Phenomenology of the equivalence principle with light scalars
Scalar particles of light the coupling strength scalar atoms coupling system the coupling
2014/12/18
Light scalar particles with couplings of sub-gravitational strength, which can generically be called 'dilatons', can produce violations of the equivalence principle. However, in order to understand ex...
Mass matrices of twice four families of quarks and leptons, scalars and gauge fields as predicted by the ''spin-charge-family-theory''
Mass matrices scalars spin-charge-family-theory
2010/12/27
The theory unifying spin and charges and predicting families, proposed as a new way to explain the assumptions of the standard model of the electroweak and colour interactions, predicts at the low ene...
The cosmological backreaction: gauge (in)dependence, observers and scalars
The cosmological backreaction gauge (in)dependence observers
2010/12/27
We discuss several issues related to a recent proposal for defining classical spatial averages to be used in the so-called cosmological backreaction problem. In the large averaging-volume limit all ga...

In this work we construct the scattering amplitude T0 0 with regular analytical properties in the s complex plane, that describes simultaneously the data on the scattering.

In this work we construct the scattering amplitude T0 0 with regular analytical properties in the s complex plane, that describes simultaneously the data on the scattering, ! 00 decay and ...
We review some recent results for a class of fluid mechanics equations called active scalars, with fractional dissipation. Our main examples are the surface quasi-geostrophic equation, the Burgers equ...
Nonlocal maximum principles for active scalars
Nonlocal maximum principles active scalars
2010/11/29
Active scalars appear in many problems of fluid dynamics. The most common examples of active scalar equations are 2D Euler, Burgers, and 2D surface quasi-geostrophic equations. Many questions about re...
Nature of light scalars through photon-photon collisions
linear sigma model light scalar mesons four-quark states two photon production mechanisms
2010/5/7
The surprising thing is that arising almost 50 years ago from the linear sigma model (LSM) with spontaneously broken chiral symmetry, the light scalar meson problem has become central in the nonpertur...
Ocean Turbulence. Part II: Vertical Diffusivities of Momentum, Heat, Salt, Mass, and Passive Scalars
Ocean Turbulence Momentum Heat Salt Mass Passive Scalars
2008/5/28
A Reynolds stress–based model is used to derive algebraic expressions for the vertical diffusivities Kα(α = m, h, s) for momentum, heat, and salt. The diffusivities are expressed as
Kα(Rρ, N, RiT, )

A note on the potential transport of scalars and organisms by surface waves
potential transport scalars organisms surface waves
2014/5/19
Wave-induced transport that is not directly reflected in Eulerian current measurements, an effect known as Stokes drift, may play a significant role in the transport of organisms and solutes in the ne...
