چکیده
We revisit the derivation of nonlocal collision term in Boltzmann equation for spin-1/2 particles, using both Wigner-function approach by de Groot, van Leeuwen, and Weert, Kadanoff-Baym $T$-matrix approximation. Contrary to previous calculations, our results maintain full Lorentz covariance term.

Lorentz Covariant Spin Two Superspaces
Superalgebras including generators having spins up to two and realisable as tangent vector fields on Lorentz covariant generalised superspaces are considered. The latter have a representation content reminiscent of configuration spaces of (super)gravity theories. The most general canonical supercommutation relations for the corresponding phase space coordinates allowed by Lorentz covariance are...

متن کاملLorentz-covariant Hamiltonian Formalism
The dynamic of a classical system can be expressed by means of Poisson brackets. In this paper we generalize the relation between the usual non covariant Hamiltonian and the Poisson brackets to a covariant Hamiltonian and new brackets in the frame of the Minkowski space. These brackets can be related to those used by Feynman in his derivation of Maxwell's equations. The case of curved space is ...
متن کاملInfinitesimally Nonlocal Lorentz Violation
We introduce a new Lorentz-violating modification to a scalar quantum field theory. This interaction, while super-renormalizable by power counting, is fundamentally different from the interactions previously considered within the Lorentz-violating standard model extension. The Lagrange density is nonlocal, because of the presence of a Hilbert transform term; however, this nonlocality is also ve...
متن کاملFinite-Dimensional Lorentz Covariant Bifurcations
In this paper finite-dimensional Lorentz covariant bifurcation equations are constructed and their properties, solutions, and gradient structures are examined. The possible applications of these ideas and techniques to elementary particle physics are considered.
