Scale and Conformal Invariance in Higher Derivative Shift Symmetric Theories
Mahmoud Safari, Andreas Stergiou, Gian Paolo Vacca +1
The critical behavior of infinite families of shift symmetric interacting theories with higher derivative kinetic terms (non unitary) is considered. Single scalar theories with shi…
A different kind of four dimensional brane for string theory
Matteo Romoli, Omar Zanusso
We present a generalization of the string's Polyakov action that describes a conformally invariant four dimensional brane. The new extended object is very different from the tradit…
The search for the universality class of metric quantum gravity
Riccardo Martini, Alessandro Ugolotti, Omar Zanusso
On the basis of a limited number of reasonable axioms, we discuss the classification of all the possible universality classes of diffeomorphisms invariant metric theories of quantu…
Multicritical hypercubic models
Riccardo Ben Alì Zinati, Alessandro Codello, Omar Zanusso
We study renormalization group multicritical fixed points in the -expansion of scalar field theories characterized by the symmetry of the (hyper)cubic point group . After r…
Gravity in dimensions and realizations of the diffeomorphisms group
Riccardo Martini, Alessandro Ugolotti, Francesco Del Porro +1
We discuss two distinct realizations of the diffeomorphism group for metric gravity, which give rise to theories that are classically equivalent, but quantum mechanically distinct.…
