Age constraints and fine tuning in variable-mass particle models
VAMP ~variable-mass particle! scenarios, in which the mass of the cold dark matter particles is a function of the scalar field responsible for the present acceleration of the Universe, have been proposed as a solution to the cosmic coincidence problem, since in the attractor regime both dark energy and dark matter scale in the same way. We find that only a narrow region in parameter space leads...
متن کاملFine Tuning in Supersymmetric Models
The solution to fine tuning is one of the principal motivations for Beyond the Standard Model (BSM) Studies. However constraints on new physics indicate that many of these BSM models are also fine tuned (although to a much lesser extent). To compare these BSM models it is essential that we have a reliable, quantitative measure of tuning. We review the measures of tuning used in the literature a...
متن کاملThe fine-tuning problems of particle physics and anthropic mechanisms
Many of the classic problems of particle physics appear in a very different light when viewed from the perspective of the multiverse. Most importantly the two great “fine tuning” problems that motivate the field are far less serious when one accounts for the required anthropic constraints which exist in a multiverse. However, the challenge then becomes to construct a realistic physical theory o...
متن کاملFine tuning in One-Higgs and Two-Higgs Standard Models
The fine-tuning principles are examined to predict the top-quark and Higgs-boson masses. The modification of the Veltman condition based on the compensation of vacuum energies is developed. It is implemented in the Standard Model and in its minimal extension with two Higgs doublets. The top-quark and Higgs-boson couplings are fitted in the SM for the lowest ultraviolet scale where the fine-tuni...
متن کاملFine Tuning Age-estimation with Global and Local Facial Features
This paper proposes an advanced age-estimation approach that combines global and local features derived from a facial image. Active Appearance Models (AAMs) technique is used to construct the global facial features, while local facial features are generated from Local Binary Pattern (LBP) encoding. Ageestimation is performed in a two-step method: coarse (initial) prediction followed by a refini...
