Title: | Chiral fermions in noncommutative electrodynamics: Renormalizability and dispersion | Authors: | Burić, Maja Latas, Duško Radovanović, Voja Trampetić, Josip |
Issue Date: | 23-Feb-2011 | Journal: | Physical Review D - Particles, Fields, Gravitation and Cosmology | Abstract: | We analyze quantization of noncommutative chiral electrodynamics in the enveloping algebra formalism in linear order in noncommutativity parameter θ. Calculations show that divergences exist and cannot be removed by ordinary renormalization; however, they can be removed by the Seiberg-Witten redefinition of fields. Performing redefinitions explicitly, we obtain renormalizable Lagrangian and discuss the influence of noncommutativity on field propagation. Noncommutativity affects the propagation of chiral fermions only: half of the fermionic modes become massive and birefringent. © 2011 American Physical Society. |
