quark's

This process differs from what is expected for the bottom quark's antiparticle, the anti-bottom quark, and thus the symmetry is broken.

Now if Hugh Hewitt had a scintilla- an iota- a quark's worth- of integrity, he'd admit this, and explain it.

This is both because the weight of a bottom quark means that high energy collisions are needed to produce it it's over 4GeV, compared to the up quark's 3MeV, and because these particles only live for a very short time before decaying.

Online March 10, the team reported additional evidence of the top quark's puzzling directional preference after examining the paths of quarks generated by a different set of particle interactions.

There's only about a 0.07 percent chance that the top quark's apparent directional preference is a fluke, Amidei notes.
