Using the Renormalization Group Functions to Uniquely Determine the Effective Potential in Massless Scalar Electrodynamics
F. A. Chishtie, T. Hanif, D. G. C. McKeon
It has been demonstrated that the effective potential V(ϕ) in a massless O(N) λϕ^4_4 model is determined completely by the renormalization group functions provided the renormalizat…
The Derivative Expansion of the Effective Action and the Renormalization Group Equation
F. A. Chishtie, Junji Jia, D. G. C. McKeon
The perturbative evaluation of the effective action can be expanded in powers of derivatives of the external field. We apply the renormalization group equation to the term in the e…
Tensor Self Energy in a Vector-Tensor Model
A. Buchel, F. A. Chishtie, M. Gagne-Portelance +2
The tensor self energy is computed at one loop order in a model in which a vector and tensor interact in a way that eliminates all tensor degrees of freedom. Divergencies arise whi…
On the Standard Approach to Renormalization Group Improvement
F. A. Chishtie, V. Elias, R. B. Mann +2
Two approaches to renormalization-group improvement are examined: the substitution of the solutions of running couplings, masses and fields into perturbatively computed quantities…
Radiative Corrections in a Vector-Tensor Model
F. Chishtie, M. Gagné-Portelance, T. Hanif +2
In a recently proposed model in which a vector non-Abelian gauge field interacts with an antisymmetric tensor field, it has been shown that the tensor field possesses no physical d…
The renormalization group improved effective potential in massless models
F. T. Brandt, F. A. Chishtie, D. G. C. McKeon
The effective potential is considered in massless theory. The expansion of in powers of the coupling and of the logarithm of the background field is reorga…
