The Nature of Nonperturbative Effects in Lepton-nucleon Scattering*
There is evidence for substantial nonperturbative effects in the structure functions extracted from deep-inelastic lepton-nucleon scattering. These effects have a major impact on us and A determinations. Results which I reported previously for pN and vN scattering (Fz and xF3) are extended to include ed data which are at lower W2 and higher x and have extremely high statistics. Possible analyti...
متن کاملNonperturbative propagators in quantum chromodynamics.
Leading nonperturbative corrections to the quark and gluon propagators are derived following the assumption that the nonperturbative QCD vacuum can be described in terms of non-vanishing vacuum expectation values for the composite operators [T&I and [GEY]. Th e nonperturbative quark propagator can be described in terms of a running quark mass and a running normalization function. These quantiti...
متن کاملThe Nonperturbative Quantum de Sitter Universe
The dynamical generation of a four-dimensional classical universe from nothing but fundamental quantum excitations at the Planck scale is a long-standing challenge to theoretical physicists. A candidate theory of quantum gravity which achieves this goal without invoking exotic ingredients or excessive fine-tuning is based on the nonperturbative and background-independent technique of Causal Dyn...
متن کاملNonperturbative Quantum Field Theory on the Lattice
These lectures provide an introduction to lattice methods for nonperturbative studies of quantum field theories, with an emphasis on Quantum Chromodynamics. Lecture 1 (Ch. 2): gauge field basics; lecture 2 (Ch. 3): Abelian duality with a lattice regulator; (Ch. 4) simple lattice intuition; lecture 3 (Ch. 5): standard methods (and results) for hadron spectroscopy; lecture 4 (Ch. 6): bare actions...
متن کاملThe physical Hamiltonian in nonperturbative quantum gravity.
A quantum Hamiltonian which evolves the gravitational field according to time as measured by constant surfaces of a scalar field is defined through a regularization procedure based on the loop representation, and is shown to be finite and diffeomorphism invariant. The problem of constructing this Hamiltonian is reduced to a combinatorial and algebraic problem which involves the rearrangements o...
