Dr Simona Gallerani (Scuola Normale Superiore)25/10/2017, 14:25talkBlack holes are extreme singularities of the space-time that play a fundamental role in Astrophysics and Cosmology. In particular, black holes of the order of millions to billions solar masses (Super Massive Black Holes) are present in the cores of local galaxies as well as in the most distant Universe, shining as luminous quasars. Since the beginning of the new millennium, more than 100 of...Go to contribution page

Fiodor Sorrentino (INFN-Genova on behalf of the AEgIS collaboration)25/10/2017, 14:50The Weak Equivalence Principle (WEP) has been experimentally tested to high precision with differential gravity measurements using probes made of various “ordinary” matter. While in the WEP framework, antimatter should fall in the same way as matter, there is no direct evidence of this fact. A.E.g.I.S (Antimatter Experiment: Gravity, Interferometry, Spectroscopy), aims to test the WEP on...Go to contribution page

Prof. Andrew Koshelkin (National Research Nuclear University)25/10/2017, 15:15talkBy breaking the initial SU(N) symmetry, we derive the Lagrangian[1] governing the dynamics of the massive scalar particles, which can be treated as the octet of the pseudoscalar mesons. The contribution of both the quark-gluon interaction and self-interaction gluon field into the masses of the octet particles is considered. Provided that the hadronization of the confinement matter into...Go to contribution page

Dr Claudio Bonati (Dipartimento di Fisica, Universita' di Pisa)25/10/2017, 16:05In this talk I will discuss the connections between some nonperturbative features of the QCD vacuum and a possible dark matter candidate, the axion. While these relations are known since early '80s, only recently it was possible to start investigating these matters in a systematic way by using Lattice QCD simulations. I will discuss why these studies are particularly challenging from the...Go to contribution page

Caterina Braggio (PD)25/10/2017, 16:30talkThe properties of the QCD axion are described by several models that can be grouped into the KSVZ and DFSZ classes, depending on zero of full axion coupling to leptons, respectively. The axion-electron coupling, explicitly predicted by DFSZ models, has been considered to envisage the two types of haloscopes described in this talk. Due to their complementarity to conventional axion DM...Go to contribution page

Clemente Giuseppe (University of Pisa and INFN)25/10/2017, 16:55Causal Dynamical Triangulations is one of the present promising numerical approaches to the problem of Quantum Gravity. Motivated by the current lack of observables encoding geometric features at all scales, I will present a new set of observables based upon the analysis of eigenvalues and eigenvectors of the Laplace-Beltrami operator of triangulations, and discuss the main results obtained...Go to contribution page

Ms Pavlina Jaluvkova (JINR Dubna, Russia)25/10/2017, 17:20talkIn spite of the numerous attempts to close the discussion about the influence of cosmological expansion on local gravitationally bounded systems, this question arises in literature again and again and remains still far from its final resolution. Here one of the main problems is the problem of obtaining a physically adequate model of strongly gravitating object immersed in non-static...Go to contribution page
