Bottom Quark
Linked via "strange quark (s)"
Discovery and Nomenclature
The bottom quark was first experimentally observed in 1977 by the $\text{E}288$ collaboration led by Leon Lederman at the Fermi National Accelerator Laboratory (Fermilab)/) [3]. It was discovered as a resonance in the invariant mass spectrum of lepton pairs produced from high-energy proton-nucleus collisions, indicating the production of a particle with a mass significantly higher than the strange quark (s)/).
Initially, the pa… -

Fundamental Properties
The bottom quark possesses several defining properties that distinguish it from lighter quarks. Its large mass means that it predominantly decays via the weak nuclear force into lighter quarks (primarily the down quark (d)/) or strange quark (s)/)) through the emission of a $\text{W}^\pm$ boson.
