In addition to the beauty quark (the "b" in "LHCb"), HEP is interested in the charmed quark.
Other important properties are the couplings to other elementary particles such as the beauty quark, charm quark, muon and electron, with their SM branching ratios proportional to the squares of the fermion masses.
Theory says that a beauty quark should decay into a charm quark.
