In this illustration, two protons collide at high energy, producing a Higgs boson that instantly decays, producing two tau particles. The rest of the energy from the collision sprays outward in two jets (pink cones). Measuring the angle between these jets could reveal whether or not the Higgs is involved in charge-parity (CP) violation, which says that nature treats a particle and its oppositely charged antiparticle differently. A SLAC researcher and his colleagues propose such an experiment in a recent paper in Physical Review D.
