Renormalization Scheme and Mass Scale Independence
F. A. Chishtie, D. G. C. McKeon
We demonstrate that in the mass independent renormalization scheme. the renormalization group equations associated with the unphysical parameters that characterize the renormalizat…
Renormalization Group Summation with Heavy Fields
D. G. C. McKeon
The summation of logarithmic contributions to perturbative radiative corrections in physical processes through use of the renormalization group equation has proved to be a useful w…
Renormalization Scheme Dependence in b->u Semileptonic Decays
D. G. C. McKeon
After reviewing how the renormalization group equation can be used to sum logarithmic corrections to the decay rate for the semi-leptonic process b->u when using minimal subtractio…
Renormalization Group Determination of the Five-Loop Effective Potential for Massless Scalar Field Theory
F. A. Chishtie, D. G. C. McKeon, T. G. Steele
The five-loop effective potential and the associated summation of subleading logarithms for O(4) globally-symmetric massless field theory in the Coleman-Weinberg renormaliza…
A Unique Determination of the Effective Potential in Terms of Renormalization Group Functions
F. A. Chishtie, T. Hanif, D. G. C. McKeon +1
The perturbative effective potential V in the massless model with a global O(N) symmetry is uniquely determined to all orders by the renormalization group functions alone wh…
Stability of Subsequent-to-Leading-Logarithm Corrections to the Effective Potential for Radiative Electroweak Symmetry Breaking
F. A. Chishtie, V. Elias, R. B. Mann +2
We demonstrate the stability under subsequent-to-leading logarithm corrections of the quartic scalar-field coupling constant and the running Higgs boson mass obtained from the…
Radiative Electroweak Symmetry Breaking Beyond Leading Logarithms
V. Elias, R. B. Mann, D. G. C. McKeon +1
The top-quark Yukawa coupling is too large to permit radiative electroweak symmetry breaking to occur for small values of y, the Higgs self-coupling, to leading-logarithm order. Ho…
Radiative Corrections to the Inflaton Potential as an Explanation of Suppressed Large Scale Power in Density Perturbations and the Cosmic Microwave Background
A. Buchel, F. A. Chishtie, V. Elias +4
The Wilkinson Microwave Anisotropy Probe microwave background data suggest that the primordial spectrum of scalar curvature fluctuations is suppressed at small wavenumbers. We prop…
Optimal Renormalization-Group Improvement of Two Radiatively-Broken Gauge Theories
V. Elias, R. B. Mann, D. G. C. McKeon +1
In the absence of a tree-level scalar-field mass, renormalization-group (RG) methods permit the explicit summation of leading-logarithm contributions to all orders of the perturbat…
Transmutation of Scale Dependence into Truncation Uncertainty via RG-Improvement of the Series
V. Elias, D. G. C. McKeon, T. G. Steele
The arbitrariness in how the logarithm is defined within the QCD series for the inclusive electroproduction cross-section is shown to affect the summation to all orders in of…
Radiative Electroweak Symmetry-Breaking Revisited
V. Elias, R. B. Mann, D. G. C. McKeon +1
In the absence of a tree-level scalar-field mass, renormalization-group methods permit the explicit summation of leading-logarithm contributions to all orders of the perturbative s…
Renormalization-Group Improvement of Effective Actions Beyond Summation of Leading Logarithms
M. R. Ahmady, V. Elias, D. G. C. McKeon +2
Invariance of the effective action under changes of the renormalization scale leads to relations between those (presumably calculated) terms independent of at a given order…
Renormalization Group Summation and the Free Energy of Hot QCD
D. G. C. McKeon, A. Rebhan
Using an approach developed in the context of zero-temperature QCD to systematically sum higher order effects whose form is fixed by the renormalization group equation, we sum to a…
