Particle and Astroparticle Physics

This book discusses group and field theories, summarizes the standard model of particle physics, and includes some extensions to the model, such as neutrino masses and CP violation. The book explores grand unified theories, supersymmetry, the general theory of relativity, higher dimensional theories of gravity, and superstring theory. It also introduces various novel ideas and models with extra dimensions and low-scale gravity. The last part of the book covers several specialized topics of astroparticle physics and cosmology, including baryogenesis, dark matter, dark energy, and brane cosmology.
