The Effective Potential, the Renormalisation Group and Vacuum Stability
We review the calculation of the the effective potential with particular emphasis on cases when the tree potential or the renormalisation-group-improved, radiatively corrected potential exhibits non-convex behaviour. We illustrate this in a simple Yukawa model which exhibits a novel kind of dimensional transmutation. We also review briefly earlier work on the Standard Model. We conclude that, d...
متن کاملVacuum Energies and Effective Potential in Light-Cone Field Theories
Vacuum energies are computed in light-cone field theories to obtain effective potentials which determine vacuum condensate. Quantization surfaces interpolating between the light-like surface and the usual spatial one are useful to define the vacuum energies unambiguously. The GrossNeveu, SU(N) Thirring, and O(N) vector models are worked out in the large N limit. The vacuum energies are found to...
متن کاملVacuum effective action and inflation
We consider vacuum quantum effects in the Early Universe, which may lead to inflation. The inflation is a direct consequence of the supposition that, at high energies, all the particles can be described by the weakly interacting, massless, conformally invariant fields. We discuss, from the effective field theory point of view, the stability of inflation, transition to the FRW solution, and also...
متن کاملCompositeness Condition and Vacuum Stability
We consider what occurs when we remove one of the compositeness conditions proposed by Bardeen, Hill and Lindner that leads to predictions for the top quark mass conflicting with the experimental value. Through this consideration the condition for the Higgs particle to be the composite particle is reconsidered. We show that in this case, (I) the Higgs-Yukawa system of the standard model becomes...
متن کاملEffective potential and stability of the rigid membrane.
The calculation of the effective potential for fixed-end and toroidal rigid p-branes is performed in the one-loop as well as in the 1/d approximations. The analysis of the involved zeta-functions (of inhomogeneous Epstein type) which appear in the process of regularization is done in full detail. Assymptotic formulas (allowing only for exponentially decreasing errors of order ≤ 10) are found wh...
