Title:
Rafting for Solar Neutrinos
Explanation:
Where have all the neutrinos [ http://www.conknet.…] gone? A long time passing since this question was first asked (decades) as increasingly larger and more diverse detectors [ http://www.autodyna…] sensitive to neutrinos from our Sun [ http://www.maths.qm…] have found fewer than expected. But why? [ http://www.sns.ias.…] Above, scientists check the equipment surrounding a huge tank of extremely pure water [ http://geb.phys.was…] from the Super-Kamiokande [ http://geb.phys.was…] experiment in Japan, designed to detect colliding neutrinos [ http://pdg.lbl.gov/…]. Large detectors are needed because the neutrino [ http://astro.caltec…] is an elementary particle [ http://pdg.lbl.gov/…] that goes right through practically everything. Reasons for the lack of solar neutrinos [ http://www.sns.ias.…] may include a more complex theory for electroweak interactions [ http://pdg.lbl.gov/…] than currently in use. Future results from detectors [ http://dept.physics…] like Super-Kamiokande may help us know more.
