On Higgs decays to hadrons and the R-ratio at N4LO

open access: yesJournal of High Energy Physics, 2017
We present the first determination of Higgs-boson decay to hadrons at the next-to-next-to-next-to-next-to-leading order of perturbative QCD in the limit of a heavy top quark and massless light flavours.

Linear Perturbations of the Bloch Type of Space-Periodic Magnetohydrodynamic Steady States. II. Numerical Results

open access: yesRussian Journal of Earth Sciences, 2023
We consider Bloch eigenmodes of three linear stability problems: the kinematic dynamo problem, the hydrodynamic and MHD stability problem for steady space-periodic flows and MHD states comprised of randomly generated Fourier coefficients and having energy ...

Mathematical Theory of Exchange-driven Growth [PDF]

open access: yes, 2018
Exchange-driven growth is a process in which pairs of clusters interact and exchange a single unit of mass. The rate of exchange is given by an interaction kernel $K(j,k)$ which depends on the masses of the two interacting clusters.

Linear perturbations of the Bloch type of space-periodic magnetohydrodynamic steady states. I. Mathematical preliminaries

open access: yesRussian Journal of Earth Sciences, 2023
We consider Bloch eigenmodes in three linear stability problems: the kinematic dynamo problem, the hydrodynamic and MHD stability problem for steady space-periodic flows and MHD states. A Bloch mode is a product of a field of the same periodicity, as the

Linear perturbations of the Bloch type of space-periodic magnetohydrodynamic steady states. III. Asymptotics of branching

open access: yesRussian Journal of Earth Sciences, 2023
The previous paper of this series presented the results of a numerical investigation of the dependence of the dominant growth rates of Bloch eigenmodes on the diffusivity parameters (the molecular viscosity ν and molecular magnetic diffusivity η) in ...

A Glimpse at Mathematical Diffraction Theory

open access: yes, 2002
Mathematical diffraction theory is concerned with the analysis of the diffraction measure of a translation bounded complex measure $\omega$. It emerges as the Fourier transform of the autocorrelation measure of $\omega$.

Mathematical Diffraction Theory [PDF]

open access: yesActa Crystallographica Section A Foundations and Advances, 2014
In this talk we will review some of the recent progress in Diffraction Theory. We will start by introducing some general structures which give rise to Bragg peak diffraction, and we will discuss the connection between these structures and the concept of almost periodicity for measures.

Spectral theory of a mathematical model in Quantum Field Theory for any spin [PDF]

open access: yes, 2015
In this paper we use the formalism of S.Weinberg in order to construct a mathematical model based on the weak decay of hadrons and nuclei. In particular we consider a model which generalizes the weak decay of the nucleus of the cobalt.

The prospects for mathematical logic in the twenty-first century [PDF]

open access: yes, 2001
The four authors present their speculations about the future developments of mathematical logic in the twenty-first century. The areas of recursion theory, proof theory and logic for computer science, model theory, and set theory are discussed ...

High Resolution Seismicity Smoothing Method for Seismic Hazard Assessment

open access: yesRussian Journal of Earth Sciences
A high resolution smoothing method is proposed for performing local estimates of the parameters of the Gutenberg-Richter law (GR). Using this method, the smoothing radius can be chosen large enough to ensure that the condition of applicability of GR law ...
