Field Propagator in a Quantized Space - Time
We consider in detail the analytic behaviour of the non-interacting massless scalar field two-point function in H.S. Snyder's discretized non-commuting spacetime. The propagator we find is purely real on the Euclidean side of the complex p 2 plane and goes like 1/p 2 as p 2 → 0 from either the Euclidean or Minkowski side. The real part of the propagator goes smoothly to zero as p 2 increases to...
متن کاملGraviton propagator in loop quantum gravity
We compute some components of the graviton propagator in loop quantum gravity, using the spinfoam formalism, up to some second order terms in the expansion parameter.
متن کاملProgress on Two-Loop Non-Propagator Integrals
At variance with fully inclusive quantities, which have been computed already at the twoor three-loop level, most exclusive observables are still known only at one loop, as further progress was hampered up to very recently by the greater computational problems encountered in the study of multi-leg amplitudes beyond one loop. We discuss the progress made lately in the evaluation of two-loop mult...
متن کاملThe LQG – String: Loop Quantum Gravity Quantization of String Theory I. Flat Target Space
We combine I. background independent Loop Quantum Gravity (LQG) quantization techniques, II. the mathematically rigorous framework of Algebraic Quantum Field Theory (AQFT) and III. the theory of integrable systems resulting in the invariant Pohlmeyer Charges in order to set up the general representation theory (superselection theory) for the closed bosonic quantum string on flat target space. W...
متن کاملPhase Representation for the Finite Quantum Propagator
An ordinary unambiguous integral representation for the finite propagator of a quantum system is obtained by path integrating in phase space. The skeletonization of the canonical action by means of pieces described by a complete solution of the Hamilton-Jacobi equation leads to a simple composition law that reduces the multiple integration to a sole one. Thus the finite quantum propagator can b...
