چکیده
A bstract general analysis of line defect renormalisation group (RG) flows in the ε expansion below d = 4 dimensions is undertaken. The beta function for scalar-fermion bulk theories computed to next-to-leading order couplings. Scalar models as well with various global symmetries are considered at leading non-trivial order. Different types potential infrared (IR) conformal field (dCFTs) and their RG stability discussed. possibility multiple IR stable dCFTs realised specific examples hypertetrahedral symmetry bulk. one-point coefficient parameter dCFT cubic model compared that Heisenberg model.

Counting RG flows
Interpreting renormalization group flows as solitons interpolating between different fixed points, we ask various questions that are normally asked in soliton physics but not in renormalization theory. Can one count RG flows? Are there different “topological sectors” for RG flows? What is the moduli space of an RG flow, and how does it compare to familiar moduli spaces of (supersymmetric) dowai...
متن کاملRG flows and bifurcations
Interpreting RG flows as dynamical systems in the space of couplings we produce a variety of constraints, global (topological) as well as local. These constraints, in turn, rule out some of the proposed RG flows and also predict new phases and fixed points, surprisingly, even in familiar theories such as O(N) model, QED3, or QCD4. © 2017 Published by Elsevier B.V.

متن کامل“integrability” of Rg Flows and Duality in Three Dimensions in the 1/n Expansion
I study some classes of RG flows in three dimensions that are classically conformal and have manifest g → 1/g dualities. The RG flow interpolates between known (four-fermion, WilsonFischer, φ3) and new interacting fixed points. These models have two remarkable properties: i) the RG flow can be integrated for arbitrarily large values of the couplings g at each order of the 1/N expansion; ii) the...
متن کاملComments on cosmological RG flows
We study cosmological backgrounds from the point of vue of the dS/CFT correspondence and its renormalization group flow extension. We focus on the case where gravity is coupled to a single scalar with a potential. Depending on the latter, the scalar can drive both inflation and the accelerated expansion (dS) phase in the far future. We also comment on quintessence scenarios, and flows familiar ...
متن کاملε′/ε at O(p4) in the Chiral Expansion
After updating the determination of the combination of Kobayashi-Maskawa elements Im V ∗ tsVtd according to a new estimate of the parameter B̂K , we study the CP -violating ratio ε/ε by means of hadronic matrix elements computed to O(p4) in the chiral expansion and NLO Wilson coefficients. It is the first time that this order in chiral perturbation theory is included in the analysis. The most im...
