The Italian government has scrapped plans to build a particle accelerator known as SuperB in the outskirts of Rome after a new study calculated its total cost to be about ?1 billion??some ?350 million more than previously estimated. SuperB was to have been built on the campus of the University of Rome Tor Vergata by an international collaboration of scientists. It would have collided beams of electrons and positrons to produce B mesons and other exotic particles. ??????????????????????????????????????????????B???????????????????з?????????????????10??????????????????3.5????????????B?????????????????????Rome Tor Vergata????????????????????????????????????????????????????????????B?????????????????? The Italian government had promised ?250 million; other countries, including France and Russia, said they might pay a share of the costs; and the United States had agreed to donate parts from a decommissioned accelerator at the SLAC laboratory in California. But the growing price tag and an unbridgeable funding gap sank the project. The Italian government has invited Italy??s National Institute of Nuclear Physics to pitch proposals for new projects that could be funded with the ?250 million it had originally promised. ??????????????????2.5???????????????????????????????????????????е???????????????????????????????SLAC???????????????????????????????????????????????????????????????????????????????????????????????????????????????о???????????Щ?????????????Щ?????????????????????2.5????????? *************************************************************** Science??????????????????????????????????????????????????????????????Science?????????????????????????лл??
