Nuclear, Particle, Astroparticle and Cosmology (NUPAC) Seminars
On the interplay between Higgs physics, weak interactions, and gravitation
Presented by Roberto Onofrio (University of Padova and ITAMP, Harvard-Smithsonian Center for Astrophysics)
Quantum physics and gravitation have been considered for a long time as two non-overlapping theories, with prevalent domain of applicability in the micro and macroworld, respectively. Yet, in our search for a unified picture of Nature we need to find situations in which there is cross-talk between the quantum and gravitation, to highlight possible contradictions and ways to overcome them. I will show how atomic physics may help to smooth out this situation, discussing two examples related to macroscopic consequences of the Higgs field in astrophysics and gravitation [1,2,3], and microscopic consequences of a conjecture in which weak interactions may be interpreted as manifestations of gravity at the Fermi scale [4,5,6].
