Probing nucleon strangeness in phi electroproduction
  We investigate $\phi$ meson electroproduction to probe the hidden strangeness content of the nucleon. We found that even a small amount of the $s\bar{s}$ admixture in the nucleon wavefunction can lead to a significant change in several double polarization asymmetries in $\phi$ electroproduction, which can be tested experimentally at current electron facilities.
