Anomalous Specific Heat in Ultradegenerate Qed and Qcd
نویسنده
چکیده
We discuss the origin of the anomalous T lnT behavior of the low-temperature entropy and specific heat in ultradegenerate QED and QCD and report on a recent calculation which is complete to leading order in the coupling and which contains an infinite series of anomalous terms involving also fractional powers in T . This result involves dynamical hard-dense-loop resummation and interpolates between Debye screening effects at larger temperatures and non-Fermi-liquid behavior from only dynamically screened magnetic fields at low temperature.

Hadronic light-by-light scattering contribution to the muon anomalous magnetic moment from lattice QCD.
The most compelling possibility for a new law of nature beyond the four fundamental forces comprising the standard model of high-energy physics is the discrepancy between measurements and calculations of the muon anomalous magnetic moment. Until now a key part of the calculation, the hadronic light-by-light contribution, has only been accessible from models of QCD, the quantum description of th...
متن کاملExtended BRS Symmetry and Gauge Independence in On-Shell Renormalization Schemes
Extended BRS symmetry is used to prove gauge independence of the fermion renormalization constant Z2 in on-shell QED renormalization schemes. A necessary condition for gauge independence of Z2 in on-shell QCD renormalization schemes is formulated. Satisfying this necessary condition appears to be problematic at the three-loop level in QCD. In on-shell schemes, the fermion mass renormalization Z...

The large N f self-consistency programme is reviewed. As an application the QCD β-function is computed at O(1/N f) and the anomalous dimensions of polarized twist-2 singlet operators are determined at the same order.
متن کاملThe QED vacuum polarization function at four loops and the anomalous magnetic moment at five loops
The anomalous moment of the muon is one of the most fundamental observables. It has been measured experimentally with a very high precision and on theory side the contributions from perturbative QED have been calculated up to five-loop level by numerical methods. Contributions to the muon anomalous magnetic moment from certain diagram classes are also accessible by alternative methods. In this ...
متن کاملThe ∆s = 1 Effective Hamiltonian including Next-to-leading Order Qcd and Qed Corrections
In this paper we present a calculation of the ∆S = 1 effective weak Hamiltonian including next-to-leading order QCD and QED corrections. At a scale µ of the order of few GeV, the Wilson coefficients of the operators are given in terms of the renormalization group evolution matrix and of the coefficients computed at a large scale ∼ M W. The expression of the evolution matrix is derived from the ...
