Which of these do you expect to have the greatest future influence on research? Papers are listed alphabetically by author. A. Barrett and Connes These are paired in the poll, since Barrett and Connes arrived at the same result at the same time. http://arxiv.org/abs/hep-th/0608221 A Lorentzian version of the non-commutative geometry of the standard model of particle physics Barrett http://arxiv.org/abs/hep-th/0608226 Noncommutative Geometry and the standard model with neutrino mixing Connes B. Freidel et al http://arxiv.org/abs/gr-qc/0607014 Particles as Wilson lines of gravitational field Freidel, Kowalski-Glikman, Starodubtsev 19 pages, to be published in Phys. Rev. D "Since the work of Mac-Dowell-Mansouri it is well known that gravity can be written as a gauge theory for the de Sitter group. In this paper we consider the coupling of this theory to the simplest gauge invariant observables that is, Wilson lines. The dynamics of these Wilson lines is shown to reproduce exactly the dynamics of relativistic particles coupled to gravity, the gauge charges carried by Wilson lines being the mass and spin of the particles. Insertion of Wilson lines breaks in a controlled manner the diffeomorphism symmetry of the theory and the gauge degree of freedom are transmuted to particles degree of freedom." C. Gambini et al http://arxiv.org/abs/quant-ph/0608243 Relational physics with real rods and clocks and the measurement problem of quantum mechanics Rodolfo Gambini, Jorge Pullin 19 pages "The use of real clocks and measuring rods in quantum mechanics implies a natural loss of unitarity in the description of the theory. We briefly review this point and then discuss the implications it has for the measurement problem in quantum mechanics. The intrinsic loss of coherence allows to circumvent some of the usual objections to the measurement process as due to environmental decoherence." D. Smolin http://arxiv.org/abs/quant-ph/0609109 Could quantum mechanics be an approximation to another theory? Lee Smolin 10 pages "We consider the hypothesis that quantum mechanics is an approximation (accurate only for the description of subsystems of the universe) to another, cosmological theory. Quantum theory is then to be derived from the cosmological theory by averaging over variables which are not internal to the subsystem, which may be considered non-local hidden variables. We find conditions for arriving at quantum mechanics through such a procedure. The key lesson is that the effect of the coupling to the external degrees of freedom introduces noise into the evolution of the system degrees of freedom, while preserving a notion of averaged conserved energy and time reversal invariance. These conditions imply that the effective description of the subsystem is Nelson's stochastic formulation of quantum theory. We show that Nelson's formulation is not, by itself, a classical stochastic theory as the conserved averaged energy is not a linear function of the probability density. We also investigate an argument of Wallstrom posed against the equivalence of Nelson's stochastic mechanics and quantum mechanics and show that, at least for a simple case, it is in error."
