A short review on modular flavor symmetries

It has recently been demonstrated that the modular symmetry offers an elegant solution to the longstanding flavor mixing puzzle This innovative approach considers neutrino masses as modular forms, dependent on a complex modulus parameter. In this talk, I will briefly review recent developments in modular flavor symmetries, including their theoretical motivations, the basic knowledge about modular transformations, the generic methodology to construct a modular-invariant flavor model, and the distinctions between modular flavor symmetries and traditional flavor symmetries. In addition, I will also talk about the modulus stabilization.

Title:

Isotope shift spectroscopy

The search for "new" particles is dominated by the quest for dark matter candidates, but there are also motivations to search for yet undiscovered particles not related to dark matter. In particular, a growing community is searching for a hypothetical New Boson that would couple neutrons and electrons. Such an interaction would show up as an additional contribution to the binding energy of an electron in an atom, and can be accessed directly through the isotope shift of carefully chosen optical transitions. While this field of research has flourished in the past few years, it seems that we are re-discovering nuclear physics rather than new particles. I will give an overview on the current status of the field, particularly on the elements calcium, zinc, and mercury.
