Optical activity of neutrinos and antineutrinos
Using the one-loop helicity amplitudes for low-energy
and scattering in the standard model with
massless neutrinos, we study the optical activity of a sea of neutrinos and
antineutrinos. In particular, we estimate the values of the index of refraction
and rotary power of this medium in the absence of dispersion.Comment: Additional reference
Photons, neutrinos and optical activity
We compute the one-loop helicity amplitudes for low-energy
scattering and its crossed channels in the standard
model with massless neutrinos. In the center of mass, with , the cross sections for these channels grow roughly
as . The scattered photons in the elastic channel are circularly
polarized and the net value of the polarization is non-zero. We also present a
discussion of the optical activity of a sea of neutrinos and estimate the
values of its index of refraction and rotary power.Comment: 9 pages, ReVTeX4, 6 figures include
Axial vector current in an electromagnetic field and low-energy neutrino-photon interactions
An expression for the axial vector current in a strong, slowly varying
electromagnetic field is obtained. We apply this expression to the construction
of the effective action for low-energy neutrino-photon interactions.Comment: 6 pages, references updated, final version to appear in Phys. Rev.
Observables from a solution of 1+3 dimensional relativistic hydrodynamics
In this paper we analyze a 1+3 dimensional solution of relativistic
hydrodynamics. We calculate momentum distribution and other observables from
the solution and compare them to measurements from the Relativistic Heavy Ion
Collider (RHIC). We find that the solution we analyze is compatible with the
data. In the last several years many numerical models were tested, but it is
the first time that an exact, parametric, 1+3 dimensional relativistic solution
is compared to data.Comment: 6 pages, 6 figures. Published in EPJ A. This work was supported by
