چکیده
We present a classical formalism describing two-time physics with background gauge fields. The formalism has an irreducible version that can be used as a starting point for the construction of a quantized two-time physics theory with a minimum length in a noncommutative Lorentz-covariant space-time.

We study the possibility of introducing the classical analogue of Sny-der's Lorentz-covariant noncommutative space-time in two-time physics theory. In the free theory we find that this is possible because there is a broken local scale invariance of the action. When background gauge fields are present, they must satisfy certain conditions very similar to the ones first obtained by Dirac in 1936....

We show for the first time that the induced parity–even Lorentz invariance violation can be unambiguously calculated in the physically justified and minimally broken dimensional regularization scheme, suitably tailored for a spontaneous Lorentz symmetry breaking in a field theory model. The quantization of the Lorentz invariance violating quantum electrodynamics is critically examined and shown...

The NNLO QCD corrections to the e + e − → 3 jets can be decomposed according to their colour factors. Out of the seven colour factors, three are of QED-type: 1/N 2 , NF /N and N 2 F. We use the antenna subtraction method to compute these contributions, providing complete expressions for the subtraction terms in NF /N and N 2 F .
