New data from ultra high-speed proton collisions at Europe's Large Hadron Collider (LHC) showed the bottom quark, also known as the 'beauty quark' behaves as predicted by the Standard Model.
The findings are reported in the journal Nature Physics.

In the Standard Model (SM) of particle physics, the decay of one quark to another by the emission of a virtual W boson is described by the 3 × 3 unitary Cabibbo–Kobayashi–Maskawa (CKM) matrix. This matrix arises from the coupling of the quarks to the Higgs boson. Although the SM does not predict the values of the four free parameters of the CKM matrix, the measurements of these parameters in different processes should be consistent with each other. If they are not, it is a sign of physics beyond the SM. In global fits combining all available measurements, the sensitivity of the overall consistency check is limited by the precision in the measurements of the magnitude and phase of the matrix element Vub, which describes the transition of a b quark to a u quark.
