    Up and Down Quarks Favored over Strange Ones

    August 31, 2015, Categories  Physics

    Researchers added extra energy to the proton to produce a pair of quarks, which then yielded new particles. In this illustration, a strange/anti-strange quark pair (s and ?) yields a Lambda (^) hyperon and Kaon (K+ meson). The researchers found that strange/anti-strange quark pairs were produced about one-third as often as pairs of up/anti-up (u) and down/anti-down (d) quarks. Credit: Image courtesy of Jefferson Lab

    A suppression of strange quark production vs up and down quark production had previously been noted, and for the 1st time, the result has been verified when a single pair is produced.

    Protons are composed of 3 quarks – 2 up quarks and 1 down quark bound together by the “strong force” – 1 of the 4 natural forces in our universe...
