On the K-term and dispersion ratios of semi-regular variables
Optical velocities of semi-regular (SR) and irregular (Lb) variables are analysed for a K-term. There is evidence for a dependence upon stellar period. Absorption lines in shorter period non-emission SR variables are ...
Neutrino and antineutrino elastic scattering and photoneutrino reactions
The processes ν ν → ν ν , ν ¯ ν → ν ¯ ν , ν ¯ ν → 2 γ , and ν γ → ν γ , which are of astrophysical interest, are calculated both in the electroweak model and in the magnetic model when the ...
Euler-form actions and the vanishing of the cosmological constant
We investigate the conditions of the vanishing cosmological constant and the presence of gravity and vector gauge fields in a D -dimensional non-Abelian Kaluza-Klein theory based on a dimensionally continued ...
Upper limit on the magnetic moment of the neutrino
We have recalculated the processes e ν → e ν and e + e − → ν ¯ ν due to an assumed magnetic moment κ of the neutrino (correcting some errors in the previous calculations). Comparing the results with ...
