mass difference from a dispersion relation
We study the Standard Model prediction for the mass difference between the two neutral D meson mass eigenstates, ∆m. We derive a dispersion relation based on heavy quark effective theory that relates ∆m to an integral of the width difference of heavy mesons, ∆Γ, over varying values of the heavy meson mass. Modeling the mD-dependence of certain D decay partial widths, we investigate the effects ...
متن کاملCompact Upwind Biased Dispersion Relation Preserving Finite Difference Schemes
A class of higher-order compact upwind biased finite difference (FD) schemes based on the Taylor Series Expansion is developed in this work. The numerical accuracy of this family of compact upwind biased FD schemes is demonstrated by means of Fourier analysis wherein it is shown that these FD schemes have very low dispersion errors over a relatively large bandwidth of wave numbers as compared t...
متن کاملScalar Wave Equation Modeling with Time–Space Domain Dispersion-Relation-Based Staggered-Grid Finite-Difference Schemes
The staggered-grid finite-difference (SFD) method is widely used in numerical modeling of wave equations. Conventional SFD stencils for spatial derivatives are usually designed in the space domain. However, when they are used to solve wave equations, it becomes difficult to satisfy the dispersion relations exactly. Liu and Sen (2009c) proposed anewSFDscheme for one-dimensional (1D) scalarwaveeq...
متن کاملDifference Between Relation And Relation Schema
What is the difference between specialization and generalization with respect to database? 8. Differentiate between a relation schema and a relation instance. What is the difference between an entity relationship model and a relational model? and also for a mathematical ordered-tuple set representing one, is a "relation". represents information as tuples, directly mapped to a relational schema....
متن کاملA Detailed Investigation of Particulate Dispersion from Kerman Cement Plant
The aim of this study was to investigate the particulate dispersion from Kerman Cement Plant. The upwind – downwind method was used to measure particle concentration and a cascade impactor was applied to determine particle size distribution. An Eulerian model, Gaussian plume model and an artificial neural network have been used to compute and predict concentration of PM10 from Ke...
