Three questions on Lorentz violation
نویسنده
چکیده
We review the basics of the two most widely used approaches to Lorentz violation the Standard Model Extension and Noncommutative Field Theory and discuss in some detail the example of the modified spectrum of the synchrotron radiation. Motivated by touching upon such a fundamental issue as Lorentz symmetry, we ask three questions: What is behind the search for Lorentz violation? Is String Theory a physical theory? Is there an alternative to Supersymmetry? Invited lecture at DICE2006 Piombino Italy, September 11-15, 2006

The Relativistic Effects on the Violation of the Bell's Inequality for Three Qubit W State
In this paper we are going to calculate the correlation function and Bell'sinequality for three qubit W state under the Lorentz transformations. This survey is basedon the introduction of two different expressions of spin observable were presented byLee-Young and Kim-Son.

Non-commutative field theory as a theory including the Lorentz violation can be constructed in two different ways. In the first method, the non-commutative fields are the same as the ordinary ones while the gauge group is restricted to U(n). For example, the symmetry group of standard model in non-commutative space is U(3)×(2)×U(1) which can be reduced to SU(3)×SU(2)×U(1) by two appropriate spo...
متن کاملNeutrino Oscillations from Strings and Other Funny Things
I will discuss three related unconventional ways to generate neutrino oscillations:(1)Equivalence principle violation by the string dilaton field (2) Violation of Lorentz Invariance and (3)Equivalence principle violation through a non-universal tensor neutrino-gravity coupling. These unorthodox oscillation mechanisms are shown to be viable at the level of our present experimental knowledge and ...
متن کاملHigh Energy Constraints on Lorentz Symmetry Violations
Lorentz violation at high energies might lead to non linear dispersion relations for the fundamental particles. We analyze observational constraints on these without assuming any a priori equality between the coefficients determining the amount of Lorentz violation for different particle species. We focus on constraints from three high energy processes involving photons and electrons: photon de...
متن کاملAstrophysical Bounds on Planck Suppressed Lorentz Violation
This article reviews many of the observational constraints on Lorentz symmetry violation (LV). We first describe the GZK cutoff and other phenomena that are sensitive to LV. After a brief historical sketch of research on LV, we discuss the effective field theory description of LV and related questions of principle, technical results, and observational constraints. We focus on constraints from h...
