Neutrino Masses

Some articles on neutrinos, neutrino masses, neutrino, masses:

Spin (physics) - Magnetic Moments
... Neutrinos are both elementary and electrically neutral ... Model that takes into account non-zero neutrino masses predicts neutrino magnetic moments of where the μν are the neutrino magnetic moments, mν are the neutrino masses ... scale could, however, lead to significantly higher neutrino magnetic moments ...
Standard Model (mathematical Formulation) - Lagrangian Formalism - Mass Terms and The Higgs Mechanism - Neutrino Masses
... As previously mentioned, evidence shows neutrinos must have mass ... But within the standard model, the right-handed neutrino does not exist, so even with a Yukawa coupling neutrinos remain massless ... An obvious solution is to simply add a right-handed neutrino resulting in a Dirac mass term as usual ...
Super Nova - Current Models - Core Collapse
... by beta decay, photodisintegration and electron capture, which causes a burst of electron neutrinos ... As the density increases, neutrino emission is cut off as they become trapped in the core ... If the core mass is more than about 15 solar masses then neutron degeneracy is insufficient to stop the collapse and a black hole forms directly with no supernova explosion ...
Large Extra Dimension - Opponents' Views
... the Planck scale were only about 109 electron masses, which is 1,000 TeV ... The neutrinos are only massless because the dimension-five operator does not appear ... But neutrinos have a mass scale of approximately eV, which is 14 orders of magnitude smaller than the scale of the Higgs expectation value of 1 TeV ...
Grand Unified Theory - Neutrino Masses
... Since Majorana masses of the right-handed neutrino are forbidden by SO(10) symmetry, SO(10) GUTs predict the Majorana masses of right-handed ... GUTs, this scale tends to be larger than would be desirable to obtain realistic masses of the light, mostly left-handed neutrinos (see neutrino oscillation) via the seesaw mechanism ...

Famous quotes containing the word masses:

    It was so long since I’d seen masses of young men that I’d forgotten how much pleasanter men of between twenty and thirty were to be around with than older men. It isnt so true of women. When I was in my twenties I thought the grown adults I ran into were a disaster and now I know I was right.
    John Dos Passos (1896–1970)
