Interpretation of new evidence for free quarks

Taking the recent results of LaRue, Fairbank, and Phillips at face value and assuming the fractional charge observed on three out of nine niobium balls was due to quarks, it is concluded that these three balls contained at least three d-bar quarks and two u quarks on their surfaces. It is shown that this result is not inconsistent with the negative results of other quark searches provided that primordial quarks are predominantly positively charged, the u-d mass difference is less than the electron mass, and total confinement is invalid. A cosmological proof is given that primordial quarks must be positively charged
