| Data on the quark and lepton masses and on their superpartner masses may provide major clues to teach us about string theory. |
|
| Scientists became alerted to the existence of the third, tau neutrino in 1977 with the discovery of the tau lepton. |
|
| In any reaction between particles, anti or normal, the baryon and lepton numbers must be conserved. |
|
| It is also possible to compute the average baryon and lepton numbers at finite temperatures and in the relativistic domain. |
|
| You are right that you could suppress such processes by requiring the separate generation lepton numbers to be conserved. |
|
| When you add the appropriate baryon and lepton numbers and know the beginning charge of both particles, all three of these numbers must be equal before and after the reaction. |
|
| The observation of the following two decay processes leads to the conclusion that there is a separate lepton number for muons which must also be conserved. |
|
| The Standard Model of particle physics well describes all the current quark and lepton data. |
|
| Discovered in 1935 by CarlAnderson, the mu-meson is now known to be a type of lepton, a particle similar to the ordinary electron, but more than two hundred times as heavy. |
|
| The borrowed energy is then reabsorbed by the receiving quark or lepton. |
|
| At lower energies, the symmetry is broken, and the three quark and lepton generations will split off in the way that is seen in nature. Technicolour, according to its proponents, can also explain the hierarchy problem. |
|
| In the advanced stages, the shoulders of the lepton are shorter as well. |
|
| There is a third, heavier type of charged lepton, called the tau. |
|
| The W particles play a crucial role in interactions that turn one flavour of quark or lepton into another, as in the beta decay of a neutron, where a down quark turns into an up quark to form a proton. |
|
| Furthermore, there might have been more than one mint in that remote Province of the Empire, and rather unskilful for coins of very little value just as the lepton. |
|
| The EW isospin states define the flavor of the fundamental lepton and quark states. |
|
| Each lepton group represents the binary rotational symmetries of familiar 3-D regular polyhedrons, the tetrahedron, the octahedron, and the icosahedron. |
|
| Until now, experimenters could find only hints of tau neutrinos' presence, such as energy and momentum missing from decays of the particle called a tau lepton. |
|
| Along with the electron and muon, the tau particle and three varieties of neutrinos are now firmly established as members of the lepton group of subatomic particles. |
|
| The Lepton IC was specifically designed for global operation, allowing for a tag that can write and read around the world. |
|
|
|
| A HORSE-loving couple from Lepton are selling their Wakeeld Road home ready for a move to begin a new life in Southern Ireland. |
|
| The smart blue pullovers with a traditional shirt and tie were chosen by the children at Lepton C of E Junior and Infant School and their parents. |
