中微子振荡的场论描述的协变非对称波包
Covariant asymmetric wave packet for a field-theoretical description of neutrino oscillations
摘要：
考虑了一类相对论协变波包模型，它可以作为量子场论形式中描述中微子味振荡现象的渐近自由进出态。我们证明了新的“非对称”波包（AWP）是一个合适的替代更方便的“对称”波包，如所谓的相对论高斯包（RGP）广泛用于基于QFT的方法中微子振荡。我们表明，RGP是AWP的一个特殊情况下，虽然这些模型的许多属性几乎是相同的准稳定制度。我们讨论了AWP区别于RGP的一些特征。
英文摘要：
We consider a class of models for the relativistic covariant wave packets which can be used as asymptotically free in and out states in the quantum field theoretical formalisms for description of the neutrino flavor oscillation phenomenon. We demonstrate that the new "asymmetric" wave packet (AWP) is an appropriate alternative for the more convenient "symmetric" wave packets, like the so-called relativistic Gaussian packet (RGP) widely used in the QFT-based approaches to neutrino oscillations. We show that RGP is not a particular case of AWP, although many properties of these models are almost identical in the quasistable regime. We discuss some features of AWP distinguishing it from RGP.
