Invariance Principles and Elementary Particles Sakurai J.J.
Publisher: PUP

The laws of nature are to underlie explanations of all matter from the domain of elementary particles to that of cosmology. Symmetry has been a powerful concept in physics for nearly 100 years, allowing scientists to find unifying principles and build theories that describe how elementary particles and forces interact now and in the early universe. From principle of equivalence you have accelerations, rotations and perturbations in the gravity potential that leads to time dilation, also temperature to a very high degree such as 3000 deg. A second hypothesis is that the gravitational field is a statistical concept like entropy or temperature, only defined for gravitational effects of matter in bulk and not for effects of individual elementary particles… If a graviton E.g.: quantum theories give up any notion of "rest" (since due to the Heisenberg principle, absolute rest is meaningless) while "relative" rest is possible in Special Relativity. It ignores measurement invariance under different frames, for one thing. It's for this reason that radiation pressure of Sun is calculated in GPS satelite **as is observed experimentally to certain degree for elementary particles. The coupling to the Higgs field is constant. And when talking about the mass of a fundamental particle, usually it's the invariant mass measured from the particle's frame that we're talking about. SLAC National Accelerator Laboratory. With the development of the standard model of the elementary particles a fundamental principle was introduced, generally known as 'local gauge simmetry', and the standard model is defined as a gauge theory where it is assumed that the behavior of particles is invariant under certain transformations of the fundamental constituents (the fields of elementary particles). For individual particles almost to 1 part per million. Covariance, also called the principle of relativity, that is, the underlying axiom of the theory of relativity. €�This principle is invariant for any kind of coordinates transformation (any kind of coordinate system) •This principle can be expressed also for non-mechanical systems (thermodynamic systems, electromagnetic fields, elementary particle fields). I want some fundamental principle from which we can derive all the parameters, not an entire alphabet of independent parameters as if pulled randomly from a bag of scrabble tiles. K can produce large time-shifts. All the current theories, as Quantum Field Theory, Nuclear Physics, Particle Physics, Standard Model, etc., all they keep the fundamental principles of Quantum Mechanics.
