Physicists have confirmed a new mismatch between matter and antimatter 

Charge-parity violation occurs in a class of particles called baryons 

An illustration shows two protons colliding and producing another particle, which decays to create particle tracks.

Two protons (indicated with p’s) collide at the LHCb experiment, producing a lambda-b baryon comprised of three quarks — dubbed up (u), down (d) and bottom (b) — that decays into various other particles (colored lines).

There’s a newfound mismatch between matter and antimatter.
