1. Where " y " b is the bottom quark Yukawa coupling. 2. At higher masses, the vector mesons include charm and bottom quarks in their structure. 3. This was the first discovery of the bottom quark . 4. A third generation leptoquark, for example, might decay into a bottom quark and a tau lepton. 5. The existance of the top and bottom quarks is necessitated by the symmetry in the Standard Model. 6. The bottom quark can decay into either an up quark or charm quark via the weak interaction. 7. Among his achievements are the discovery of the muon neutrino in 1962 and the bottom quark in 1977. 8. It was discovered by quark generations namely, a down quark, a strange quark, and a bottom quark . 9. Some years later a further building block was discovered _ one of the family's two quarks, the bottom quark . 10. Strange quarks also bind with the heavier charm and bottom quarks which also like to bind with each other.
