We propose a novel solution to the strong CP problem based on modular invariance. The latter is inherent to toroidal compactifications in string theory. We show that modular invariance allows for simple effective theories of flavour and CP where (i) the QCD angle vanishes, (ii) the CKM phase is large, (iii) quark and lepton masses and mixings can be reproduced up to order one coefficients....

For decades, neutrinos have been used as astrophysical messengers, revealing new insights into some of the most interesting places in the Universe. In this talk, we discuss some recent developments in this field, concerning in particular neutrinos from neutron stars and from supernovae. In the latter context, we highlight in particular some recent results on quantum simulations of collective...

In this talk, I will present an overview of light primordial black hole (PBHs) phenomenology. I will first motivate why light PBHs are of particular interest to probe the evolution of the early universe. I will then review the many imprints that evaporating PBHs can leave in cosmological observatories and experimental particle physics experiments. I will finally end by elaborating on an...

I will review recent observations and analyses aimed at determining the mass of the Milky Way and the distribution of dark matter within it. I will also discuss how these determinations — and the uncertainties associated with them — impact the search for new physics in selected dark matter scenarios.

The field of pulsar timing array (PTA) searches for gravitational waves (GWs) is currently in an exciting phase, with the 5σ detection of a nanohertz GW background (GWB) possibly just around the corner. In this talk, I will review the current status of these searches and discuss possible beyond-the-Standard Model (BSM) sources of a GWB signal in the PTA frequency band. Finally, I will...

The cosmological constant problem remains one of the deepest puzzles in effective field theory and cosmology. In this talk, I will show how four-form field strengths offer model builders a valuable tool to tackle this challenge. I begin by reframing the problem using the infinite-wavelength (spacetime-averaged) trace of the gravitational equations. I then review and explore two main...

Symmetry is a powerful organizing principle. In this talk we review how symmetry can act on extended dynamical defects and constrain their IR dynamics. As applications, we will show how certain realizations of symmetries forbid IR trivial (screened) defects and how bulk 't Hooft anomalies induce interesting non-perturbative observables for symmetry-breaking defects.

Particle physics phenomenology in string theory is determined by topological and geometrical features of string compactifications. In this talk, I will discuss recent work using machine learning methods to compute these features, with a focus on the computation of Ricci-flat metrics of Calabi-Yau manifolds.

In recent years we have learned that several four-dimensional field theories can manifest non-invertible zero-form symmetries generalizing the Kramers-Wannier duality defect of the 2d critical Ising model. Several recent works by various groups have observed a deep interplay among such non-invertible symmetries in 3+1 dimensions, their anomalies, and the properties of the ground state(s). In...

I'll summarize the status of high-energy neutrino physics, including the role that IceCube and other telescopes play in the domains of astrophysics (cosmic ray acceleration, sources) and fundamental physics (neutrino oscillation parameters, dark matter searches, and other probes of physics beyond the Standard Model).

In this talk, I will explore the physics potential of coherent elastic neutrino-nucleus scattering (CEvNS), a neutral-current process in which a neutrino coherently scatters off an entire nucleus. I will begin by reviewing the key features of CEvNS and summarizing the current experimental landscape, including results from spallation neutron sources, reactor neutrino experiments, and dark...

We have long celebrated the great success of cosmology in predicting the observed properties of the cosmic microwave background. And yet, for well over two decades there has been consistent and slowly mounting evidence that on large scales the CMB is anomalous. The evidence is consistent from experiment to experiment and it implies the violation of statistical isotropy. I will discuss...

In the era of precision cosmology, persistent discrepancies between independent measurements — most notably the Hubble tension — have intensified, signaling potential cracks in the ΛCDM paradigm. In this talk, I will review the current status of the Hubble tension, and present well-motivated extensions to ΛCDM that can naturally reconcile the data.
