Uncovering novel phase structures in scalar theories with the renormalization group
Mahmoud Safari, Gian Paolo Vacca
We present a detailed version of our recent work on the renormalization group approach to multicritical scalar theories with higher derivative kinetic term of the form $ϕ(-\Box)^kϕ…
Multi-critical scalar theories: A perturbative RG approach with -expansion
Mahmoud Safari, Gian Paolo Vacca
We employ perturbative RG and -expansion to study multi-critical single-scalar field theories with higher derivative kinetic terms of the form . We focus on those w…
New universality class in three dimensions: The critical Blume-Capel model
Alessandro Codello, Mahmoud Safari, Gian Paolo Vacca +1
We study the Blume-Capel universality class in dimensions. The RG flow is extracted by looking at poles in fractional dimension of three loop diagrams using $\ov…
Functional perturbative RG and CFT data in the -expansion
Alessandro Codello, Mahmoud Safari, Gian Paolo Vacca +1
We show how the use of standard perturbative RG in dimensional regularization allows for a renormalization group based computation of both the spectrum and a family of coefficients…
Leading CFT constraints on multi-critical models in d>2
Alessandro Codello, Mahmoud Safari, Gian Paolo Vacca +1
We consider the family of renormalizable scalar QFTs with self-interacting potentials of highest monomial below their upper critical dimensions , and st…
