Wigner表示的弦定域量子场

String-localized quantum fields from Wigner representations

Jens Mund, Bert Schroer, Jakob Yngvason

摘要:

与有限自旋或螺旋度的庞加莱群的通常表示相反,质量为零和无限自旋的维格纳表示与点状局域量子场不相容。我们在这里提出了一个与这些表示相关的量子场的构造,这些表示位于半无限的类空弦中。该结构是基于拉格朗日量子化领域以外的概念,具有进一步应用的潜力。

英文摘要:

In contrast to the usual representations of of the Poincaré group of finite spin or helicity the Wigner representations of mass zero and infinite spin are known to be incompatible with pointlike localized quantum fields. We present here a construction of quantum fields associated with these representations that are localized in semi-infinite, space-like strings. The construction is based on concepts outside the realm of Lagrangian quantization with the potential for further applications.
