High-energy behavior of scattering amplitudes in theories with purely virtual particles
Marco Piva
We study a class of renormalizable quantum field theories with purely virtual particles that exhibits nonrenormalizable behavior in the high-energy limit of scattering cross sectio…

Renormalization of Massive Rank-1 Field Theory Nonminimally Coupled to Quantum Gravity
Marco Piva
We consider a self-interacting, massive rank-1 field coupled to quantum gravity. The theory is renormalizable by power counting and contains a massive spin-1 field and a massive sc…

Higher-Derivative Quantum Gravity with Purely Virtual Particles: Renormalizability and Unitarity
Marco Piva
We review the formulation of quantum field theories with purely virtual particles, a new type of degrees of freedom that can mediate interactions without ever appear as external on…
