LOCALITY OF THE STRANGE SEA IN THE NUCLEON

We introduce the concept of ''locality'' for the strange sea in the nu cleon, which measures the proximity of the strange and anti-strange qu arks in the momentum and coordinate spaces. The CCFR data for the stra nge and anti-strange distributions imply a ''local'' strange sea in mo mentum space, which is unexpected in QCD and is at variance with the s imple meson-cloud model where the strangeness is generated from the vi rtual transition of the nucleon to a hyperon plus a kaon. We present a simple model to interpret the CCFR data and to correlate momentum and coordinate space locality, yielding an upper bound of 0.005 fm(2) on the strange radius. We also discuss the significance of locality for o ther charge-conjugation-odd observables.
