At present, there is no major convincing inner space related experimental evidence against the standard model. The neutrino oscillation phenomena can be considered part of it by including a singlet ?eld in the spectrum. Only the outer space - servations on matter asymmetry, dark matter, and dark energy hint at the phenomenological need for an extension; however, there has been theoretical need for almost three decades, chie?y because of the gauge hierarchy problem in the standard model. Thus, it seems that going beyond the standard model hinges on the des- ability of resolving the hierarchy problem. At the ?eld theory level, it is fair to say that the hierarchy problem is not as desperate as the nonrenormalizab- ity problem present in the old V–A theory of weak interactions on the road to the standard model. An extension beyond the standard model can easily be ruled out as witnessed in the case of technicolor. However, a consistent framework with supersymmetry for a resolution of t | | 出版日期 | Book 20061st edition | | 关键词 | Lepton; Quark; chirality; compactification; orbifolds; superstrings; supersymmetry | | 版次 | 1 | | doi | https://doi.org/10.1007/b11681670 | | isbn_ebook | 978-3-540-32764-6Series ISSN 0075-8450 Series E-ISSN 1616-6361 | | issn_series | 0075-8450 | | copyright | Springer-Verlag Berlin Heidelberg 2006 |
