hi- i clicked on the sneutrino pair event posted at http://www-sldnt.slac.stanford.edu/nld/ and it looks very nice. however, in the accompanying diagram, charge doesn't seem to be conserved since it has posted sneutrino->e+Z~, where Z~->mu+mu-\chi_2, etc. also, the other snuetrino also doesn't seem to conserve charge. do you know what was really happening in the posted event? thanks, howie baer
