Course objectives

The course focuses on the study of cosmic particles and how their flux data is used to search for dark matter particles. Specifically, we will examine the origin and propagation of cosmic rays, gamma rays, and neutrinos within the Milky Way. Additionally, we will explore the primary and secondary Galactic and extragalactic sources of cosmic particles. The course will also provide an overview of WIMP (Weakly Interacting Massive Particle) models for dark matter, and we will discuss the methods and tools used in the search for these particles.

Program

a) Galactic cosmic rays (9 hr)

1. Brief introduction of cosmic radiation. Historical overview, cosmic ray composition, energy spectrum, detection strategy (1hr).
2. Cosmic-ray propagation. Introduction to Diffusion, convection, reacceleration, spallation, Energy losses (2hr).
3. Acceleration mechanisms and sources of Galactic cosmic rays (2hr).
4. Overview about current measurements of Galactic cosmic rays and possibile astrophysical interpretations (2hr).
5. Solving analytically or numerically the propagation equation (2hr).

b) Gamma ray and neutrino physics (5 hr)

1. Non thermal emission of photons from cosmic rays and Galactic sources (2hr).
2. Neutrino emission in the Galaxy and possible connection with the gamma ray flux (2hr).
3. Using gamma ray astronomy to study cosmic ray propagation (1hr).
4. Tools to study astroparticle with gamma-ray data (2hr).

c) Tools to study BSM models with direct detection, collider, indirect detection and relic density (6 hr)

1. Brief introduction about dark matter in the WIMP scenario (2hr).
2. Using Feynrules, Micromegas, MadDM and Pythia programs to have predictions for direct detection/relilc density/direct detection and collider (4hr).
