A solution has been obtained for the spatial and temporal distribution function for a pulsed fully collimated beam propagating through a homogeneous medium with Gaussian ...

Dyson–Schwinger equations are important tools for non-perturbative analyses of quantum field theories. For example, they are very useful for investigations in quantum ...

Abstract: We demonstrate the effectivity of the covariant background field method by means of an explicit calculation of the 3-loop beta-function for a pure Yang-Mills ...

Advanced tools for parameter estimation in mathematical models are available in applied mathematics and statistics, but not well integrated in spectroscopy. We realized this ...

For the investigation of higher order Feynman integrals, potentially with tensor structure, it is highly desirable to have numerical methods and automated tools for ...

We assume that New Physics effects are parametrized within the Standard Model Effective Field Theory (SMEFT) written in a complete basis of gauge invariant operators up to ...

This article summarizes new features and enhancements of the first major update of Package-X. Package- X 2.0 can now generate analytic expressions for arbitrarily high rank ...

The msprop program presented in this work is capable of solving the Maxwell–Schrödinger equations for one or several laser fields propagating through a medium of quantum ...

A model is introduced for estimating the nitrogen oxides (NOx 5 NO 1 NO2) production from a lightning return stroke channel. A realistic modified transmission line model ...

We report on further development of the 'StandardPhysicalConstants' package, presented at IMS2001. We address these issues: package structure; current status of the physical ...
