| 1. | It is not uncommon to also replace strangeness by flavor hypercharge.
|
| 2. | This changes their weak hypercharge ( and weak isospin ).
|
| 3. | This changes their weak isospin ( and weak hypercharge ).
|
| 4. | The weak hypercharge ( ) of both components is.
|
| 5. | That's why sometimes it is usefull to replace strangeness with flavor hypercharge.
|
| 6. | Weak hypercharge, however, remains of practical use in various theories of the electroweak interaction.
|
| 7. | A sterile neutrino would have the same weak hypercharge, weak isospin, and mass as its antiparticle.
|
| 8. | Hypercharge in particle physics is a quantum number relating the strong interactions of the SU ( 3 ) model.
|
| 9. | Isospin is defined in the SU ( 2 ) model while the SU ( 3 ) model defines hypercharge.
|
| 10. | It is conserved ( only terms that are overall weak-hypercharge neutral are allowed in the Lagrangian ).
