Kinematic Sum Rules for Trace Anomalies
نویسنده
چکیده
I derive a procedure to generate sum rules for the trace anomalies a and a′. Linear combinations of ∆a ≡ aUV − aIR and ∆a′ ≡ aUV − aIR are expressed as multiple flow integrals of the two-, threeand four-point functions of the trace of the stress tensor. Eliminating ∆a′, universal flow invariants are obtained, in particular sum rules for ∆a. The formulas hold in the most general renormalizable quantum field theory (unitary or not), interpolating between UV and IR conformal fixed points. I discuss the relevance of these sum rules for the issue of the irreversibility of the RG flow.

Sum Rules for Trace Anomalies and Irreversibility of the Renormalization-group Flow
The purpose of my talk is to review exact results for the trace anomalies c and a in the critical limits of supersymmetric theories, which provide non-perturbative evidence that the renormalization-group (RG) flow is irreversible, and then derive universal sum rules for c, a and a in even dimensions, formulate a theory of the irreversibility of the RG flow, recapitulate the arguments and the ev...
متن کاملSearch for Flow Invariants in Even and Odd Dimensions
A flow invariant in quantum field theory is a quantity that does not depend on the flow connecting the UV and IR conformal fixed points. We study the flow invariance of the most general sum rule with correlators of the trace Θ of the stress tensor. In even (four and six) dimensions we recover the results known from the gravitational embedding. We derive the sum rules for the trace anomalies a a...
متن کاملChiral sum rules and their phenomenology.
We present an analysis of four sum rules, each based on chiral symmetry and containing the difference ρV(s) − ρA(s) of isovector vector and axialvector spectral functions. Experimental data from tau lepton decay and electron-positron scattering identify the spectral functions over a limited kinematic domain. We summarize the status of the existing database. However, a successful determination o...
متن کاملChiral sum rules and vacuum condensates from tau-lepton decay data
QCD finite energy sum rules, together with the latest updated ALEPH data on hadronic decays of the tau-lepton are used in order to determine the vacuum condensates of dimension d = 2 and d = 4. These data are also used to check the validity of the Weinberg sum rules, and to determine the chiral condensates of dimension d = 6 and d = 8, as well as the chiral correlator at zero momentum, proporti...
متن کاملCalibration of Hardening Rules for Cyclic Plasticity
In the realm of multi-axial ratcheting, a step by step mathematical approach is developed for the parameter determination of decomposed kinematic hardening rules. For this purpose, key characteristics are mathematically derived for these hardening rules under multi-axial loading. These characteristics are then utilized to develop expressions which relate the loading history to the accumulated p...
