On Teraelectronvolt Majorana Neutrinos
The issue of existence of Majorana neutrinos with masses of the order of TeV and substantial couplings is addressed. A general neutrino mass matrix Mν with both features is constructed, however, the form of Mν is constrained very much by severe relations among the elements of mD and MR submatrices of Mν . These general relations follow from the perturbative construction of the light neutrino ma...

متن کاملGravitational wave astronomy - astronomy of the 21st century
An enigmatic prediction of Einstein’s general theory of relativity are gravitational waves. With the observed decay in the orbit of the Hulse-Taylor binary pulsar agreeing within a fraction of a percent with the theoretically computed decay from Einstein’s theory the existence of gravitational waves was firmly established. Currently there is a worldwide effort to detect gravitational waves with...
