It was pointed out by Wilson [2], that in many field theories it is possible to assign a dimension d to every fundamental field, which proves to be a conserved quantum number as far as the most singular term of an operator product expansion at small distances ((x-y) +a) is con- JJ cerned++. Later it was shown, at the canonical level, that in many field theories the dimension of a field seems to be a c:pod quantum number even in the terms less singular at small (x-y) , as long as they all belong to the strongest l light cone singularity (i. e. (x-y)2+a) [3]. The assumption that this type of scale invariance on the light cone be present in the operator product ex- pansion of two electromagnetic currents has provided us with a rather natural explanation of the observed scaling phenomena. We should like to mention, however, that this ex- planation cannot account for the precocity with which scaling is being observed experimentally in energy regions, in which r | | 出版日期 | Conference proceedings 1972 | | 關(guān)鍵詞 | Elementarteilchen; Particle Physics; elementary particle | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-7091-4034-5 | | isbn_softcover | 978-3-7091-4036-9 | | isbn_ebook | 978-3-7091-4034-5 | | copyright | Springer-Verlag Wien 1972 |
