Top quark effects on the virtual photon structure function at ILC
Abstract We investigated top quark effects on virtual photon structure functions by pQCD. We include the top quark mass effects on the virtual photon structure function with the quark parton model and with the operator product expansion up to the...

Photon production from non-equilibrium disoriented chiral condensates in a longitudinal expansion: A theoretic framework
Abstract A theoretical framework is developed for treating the quantization of the photons in a spacetime with a longitudinal expansion. This can be used to study the production of the photons through the non-equilibrium relaxation of a disoriented...

Birefringence and noncommutative structure of space–time
Abstract We analyze the phenomenon of birefringence of the electromagnetic field in the context of noncommutative geometry, using as background a deformed pp-wave solution to noncommutative Einsteinʼs equations. The light-cone structure is...

Comparison of kaon and pion valence quark distributions in a statistical model
Abstract We have calculated the Bjorken-x dependence of the kaon and pion valence quark distributions in a statistical model. Each meson is described by a Fock state expansion in terms of quarks, antiquarks and gluons. Although Drell–Yan experiments ...

Random geometry, quantum gravity and the Kähler potential
Abstract We propose a new method to define theories of random geometries, using an explicit and simple map between metrics and large hermitian matrices. We outline some of the many possible applications of the formalism. For example, a...

Fast stray field computation on tensor grids
Abstract A direct integration algorithm is described to compute the magnetostatic field and energy for given magnetization distributions on not necessarily uniform tensor grids. We use an analytically-based tensor approximation approach for...

Improving the Precision of a Compact Subsampling Impedance Analyzer for Resonating Sensors
Abstract In recent years, compact and precise impedance measurement electronics have proved to be reasonable alternatives for dedicated measurement tasks like impedance measurement of resonant sensors. In this contribution, the design of a compact...

First measurement of the helicity dependence of 3He photoreactions in the resonance region
Abstract The first measurement of the helicity dependence of the total inclusive 3He photo-absorption cross section and of the partial cross sections for several reaction channels was carried out at MAMI (Mainz) in the photon energy range between...

Steady Laminar Boundary Layer Flow over an Impulsively Stretching Surface Enclosed by Strong Magnetic Field
Abstract The problem of steady incompressible and laminar boundary layer flow over an impulsively stretching surface embedded a strong magnetic field of an electrically conducting Newtonian fluid in the presence of induced magnetic field has been...

Dynamical realizations of l-conformal Newton–Hooke group
Abstract The method of nonlinear realizations and the technique previously developed in [A. Galajinsky, I. Masterov, Nucl. Phys. B 866 (2013) 212, arXiv:1208.1403] are used to construct a dynamical system without higher derivative terms, which holds ...

Burgers-like equation for spontaneous breakdown of the chiral symmetry in QCD
Abstract We link the spontaneous breakdown of chiral symmetry in Euclidean QCD to the collision of spectral shock waves in the vicinity of zero eigenvalue of the Dirac operator. The mechanism, originating from complex Burgerʼs-like equation for...
