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…
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…
