Do Neutrinos Have Mass Only within Matter?

We look at the possibility that appreciable neutrino masses and flavor mixing occur only within material media, driven by an interaction between leptons and a very light scalar particle. Limits are placed on the scalar particle mass and coupling constants from a number of experimental and astrophysical considerations. 1.Introduction. The recent results on atmospheric neutrinos [1]-[4] offer a p...

Atomic Compton Profiles within different exchange-only theories

The Impulse Compton Profiles (CP’s) J(q) and the 〈pn〉− expectation values for some inert gas atoms(He-Kr) are computed and compared within the Harbola-Sahni (HS), Hartree-Fock (HF) theories and a Self Interaction Corrected (SIC) density functional model. The Compton profiles for excited states of Helium atom are also calculated. While the calculated CP’s are found to generally agree, they diffe...

hapax legomenon in the qur’an: an analysis of the words that occurs only once within the text

hapax legomenon (pl. hapax legomena; sometimes abbreviated to hapax, pl. hapaxes), is a word that occurs only once within a context, either in the written record of an entire language, in the works of an author, or in a single text. the related terms, dis legomenon, tris legomenon, and tetrakis legomenon respectively refer to double, triple, or quadruple occurrences, but are far less commonly u...
