The neutrinoless double beta (0νββ) decay, if observed, has important implications on particle physics, cosmology and fundamental physics. In particular it can give access to the effective neutrino mass. [...]

Electronic contribution to the oscillations of a gravitational antenna / Branchina, Vincenzo (CERN ; Strasbourg, IReS) ; Gasparini, Alice (Geneva U.) ; Rissone, Anna (Geneva U.)
We carefully analyse the contribution to the oscillations of a metallic gravitational antenna due to the interaction between the electrons of the bar and the incoming gravitational wave. To this end, we first derive the total microscopic Hamiltonian of the wave-antenna system and then compute the contribution to the attenuation factor due to the electron-graviton interaction. [...]

The Price of an Exact, Gauge-Invariant RG-Flow Equation / Branchina, Vincenzo (CERN ; Strasbourg, IReS) ; Meissner, Krzysztof A. (Warsaw U.) ; Veneziano, Gabriele (CERN)
We combine old ideas about exact renormalization-group-flow (RGF) equations with the Vilkovisky-De Witt (VDW) approach to reparametrization invariant effective actions and arrive at a new, exact, gauge-invariant RGF equation. The price to be paid for such a result is that both the action and the RGF equation depend explicitly upon the base point (in field space) needed for the VDW construction. [...]

Effective action and the quantum equation of motion / Branchina, V (CERN) ; Faivre, H (ULP, Strasbourg, France ; CNRS, Strasbourg, France) ; Zappalà, D (INFN, Catania, Italy ; Univ. di Catania, Catania, Italy)
We carefully analyse the use of the effective action in dynamical problems, in particular the conditions under which the equation $\frac{\delta \Ga} {\delta \phi}=0$ can be used as a quantum equation of motion, and the relation between the asymptotic states involved in the definition of $\Ga$ and the initial state of the system. By considering the quantum mechanical example of a double-well potential, where we can get exact results for the time evolution of the system, we show that an approximation to the effective potential in the quantum equation of motion that correctly describes the dynamical evolution of the system is obtained with the help of the wilsonian RG equation (already at the lowest order of the derivative expansion), while the commonly used one-loop effective potential fails to reproduce the exact results..

A new, exact, gauge-invariant RG-flow equation / Branchina, Vincenzo (Strasbourg, IReS) ; Meissner, K A (Warsaw U.) ; Veneziano, Gabriele (CERN)
We introduce a scale-dependent effective action defined through a partial Legendre transform first discussed by Zumino more than 30 years ago. [...]
