The first edition of Cosmoparticle Physics was published in 1999 and the successive development of cosmology and particle physics have proved the basic principles of cosmoparticle physics as the specific field, studying fundamental relationship of cosmology and particle physics.The second edition updates and extends the text to discuss about the latest developments, including the development of precision cosmology that lead to now standard ?CDM cosmological scenario, creation of gravitational wave astronomy, controversial results of direct and indirect dark matter searches, as well as absence of positive results of searches for supersymmetric particles at the LHC together with problems of Weakly Interacting Massive Particle paradigm.
