These (GSI/Darmstadt) experiments, whose history, latest reconfirmations, and most recent data were presented in three opening sessions (Bokemeyer, Koenig), show a smooth background of positron (e+) production, as a function of e+ kinetic energy. Superimposed upon this background are four very sharp peaks, of narrow widths (~ 30 KeV) and of clear experimental significance (‘" 5 standard deviations). Most ofthese peaks correspond to sharp, essentially back-to-back electron-positron emission in the ions‘ center of mass. Following the approach of "supercritical" potential theory (SPT), where the total ionic charge unit Z satisfies Z > 137, it has been possible to provide a detailed and apparently correct understanding of the smooth e+ e- background; a coherent description of different facets of this approach, emphasizing the nature of the charged, supe | | 出版日期 | Book 1991 | | 关键词 | Potential; Renormalization group; electromagnetic field; field theory; gluon; heavy ion; ion; quantum chrom | | 版次 | 1 | | doi | https://doi.org/10.1007/978-1-4757-0441-9 | | isbn_softcover | 978-1-4757-0443-3 | | isbn_ebook | 978-1-4757-0441-9Series ISSN 0258-1221 | | issn_series | 0258-1221 | | copyright | Plenum Press, New York 1991 |
