DESCRIPTION:Speakers: Mikhail Gorshteyn (Institut fur Kernphysik\, Johanne
 s Gutenberg-Universitat)\n\nNeutrino-mediated long range parity-violating 
 electron-nucleus interactions\nRecently\, it has been claimed that hadroni
 c weak charges might receive unexpectedly large — up to 1% (!) —  cor
 rections due to neutrino-induced long range parity-violating potentials\, 
 arising at the one-loop level in the Standard Model. I show that these cla
 ims are unsubstantiated as they are based on a neglect of the finite nucle
 ar size. Once the latter is correctly accounted for\, these electroweak co
 rrections acquire their natural size\, O(GF/R2)\, with GF the Fermi consta
 nt and R the nuclear radius. Numerically\, it amounts to mere 1e-8 or less
  correction to the hadronic weak charges\, making them negligible.  \n\nh
