SU(3) baryon chiral perturbation theory and long distance regularization
Chiral perturbation theory the low energy goldstein boson
2014/12/22
The use of SU(3) chiral perturbation theory in the analysis of low energy meson-baryon interactions is discussed. It is emphasized that short distance effects, arising from propagation of Goldstone bo...
Long distance regularization in chiral perturbation theory with decuplet fields
Baryon chiral perturbation theory the octet axial vector coupling magnetic
2014/12/20
We investigate the use of long distance regularization in SU(3) baryon chiral perturbation theory with decuplet fields. The one-loop decuplet contributions to the octet baryon masses, axial-vector cou...
Long distance chiral corrections in beta meson amplitudes
Long distance physics meson area of computational physics quality
2014/12/20
We discuss the chiral corrections to fB and BB with particular emphasis on determining the portion of the correction that arises from long distance physics. For very small pion and kaon masses all of ...
Short-distance analysis of D-0-D-0 mixing
The standard model the quality of the neutral meson amplitude spiral
2014/12/20
We study the Standard Model short-distance prediction for the mass and lifetime differences between the two neutral D meson mass eigenstates. We find that, despite αs/4π suppression, next-to-leading o...
Long distance effects and strangeness in the nucleon
To calculate the magnetic protons momentum space separation separation
2014/12/20
We discuss the calculation of the strange magnetic radius of the proton in chiral perturbation theory. In particular, we investigate the low-energy component of the loop integrals involving kaons. We ...
Long Distance Effects in Mixed Electromagnetic-Gravitational Scattering
Scattering dispersed particles the spin configurations
2014/12/19
Using the methods of effective field theory we examine long range effects in mixed electromagnetic-gravitational scattering. Recent calculations which have yielded differing results for such effects a...
Space-Efficient Approximation Scheme for Circular Earth Mover Distance
Space-Efficient Approximation Scheme Earth Mover Distance
2012/12/4
The Earth Mover Distance (EMD) between point sets A and B is the minimum cost of a bipartite matching between A and B. EMD is an important measure for estimating similarities between objects with quan...
Intermediate distance correlators in hot Yang-Mills theory
Intermediate distance correlators hot Yang-Mills theory
2011/1/7
Lattice measurements of spatial correlation functions of the operators FF and FF-dual in thermal SU(3) gauge theory have revealed a clear difference between the two channels at "intermediate" distance...
Long-distance behavior of temperature correlation functions in the one-dimensional Bose gas
Long-distance behavior temperature correlation functions
2010/12/27
We describe a Bethe ansatz based method to derive, starting from a multiple integral representation, the long-distance asymptotic behavior at finite temperature of the density-density correlation fun...

A Series Solution to the Luminosity Distance in a Flat LCDM Universe
Cosmological distances Numerical methods
2010/12/21
Cosmological observations indicate that our universe is flat and dark energy (DE)dominated at present. The luminosity distance plays an important role in the investigation of the evolution and structu...

metric tensor four-simplex
2010/12/20
We seek for an alternative to the metric tensor gμ as a fundamental geometrical object in fourdimensional Riemannian manifolds. We suggest that the metric tensor gμ (P) at a given point P of a manif...
Design of a 1.2 GSPS single-channel real-time long-distance transmission sampling system for fast-transient signal
fast-transient signal nanosecond digital forward-sampling real-time long-distance transmission
2009/8/14
This article has introduced the origin and speciality of fast-transient signal, and told the meaning of researching on fast-transient signal. The main troubles of sampling on fast-transient signal is...
On the Contractivity of Hilbert-Schmidt distance under open system dynamics
Hilbert-Schmidt distance system dynamics
2010/4/12
We show that the Hilbert-Schmidt distance, unlike the trace distance, between quantum states is generally not monotonic for open quantum systems subject to Lindblad semigroup dynamics. Sufficient cond...
Extracting Spooky-activation-at-a-distance from Considerations of Entanglement
Spooky-activation-at-a-distance Considerations of Entanglement
2010/4/16
Following an early claim by Nelson & McEvoy \cite{Nelson:McEvoy:2007} suggesting that word associations can display `spooky action at a distance behaviour', a serious investigation of the potentially ...
