Renormalization group analysis of reggeon field theory: flow equations
J. Bartels, C. Contreras, G. P. Vacca
Can large distance high energy QCD be described by Reggeon Field Theory as an effective emergent theory? We start to investigate the issue employing functional renormalisation grou…
Are there scaling solutions in the O(N)-models for large N in d>4?
R. Percacci, G. P. Vacca
There have been some speculations about the existence of critical unitary O(N)-invariant scalar field theories in dimensions 4<d<6 and for large N. Using the functional renormaliza…
Asymptotic Safety in Einstein Gravity and Scalar-Fermion Matter
G. P. Vacca, O. Zanusso
Within the functional renormalization group approach we study the effective QFT of Einstein gravity and one self-interacting scalar coupled to N_f Dirac fermions. We include in our…
Stochastic growth of quantum fluctuations during slow-roll inflation
F. Finelli, G. Marozzi, A. A. Starobinsky +2
We compute the growth of the mean square of quantum fluctuations of test fields with small effective mass during a slowly changing, nearly de Sitter stage which took place in diffe…
