Download or read book Using K Decays as a Source of Tagged. Pi. °'s written by and published by . This book was released on 1982 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: It appears that using K/sup + -/ ..-->.. ..pi ... pi..° is a useful source of tagged ..pi..°'s to investigate the rare decays ..pi..° ..-->.. ee−, ..pi..° ..-->.. ..gamma gamma..approx., and ..pi..° ..-->.. ..nu.. anti ..nu ... Present accelerator intensities may be sufficient to study the first process, although a detailed experimental design may show that higher intensities are needed. Higher flux beams clearly are needed to achieve the best sensitivity to ..pi..° ..-->.. ..nu.. anti ..nu.. and ..pi..° ..-->.. ..gamma gamma..approx.
