“…AGN, if they produce measurable fluxes of neutrinos, would provide a range of very remote point sources. Measurements of neutrinos from a variety of distances (ideally with flavor ratios) would provide important information for testing neutrino properties at increas-ing L/E (distance/energy) [22,92,93,94,95,96,97,98,99,100].…”

Recent observations, particularly from the HESS Collaboration, have revealed rich Galactic populations of TeV gamma-ray sources, including a collection unseen in other wavelengths. Many of these gamma-ray spectra are well measured up to 10 TeV, where low statistics make observations by air Č erenkov telescopes difficult. To understand these mysterious sources, especially at much higher energies-where a cutoff should eventually appear -new techniques are needed. We point out the following: (1) For a number of sources, it is very likely that pions, and hence TeV neutrinos, are produced; (2) As a general point, neutrinos should be a better probe of the highest energies than gamma rays, due to increasing detector efficiency; and (3) For several specific sources, the detection prospects for km 3 neutrino telescopes are very good, 1-10 events/year, with low atmospheric neutrino background rates above reasonable energy thresholds. Such signal rates, as small as they may seem, will allow neutrino telescopes to powerfully discriminate between models for the Galactic TeV sources, with important consequences for our understanding of cosmic-ray production.

“…Indeed, neutrinoless double-beta decay proceeds only when neutrinos are massive Majorana particles, hence its observation would resolve the question [28]. It has been shown that the inclusion of the np pairing a e-mail: allaln@yahoo.com influences the neutrinoless double-beta decay rates significantly [9].…”

Abstract. The usual neutron-proton BCS wave function is simultaneously projected on both the good neutron and proton numbers using a discrete projection operator. The projected energy of the system is deduced as a limit of rapidly convergent sequence. It is numerically studied for the N = Z nuclei of which "experimental" pairing gaps may be deduced from the experimental odd-even mass differences. It then appears that the particle-number fluctuation effect is even more important than in the case of pairing between like-particles.PACS. 21.60.-n Nuclear structure models and methods -21.30.Fe Forces in hadronic systems and effective interactions
