The IR/UV mixing in the non-commutative (NC) field theory is investigated in CarlsonCarone-Zobin (CCZ) formalism of Lorentz-invariant NC field theory provided that the fields are ‘independent’ of the ‘internal’ coordinates θ . A new regularization scheme called NC regularization is then proposed, which removes the Lorentz-invariant IR singularity by subtraction from the theory. It requires the ...

One possible feature of quantum gravity may be the violation of Lorentz invariance. In this paper we consider one particular manifestation of the violation of Lorentz invariance, namely modified dispersion relations for massive neutrinos. We show how such modified dispersion relations may affect atmospheric neutrino oscillations. We then consider how neutrino telescopes, such as ANTARES, may be...

Future experiments will use silicon sensors in the harsh radiation environment of the LHC (Large Hadron Collider) and high magnetic fields. The drift direction of the charge carriers is affected by the Lorentz force due to the high magnetic field. Also the resulting radiation damage changes the properties of the drift. In this paper measurements of the Lorentz angle of electrons and holes befor...

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 Theor...
