Spectrality, coupling constant analyticity and the renormalization group
Analytic structure in the strong coupling constant that emerges for some observables in QCD after duality averaging of renormalization group improved amplitudes is discussed. It is shown that perturbation theory calculations are justified for the proper observables related to the two-point correlators of hadronic currents the analytic properties of which are well-established. A particular case ...
متن کاملEffective Coupling Constant in Renormalization Group for the Quantum Electrodynamics
Effective coupling constant in quantum electrodynamics is investigated. A pole appears in the effective coupling constant for the space-like momentum if it is calculated by perturbation. The pole can be eliminated by the analytic regularization. For QED the effective coupling constant is written in terms of the scale parameter, Λ, having the dimension of mass as in the case of QCD. Λ is determi...
متن کاملRenormalization of Black Hole Entropy and of the Gravitational Coupling Constant
The quantum corrections to black hole entropy, variously defined, suffer quadratic divergences reminiscent of the ones found in the renormalization of the gravitational coupling constant (Newton constant). We consider the suggestion, due to Susskind and Uglum, that these divergences are proportional, and attempt to clarify its precise meaning. We argue that if the black hole entropy is identifi...
متن کاملcoupling constant
We calculate the π∆∆ coupling gπ0∆++∆++ using light cone QCD sum rule. Our result is gπ0∆++∆++ = (11.8 ± 2.0). We compare various model predictions. PACS numbers: 12.39.Fe, 14.20.Gk The π∆∆ coupling constant g1, like the nucleon axial charge gA, is a basic parameter which enters the loop calculation in all processes involved with delta resonance [1] in chiral perturbation theory. Unfortunately ...
متن کاملMuon capture, continuum random phase approximation, and in-medium renormalization of the axial-vector coupling constant.
We use the continuum random phase approximation to describe the muon capture on C, O and Ca. We reproduce the experimental total capture rates on these nuclei to better than 10% using the free nucleon weak form factors and two di erent residual interactions. However, the calculated rates for the same residual interactions are signi cantly lower than the data if the in-medium quenching of the ax...
