对约17和约38 MeV异常粒子的QED介子描述

QED meson description of the anomalous particles at ~17 and ~38 MeV

Cheuk-Yin Wong

AI总结:

该研究将Schwinger禁闭机制推广到轻夸克,用(1+1)维QED/QCD介子解释物理介子质量,并预言约17 MeV和38 MeV的QED介子,可关联X17、E38及异常软光子观测。

摘要:

Schwinger禁闭机制规定,在(1+1)维Abelian QED相互作用中,无质量费米子与无质量反费米子会被禁闭为一个有质量玻色子。如果我们将轻夸克近似为无质量,并把Schwinger禁闭机制应用于夸克,就可以推断,在(1+1)维中通过Abelian QED相互作用发生作用的轻夸克和轻反夸克会被禁闭为一个QED介子。类似地,在准Abelian近似下,通过QCD相互作用发生作用的轻夸克和轻反夸克将在(1+1)维中被禁闭为一个QCD介子。当适当考虑通量管半径时,(1+1)维中的QED和QCD介子可以表示(3+1)维中的物理介子。这样一种理论能够合理描述π⁰、η和η′的质量,而将其外推到未知的QED区段会得到一个约17 MeV的同位旋标量QED介子和一个约38 MeV的同位旋矢量QED介子。对异常软光子、假想X17粒子和假想E38粒子的观测,为QED介子可能存在提供了有希望的证据。在有待进一步确认的情况下,它们对夸克的性质及其相互作用具有重要意义。

英文摘要:

The Schwinger confinement mechanism stipulates that a massless fermion and a massless antifermion are confined as a massive boson when they interact in the Abelian QED interaction in (1+1)D. If we approximate light quarks as massless and apply the Schwinger confinement mechanism to quarks, we can infer that a light quark and a light antiquark interacting in the Abelian QED interaction are confined as a QED meson in (1+1)D. Similarly, a light quark and a light antiquark interacting in the QCD interaction in the quasi-Abelian approximation will be confined as a QCD meson in (1+1)D. The QED and QCD mesons in (1+1)D can represent physical mesons in (3+1)D when the flux tube radius is properly taken into account. Such a theory leads to a reasonable description of the masses of $π^0, η$, and $ η'$, and its extrapolation to the unknown QED sector yields an isoscalar QED meson at about 17 MeV and an isovector QED meson at about 38 MeV. The observations of the anomalous soft photons, the hypothetical X17 particle, and the hypothetical E38 particle bear promising evidence for the possible existence of the QED mesons. Pending further confirmation, they hold important implications on the properties on the quarks and their interactions.
