Tensor gauge boson production in high energy collisions

We calculated the leading-order cross section for the helicity two tensor gauge bosons production in fermion pair annihilation process. We compare this cross section with a similar annihilation processes in QED with two photons in the final state and with two gluons in QCD.Comment: LaTeX, 19 pages, 3 figures, typos remove

Connection between non-Abelian tensor gauge fields and open strings

We compare the structure of the tree level scattering amplitudes in non-Abelian tensor gauge field theory and in open string theory with Chan-Paton charges. We limit ourselves considering only lower rank tensor fields in both theories. We identify the symmetric and antisymmetric components of the second rank tensor gauge field with the string excitations on the third and forth levels. In the process of this identification we have been selecting only those parts of the tree level scattering amplitudes in the open string theory which have dimensionless coupling constants in four dimensions. It seems that this subclass of tree level scattering amplitudes may provide important information about the structure of the open string theory and most probably it is equivalent to the non-Abelian tensor gauge field theory.Comment: 30 pages, 5 figures, published versio

Propagating modes of non-Abelian tensor gauge field of second rank

In the recently proposed extension of the YM theory, non-Abelian tensor gauge field of the second rank is represented by a general tensor whose symmetric part describes the propagation of charged gauge boson of helicity two and its antisymmetric part - the helicity zero charged gauge boson. On the non-interacting level these polarizations are similar to the polarizations of the graviton and of the Abelian antisymmetric B field, but the interaction of these gauge bosons carrying non-commutative internal charges cannot be directly identified with the interaction of gravitons or B field. Our intention here is to illustrate this result from different perspectives which would include Bianchi identity for the corresponding field strength tensor and the analysis of the second-order partial differential equation which describes in this theory the propagation of non-Abelian tensor gauge field of the second rank.Comment: 22 pages, Latex fil
