Conformal Unification of General Relativity and Standard Model
The unification of general relativity and standard model for strong and electroweak interactions is considered on the base of the conformal symmetry principle. The Penrose-Chernikov-Tagirov Lagrangian is used to describe the Higgs scalar field modulus and gravitation. We show that the procedure of the Hamiltonian reduction converts the homogeneous part of the Higgs field into the dynamical para...
متن کاملThe External-internal Group Quotient Structure for the Standard Model in Analogy to General Relativity
In analogy to the class structureGL( IR)/O(1, 3) for general relativity with a local Lorentz group as stabilizer and a basic tetrad field for the parametrization, a corresponding class structure GL( I C)/U(2) is investigated for the standard model with a local hyperisospin group U(2). The lepton, quark, Higgs and gauge fields, used in the standard model, cannot be basic in a coset interpretatio...
متن کاملThe ecliptic in general relativity
This article deals with relativistic effects on the motion of ecliptic. It is pointed out that the traditional definition of ecliptic can be used in the framework of general relativity: in general the definition of ecliptic is coordinate dependent and proper quasi-Cartesian coordinates should be adopted to avoid ambiguity of the definition. We derive equations that determine the motion of the e...
متن کاملThe Standard-model Extension and Tests of Relativity *
The Standard-Model Extension, or SME, is a general framework for the study of Lorentz violation in physics. A broad variety of experiments is able to access the SME coefficient space. This proceedings briefly summarizes theory and experiments aimed at testing Special Relativity by measuring these coefficients. Lorentz symmetry is a central feature of the existing theories of gravitation and par...
متن کاملPrediction in general relativity
Several authors have claimed that prediction is essentially impossible in the general theory of relativity, the case being particularly strong, it is said, when one fully considers the epistemic predicament of the observer. Each of these claims rests on the support of an underdetermination argument and a particular interpretation of the concept of prediction. I argue that these underdeterminati...
