One-loop effective potential on hyperbolic manifolds.
U.T.F. 284 Abstract: The one-loop effective potential for a scalar field defined on an ultrastatic space-time whose spatial part is a compact hyperbolic manifold, is studied using zeta-function regularization for the one-loop effective action. Other possible regularizations are discussed in detail. The renormalization group equations are derived and their connection with the conformal anomaly i...
متن کاملOne - loop effective potential of N = 1 supersymmetric theory and decoupling effects
We study the decoupling effects in N = 1 (global) supersymmetric theories with chiral superfields at the one-loop level. Examples of gauge neutral chiral superfields with minimal (renormalizable) as well as non-minimal (non-renormalizable) couplings are considered, and decoupling in gauge theories with U (1) gauge superfields that couple to heavy chiral matter is studied. We calculate the one-l...
متن کاملTwo-loop effective potential for the minimal supersymmetric standard model
I compute the complete two-loop effective potential for the minimal supersymmetric standard model in the Landau gauge. This enables an accurate determination of the minimization conditions for the vacuum expectation values of the Higgs fields. Checks on the result follow from supersymmetric limits and from renormalization-scale invariance. The renormalization group equations for the field-indep...
متن کاملOne-loop Kähler potential in non-renormalizable theories
We consider a general d=4 N=1 globally supersymmetric lagrangian involving chiral and vector superfields, with arbitrary superpotential, Kähler potential and gauge kinetic function. We compute perturbative quantum corrections by employing a component field approach that respects supersymmetry and background gauge invariance. In particular, we obtain the full one-loop correction to the Kähler po...
متن کاملOne-loop effective potential from higher-dimensional AdS black holes
We study the quantum effects in a brane-world model in which a constant curvature (in particular, a flat) brane universe is embedded in a higher-dimensional bulk AdS black hole, instead of the usual portion of the AdS5. By using zeta regularisation, we explicitly calculate the one-loop effective potential due to the bulk quantum fields and show that it leads to a non-vanishing cosmological cons...
