The feebly-interacting massive particle (FIMP) paradigm offers an intriguing solution to the dark matter (DM) puzzle with FIMPs produced via the freeze-in mechanism due to extremely weak interactions with the standard model (SM) plasma.

Holographic description of the Nieh-Yan anomaly.

In 2 dimensions holographic duality gives the possibility of studying quantum gravity in terms of the dual SYK quantum mechanical theory. A particularly capturing model involves two coupled SYK systems.

What if dark matter only interacts with the visible sector through gravity?

The elements of the CKM matrix are fundamental parameters of the Standard Model. Substantial experimental and theory efforts are under way aimed at determining them ever more precisely and accurately.

Strong gravitational lensing is a powerful observational tool in astrophysics and cosmology which has been used to study the mass and light properties of galaxies and quasars the scales and distributions of dark matter subhaloes and the expansion history of the Universe.

In recent times quantum computational complexity has been a major interest to both QI and HEP communities. Complexity in the Krylov basis is one such candidate which has proved its worth in several setups by providing us with meaningful insights.

I will give a brief overview of the so called flavor anomalies, describing the main strategies followed to disclose physics beyond the Standard Model. I will focus on selected modes and observables that can help identifying the nature of new physics.

Cluster cosmology is potentially one of the most powerful observational probes of structure formation. However, enabling unbiased cosmological constraints requires careful modeling of the cluster selection function. In the case of optical cluster cosmology, this requires accurate modeling of projection effects. We will introduce a new simulation-based inference framework with which we reanalyze DES Y1 […]
