Deformed Symmetry in Snyder Space and Relativistic Particle Dynamics
We describe the deformed Poincare-conformal symmetries implying the covariance of the noncommutative space obeying Snyder’s algebra. Relativistic particle models invariant under these deformed symmetries are presented. A gauge (reparametrisation) independent derivation of Snyder’s algebra from such models is given. The algebraic transformations relating the deformed symmetries with the usual (u...
متن کاملTwisted Symmetry in Snyder Space and Relativistic Particle Dynamics
We describe the twisted Poincare-conformal symmetries implying the covariance of the noncommutative space obeying Snyder’s algebra. Relativistic particle models invariant under these twisted symmetries are presented. A gauge (reparametrisation) independent derivation of Snyder’s algebra from such models is given. The algebraic transformations relating the twisted symmetries with the usual (untw...
متن کاملPerturbatively Defined Effective Classical Potential in Curved Space
The partition function of a quantum statistical system in flat space can always be written as an integral over a classical Boltzmann factor exp[−βV eff cl(x0)], where V eff cl(x0) is the so-called effective classical potential containing the effects of all quantum fluctuations. The variable of integration is the temporal path average x0 ≡ β ∫ β 0 dτ x(τ ). We show how to generalize this concept...
متن کاملClassical gluodynamics in curved space–time and the soft Pomeron
QCD at the classical level possesses scale invariance which is broken by quantum effects. This “dimensional transmutation” phenomenon can be mathematically described by formulating classical gluodynamics in a curved, conformally flat, space–time with non–vanishing cosmological constant. We study QCD high–energy scattering in this theory. We find that the properties of the scattering amplitude a...
