Abstract :

Much of particle physics uses data from new measurements, average measured properties of gauge bosons, leptons, quarks, mesons and baryons; there are many that are new or heavily revised including those on quark-mixing matrix, top quark, muon anomalous magnetic moment, extra dimensions, particle detectors, cosmic background radiation, dark matter, cosmological parameters and big bang cosmology. The model is based on gauge theories, of which the first was quantum electrodynamics, describing the interactions of light with matter. The core element of particle physics analysis as the name suggests is the physical characteristics that form the basis of the measurement. Decoherence theorists, who use various non-standard interpretations of quantum mechanics that deny the projection postulate quantum jumps and even the existence of particles, define the measurement problem as the failure to observe superpositions such as Schr�¶dinger's cat. Measurements are described with diverse concepts in quantum physics such as; wave functions/probability amplitudes, evolving unitary and deterministic/preserving information, according to the linear Schr�¶dinger equation, superposition of states, i.e., linear combinations of wave functions with complex coefficients that carry phase information and produce interference effects/the principle of superposition, quantum jumps between states accompanied by the "collapse" of the wave function that can destroy or create information, probabilities of collapses and jumps given by the square of the absolute value of the wave function for a given state, values for possible measurements given by the eigenvalues associated with the eigenstates of the combined measuring apparatus and measured system. The expected consequence of Niels Bohr's "Copenhagen interpretation" of quantum mechanics, was to explain how our measuring instruments, which are mostly macroscopic objects and treatable with classical physics, can give us information about the microscopic world of atoms and subatomic particles like electrons and photons. Some define the problem of measurement simply as the logical contradiction between two laws describing the motion of quantum systems; the unitary, continuous, and deterministic time evolution of the Schr�¶dinger equation versus the non-unitary, discontinuous, and indeterministic collapse of the wave function. Here, I intend to present a unified dynamics framework using particles connected by constraints as the fundamental infrastructure that let us treat measurements in a unified manner.
