Monopoles without magnetic charges: Finite energy monopole–antimonopole configurations in CP1 model and restricted QCD
Abstract We propose a new type of regular monopole-like field configuration in quantum chromodynamics (QCD) and CP1 model. The monopole configuration can be treated as a monopole–antimonopole pair without localized magnetic charges. An exact numeric ...

Track Orientation Density Imaging (TODI) and Track Orientation Distribution (TOD) based tractography
Abstract Ever since the introduction of the concept of fiber tractography, methods to generate better and more plausible tractograms have become available. Many modern methods can handle complex fiber architecture and take on a probabilistic...

To see symmetry in a forest of trees
Abstract The exact symmetry identities among four-point tree-level amplitudes of bosonic open string theory as derived by G.W. Moore are re-examined. The main focuses of this work are: (1) Explicit construction of kinematic configurations and a new...

Emergence of cosmic space and minimal length in quantum gravity
Abstract An emergence of cosmic space has been suggested by Padmanabhan in [1]. This new interesting approach argues that the expansion of the universe is due to the difference between the number of degrees of freedom on a holographic surface and...

Lagrangian and Geometric Analysis of Finite-time Euler Singularities
Abstract We present a numerical method of analyzing possibly singular incompressible 3D Euler flows using massively parallel high- resolution adaptively refined numerical simulations up to 81923 mesh points. Geometrical properties of Lagrangian...

Currents and charges for mixed fields
Abstract We present an analysis of currents and charges for a system of two mixed fields, both for spinless bosons and for Dirac fermions. This allows us to obtain in a straightforward way the exact field theoretical oscillation formulas exhibiting...

The non-perturbative groundstate of QCD and the local composite operator A2μ
Abstract We investigate the possibility that the dimension 2 condensate A 2 μ has a non zero non-perturbative value in Yang–Mills theory. We introduce a...

Measurement of the longitudinal and transverse cross-section in e+e− annihilation at s=35–44 GeV
Abstract An investigation of the polar angle distribution of charged hadrons is presented using data taken by the JADE experiment at the PETRA e+e− collider at centre-of-mass energies of 35 and 44 GeV. From fits to the polar angle distribution the...

Anomalies in orbifold field theories
Abstract We study the constraints on models with extra dimensions arising from local anomaly cancellation. We consider a five-dimensional field theory with a U(1) gauge field and a charged fermion, compactified on the orbifold S ...

Boundary terms in the Barrett–Crane spin foam model and consistent gluing
Abstract We extend the lattice gauge theory-type derivation of the Barrett–Crane spin foam model for quantum gravity to other choices of boundary conditions, resulting in different boundary terms, and re-analyze the gluing of 4-simplices in this...

Null-brane solutions in supergravities
Abstract We find a new class of time-dependent brane solutions in supergravities in arbitrary dimensions D. These are general intersecting light-like branes (null-branes), and their superposition and intersection rules are obtained. This is achieved ...

Problems of double-charm production in e+e− annihilation at s=10.6 GeV
Abstract Using the nonrelativistic QCD (NRQCD) factorization formalism, we calculate the color-singlet cross sections for exclusive production processes e ++e −→J/ψ+η ...

Going down from a 3-form in 16 dimensions
Abstract Group theory indicates the existence of a SO(8)×SO(7)⊂SO(16) invariant self-duality equation for a 3-form in 16 dimensions. It is a signal for interesting topological field theories, especially on 8-dimensional manifolds with holonomy group ...

Topological field patterns of the Yang–Mills theory
Abstract It is shown that the SO(3) gauge field configurations can be completely characterised by certain gauge invariant vector fields. The singularities of these vector fields describe the topological aspects of the gauge field configurations. The ...
