The Bose-Einstein Correlations and the strong coupling constant at low energies
It is shown that , the strong coupling constant, can be
determined in the non-perturbative regime from Bose-Einstein correlations
(BEC). The obtained is in agreement with the prescriptions dealt
with in the Analytic Perturbative Theory approach. It also extrapolates
smoothly to the standard perturbative at higher energies. Our
results indicate that BEC dimension can be considered as an alternative
approach to the short range measure between hadrons.Comment: 7 pages, 4 figure
Improved Limit on theta_{13} and Implications for Neutrino Masses in Neutrino-less Double Beta Decay and Cosmology
We analyze the impact of a measurement, or of an improved bound, on
theta_{13} for the determination of the effective neutrino mass in
neutrino-less double beta decay and cosmology. In particular, we discuss how an
improved limit on (or a specific value of) theta_{13} can influence the
determination of the neutrino mass spectrum via neutrino-less double beta
decay. We also discuss the interplay with improved cosmological neutrino mass
searches.Comment: 22 pages, 5 figures. Minor corrections, matches version in PR
