The purpose of this workshop is to bring together scientists with different backgrounds and expertise to discuss open problems, recent developments and future directions in axion physics, a field that is notoriously replete with interdisciplinary connections. The aim is to foster a fruitful cross breeding between different theoretical areas, with a focus on certain open issues in axion particle physics, astrophysics and cosmology. Quantitative assessments of the axion contribution to Cold Dark Matter (CDM) involve top-notch lattice simulations of non- perturbative QCD effects, as well as of the cosmic evolution of axionic topological defects. Astrophysical observations provide strong bounds on axion properties because stellar evolution would be affected by the existence of axions and, intriguingly, some excesses in star energy losses have been reported. Cosmological scenarios in which the PQ symmetry is broken before inflation foresee axions imprints in the CMB, while in post-inflationary scenarios axion miniclusters, with overdensities several orders of magnitude larger than the local density of CDM, are expected to form, and a reliable assessment of their properties is of utmost importance. From the experimental side, a blossoming of potentially game-changing ideas, with an exciting crossover from experimental particle physics to materials science and cutting-edge technologies is inspiring new methods for axion searches. Novel techniques have been put forth that, besides exploiting the axion- photon coupling, aim to reveal axions via their couplings to nucleons and electrons. The interaction between the experimental and theoretical communities will foster the merging of `how to search’ with `where to search’ into optimized strategies to hunt for the axion.

The conference is hosted by the Istituto Nazionale di Fisica Nucleare, Sezione di Catania e Sezione di Milano in collaboration with the Milano University and the Dipartimento di Fisica e Astronomia "Ettore Majorana" of Catania University. The COMEX conferences are a continuation of the long series of topical conferences on giant resonances started in 1979.

This workshop will be co-organized by two main institutions, namely the University of Naples Federico II and the University of Durham.

This workshop aims to discuss the phenomenological implications of Primordial Black Holes (PBH), such as their possible relationship with dark matter origin, neutrino mass, the baryon asymmetry, inflation, their theoretical aspects and origin and the possible multi-messenger detection and the experimental state-of-the-art. Recently, the interest in PBHs from the physics community is growing because they can provide an alternative explanation of some of the major problems of the Standard Model. We know that Black Holes can merge or evaporate (according to the seminal paper by Hawking), generating gravitational waves, fluxes of Dark Matter, and standard model particles. Therefore, different experimental indirect searches can possible exploit the multi-messenger approach.

The goal of this meeting is to discuss and consolidate recent advances in the vibrant research fields of string theory, holography, black hole physics, and cosmology. We will address important open problems through an active program of talks by well recognized scientific leaders in the field. In addition, we will organize an open discussion forum for researchers with close ties to the countries from the Balkan region and other parts of Eastern Europe in which we plan to brainstorm about future activities of the existing SEENET-MTP network, and other networking collaborations that will enhance the development of fundamental theoretical physics in these countries.

Quantum field theory is not only the unifying language of fundamental forces, but also an extremely rich source of surprising non-perturbative dualities. This success in predicting unexpected new links among seemingly distant subjects has accelerated on many fronts over the past few years, thanks to applications of modern developments in “quantum” mathematics to quantum field theories with supersymmetric, integrable, conformal, topological, or holomorphic structures. The insights emerging from these developments have been the source of important novel results across various branches of theoretical physics and mathematics, hinting at further new connections awaiting discovery. The common ground to all these recent developments is the richness of the physics and mathematics underlying the dynamics of protected (BPS) sectors, whose study ties together fundamental questions in diverse fields in original ways. This workshop aims to highlight and discuss the impact of key developments, to forge new synergies, and to grasp together the hints of far-reaching new opportunities.
