The Electromagnetic Mass Differences of Pions and Kaons
Meson kaon electromagnetic depend on the model input high energy kaon
2014/12/23
We use the Cottingham method to calculate the pion and kaon electromagnetic mass differences with as few model dependent inputs as possible. The constraints of chiral symmetry at low energy, QCD at hi...

Isospin hypercharged axial vector current chiral perturbation theory chiral spectrum function low energy spectrum functions
2014/12/22
A new calculation of the isospin and hypercharge axial-vector current propagators [ ΔA33μν(q2) and ΔA88μν(q2)] to two loops in SU(3)×SU(3) chiral perturbation theory is used to derive chiral spectral ...

Viable range of the mass scale of the standard model
Physical parameters the higgs particle quality parameter values complex elements
2014/12/22
In theories in which different regions of the universe can have different values of certain physical parameters, we would naturally find ourselves in a region where they take values favorable for life...
Positivity bounds for the Yano-Arnowitt-Deser-Misner mass density
Vector conservation of gravity mass density energy
2014/12/20
Killing-Yano tensors are natural generalizations of Killing vectors to arbitrary rank antisymmetric tensor fields. It was recently shown that Killing-Yano tensors lead to conserved gravitational charg...
Observation of Unusual Mass Transport in Solid hcp 4He
Stop the capillary constant temperature superfluid solid atoms the melting curve
2014/12/20
Solid 4He has been created off the melting curve by growth at a nearly constant mass via the “blocked capillary” technique and growth from the 4He superfluid at constant temperature. The experimental ...
Quantum-limited mass flow of liquid He-3
Quantum fluid nano channel quantized conductance sensitive to temperature scattering matrix simulation
2014/12/19
We consider theoretically the possibility of observing unusual quantum fluid behavior in liquid 3He and solutions of 3He in 4He systems confined to nanochannels. In the case of pure ballistic flow at ...
Observation of mass transport through solid 4He
Superfluid helium cells solid temperature
2014/12/19
By use of an experimental design that provides for superfluid helium in contact with bulk hcp 4He off the melting curve, we have observed the dc transport of mass through a cell filled with solid 4He ...
Effect of Position-dependent Mass on Dynamical Breaking of Type B and Type X_2 N-fold Supersymmetry
N-fold supersymmetry Position-dependent mass Dynamical symmetry breaking Quasisolvability Exceptional orthogonal polynomials
2012/4/23
We investigate effect of position-dependent mass profiles on dynamical breaking of N-fold supersymmetry in several type B and type X_2 models. We find that N-fold supersymmetry in rational potentials ...

Saari's homographic conjecture planar equal-mass three-body problem Mathematical Physics
2011/9/1
Abstract: Donald Saari conjectured that the $N$-body motion with constant configurational measure is a motion with fixed shape. Here, the configurational measure $\mu$ is a scale invariant product of ...

Abstract: Investigations of mass segregation are of vital interest for the understanding of the formation and dynamical evolution of stellar systems on a wide range of spatial scales. Our method is ba...

2011/7/26
Abstract: We consider an inverse spectral problem for infinite linear mass-spring systems with different configurations obtained by changing the first mass. We give results on the reconstruction of th...

In Ref. [1] (by J. Alexandre) a minimal extension of (3+1)-dimensional Quantum Electrodynamics has been proposed, which includes Lorentz-Violation (LV) in the form of higher-(spatial)-derivative isotr...
