bottom quark การใช้
- Where " y " b is the bottom quark Yukawa coupling.
- At higher masses, the vector mesons include charm and bottom quarks in their structure.
- This was the first discovery of the bottom quark.
- A third generation leptoquark, for example, might decay into a bottom quark and a tau lepton.
- The existance of the top and bottom quarks is necessitated by the symmetry in the Standard Model.
- The bottom quark can decay into either an up quark or charm quark via the weak interaction.
- Among his achievements are the discovery of the muon neutrino in 1962 and the bottom quark in 1977.
- It was discovered by quark generations namely, a down quark, a strange quark, and a bottom quark.
- Some years later a further building block was discovered _ one of the family's two quarks, the bottom quark.
- Strange quarks also bind with the heavier charm and bottom quarks which also like to bind with each other.
- However a contains one up, one strange, and one bottom quark, while a contains one up and two bottom quarks.
- However a contains one up, one strange, and one bottom quark, while a contains one up and two bottom quarks.
- The heavier scalar mesons containing charm and / or bottom quarks all occur well over 2 GeV / c 2.
- Each B meson has an antiparticle that is composed of a bottom quark and an charm antiquark ( ) respectively.
- So, since the strange and bottom quarks have a negative charge, they have flavor quantum numbers equal to " 1.
- This allows us to measure, for example, bottom quarks which decay into a relatively long-lived B-meson through " topological " cuts.
- Bottom quarks have ( by convention ) a bottomness of & minus; 1 while bottom antiquarks have a bottomness of + 1.
- It was first observed by the BaBar experiment at SLAC in 2008, and is the lightest particle containing a bottom and anti-bottom quark.
- By the time it can interact strongly it has already decayed to another flavour of quark ( usually to a bottom quark ).
- And while other producers have been busy taking meetings, Lederman has been discovering the muon neutrino, the neutral K-meson and the bottom quark.
