The lectures are primarily addressed to Ph.D. students in High Energy Particle and Astroparticle Physics. The aim of the school is to give a pedagogical introduction to the basic concepts and tools needed for research, covering the foundations of the subject at a deep and advanced level. The main topics include the Standard Model of Particle Physics and its extensions, Collider Physics, Quantum Field Theory and Cosmology.

The origin of cosmic magnetism is one of the most fascinating topics in astrophysics and cosmology. Both a primordial or an astrophysical origin are consistent with current observations, which include upper limits on primordial magnetic seeds from the cosmic microwave background (CMB), detection of magnetic fields in large scales structures, and lower limits on the magnetisation of voids inferred by TeV blazars observations (difficult to explain by fully astrophysical seed magnetic fields). This new (hybrid) conference comprises different technical and theoretical expertises in a unique way.

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.

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.
