gravity in terms of quantum chaos and statistical physics. I will present the OPE Randomness Hypothesis (ORH), a generalization of ETH to CFTs which treats any OPE coefficient involving a heavy operator as a pseudo-random variable with an approximate Gaussian distribution. I will then present […]

In this talk, I will discuss various possibilities of producing dark matter in the early universe. By describing the transition between an inflationary epoch to a late time cosmology, I will emphasize how the dynamics of the universe can affect dark matter production and leave a cosmological imprint, allowing some of these scenarios to be constrained.

High-resolution spectroscopy of the simplest atoms and molecules plays an important role in the determination of fundamental physical constants such as the Rydberg constant or the proton charge radius, and may also be used to probe for hypothetical interactions beyond the standard model. As an introduction to this topic, I will review recent work on […]

Axion is a light particle arising in QCD as a solution to the strong CP problem and is considered to be one of the most promising dark matter candidate with interesting astrophysical and cosmological implications. At first, I will outline the scheme and sensitivity of a novel radio probe, axion gegenschein, in which axion-like particles […]

Within the AdS/CFT correspondence, the entanglement properties of the CFT are related to wormholes in the dual gravity theory. This gives rise to questions about the factorisation properties of the Hilbert spaces on both sides of the correspondence.  We review these issues and show how the Berry phase, a geometrical phase encoding information about topology, […]
