Review of Short Phrases and Links|
This Review contains major "Neutrino Masses"- related terms, short phrases and links grouped together in the form of Encyclopedia article.
- Because neutrino masses are less than a few electron-Volts, neutrinos can only account for a small fraction of the dark matter that permeates the Universe.
- Under the Standard Model, a massless neutrino cannot oscillate, so this observation implied the existence of non-zero neutrino masses.
- This implied the existence of non-zero neutrino masses since massless particles travel at the speed of light and so do not experience the passage of time.
- Answering these questions requires precision measurements of the neutrino masses and mixings.
- The Majoron is predicted to understand neutrino masses by the seesaw mechanism.
- We consider the seesaw mechanism of neutrino mass generation in the light of our present knowledge of the neutrino masses and mixing.
- These indicate that the sum of the neutrino masses must be less than 0.3 electronvolt (Goobar, 2006).
- The model contains 19 free parameters, such as particle masses, which must be determined experimentally (plus another 10 for neutrino masses).
- In fact, the size of the neutrino masses is consistent with expectations from unified theories that require the new particles for the unification itself.
- The mechanism is commonly seen in grand unification theory, and in particular in theories of neutrino masses and neutrino oscillation.
- So far, the question of neutrino masses cannot be decided based on measurements of the neutrino speed.
- By combining this with information from previous measurements, it is possible to set an upper limit on the sum of the known neutrino masses.
- This is natural in certain grand unified theories, and if new physics appears at about 10 16 GeV, the neutrino masses are of the right order of magnitude.
- There, the exchange of supersymmetric particles such as squarks and sleptons can break the lepton number and lead to neutrino masses.
- CP violation, neutrino masses, fermion nonconservation, and possible extensions of the Standard Model.
- The standard model of particle physics, CP violation, the CKM matrix and the strong CP problem Neutrino masses, CPT invariance and tests of CPT violation.
- One important non-collider effort is the determination of the neutrino masses since these masses may arise from neutrinos mixing with very heavy particles.
- Neutrinos have opened a surprising new window on the physics of lepton generations, since neutrino masses are not necessary in the Standard Model.
