Average Effective Potential for the Conformal Factor
In a four dimensional theory of gravity with lagrangian quadratic in curvature and torsion, we compute the effective action for metrics of the form gμν = ρ δμν , with ρ constant. Using standard field-theoretic methods we find that one loop quantum effects produce a nontrivial effective potential for ρ. We explain this unexpected result by showing how our regularization procedure differs from th...
متن کاملThe Effective Potential for the Conformal Factor in the Standard Model and Beyond
There is a general mechanism by which certain matter fields coupled to gravity can generate a nontrivial effective potential for the conformal factor of the metric. It is based on a nonstandard regularization method, with the cutoff being defined independently of the conformal factor. This mechanism produces a coupling of the matter fields to a dilaton, and a complicated interaction between mat...
متن کاملRenormalization Group and Effective Potential in Classically Conformal Theories
Making use of a general formula for the RG improved effective (ColemanWeinberg) potential for classically conformal models and applying it to several examples of physical interest, and in particular a model of QCD coupled via quarks to a colorless scalar field, we discuss the range of validity of the effective potential as well as the issue of ‘large logarithms’ in a way different from previous...
متن کاملEffective potential for the conformal sector of quantum gravity with torsion
The effective potential which describes the conformal dynamics of quantum gravity with torsion is discussed. The phase transitions induced by the combination of torsion and curvature are investigated. The mechanism for fixing the vacuum expectation values of the metric and torsion is presented. On leave of absence from and permanent address: Department E.C.M., Faculty of Physics, Barcelona Univ...
متن کاملPredicting the Monthly Average Cumulative Distribution of the Effective Earth Radius Factor for South Africa
In previous work a model was developed to predict the annual average cumulative distribution of the effective earth radius factor, the k-factor, for telecommunications applications in South Africa. Long term meteorological radiosonde data from eight stations were used for this purpose. In this paper, the model is used to predict the cumulative effective earth radius, or k-factor, distribution f...
