Ising exponents from the functional renormalisation group
Daniel F. Litim, Dario Zappalá
We study the 3d Ising universality class using the functional renormalisation group. With the help of background fields and a derivative expansion up to fourth order we compute the…
An alternative heavy Higgs mass limit
P. Castorina, M. Consoli, D. Zappalá
After commenting on the present value of the Higgs particle mass from radiative corrections, we explore the phenomenological implications of an alternative, non-perturbative renorm…
Energetic model of tumor growth
Paolo Castorina, Dario Zappalá
A macroscopic model of the tumor Gompertzian growth is proposed. This approach is based on the energetic balance among the different cell activities, described by methods of statis…
Chiral symmetry breaking in the Wegner-Houghton approach
A. Bonanno, D. Zappala'
The Wegner-Houghton formulation of the exact renormalization group evolution equation is used in order to study the chiral symmetry breaking of the linear sigma model coupled to an…
Non-perturbative renormalization group approach for a scalar theory in higher-derivative gravity
Alfio Bonanno, Dario Zappalá
A renormalization group study of a scalar theory coupled to gravity through a general functional dependence on the Ricci scalar in the action is discussed. A set of non-perturbativ…
Renormalization Group Analysis of the Heavy Field Decoupling in a Scalar Theory
A. Bonanno, J. Polonyi, D. Zappalá
The problem of two coupled scalar fields, one with mass much lighter than the other is analysed by means of Wilson's renormalization group approach. Coupled equations for the poten…
