论文摘要
由于无法隔离夸克和古怪，因此在其最低能量状态下的复合$ q \ bar q $系统的固有运动主要位于1+1个维度上，例如在其两端的夸克和古夸克的开放式琴弦中。因此，我们研究了QCD中的开放字符串$ q \ b q $系统的最低能量状态，并在1+1个维度中进行QED。我们表明，$π^0，η$和$η'$可以被充分描述为打开字符串$ q \ bar q $ qcd梅森。通过将Quark和Antiquark与QED相互作用相互作用的$ Q \ bar Q $ Q $ QED领域，我们找到一个开放的弦线等iSoscalar $ i（j^π）$ = $ 0（0^ - 0^ - ）$ QED MESON State在17.9 $ \ pm $ $ 1.5 mev and isovector $ 1.5 meev and Isovector $ _（j^$ = $ 1（j^pe）状态36.4 $ \ pm $ 3.8 mev。等轴和等异分剂的预测质量最近观察到的假设X17和E38颗粒的质量接近，使其成为这些颗粒的良好候选者。 QED介子的衰减产物可能显示为与高能强化强化强生产的异常软光子现象中的多余$ E^+e^ - $和$γγ$对，在高能量的强子Proton碰撞和$ e^+$ - $ - $ - $ - $ e^ - $ $ annihihihiliations中。多余的$ e^+e^ - $和$γγ$对的不变质量的测量将为存在的开放字符串$ q \ bar q $ qed ersons提供测试。预计引力QED介子的组装将发射电子峰值和/或伽马射线，并且它们的衰变能量和寿命将通过其重力结合能来修饰。因此，一个自我磨碎的等iSoscalar Qed梅森大会，其质量$ $ m $和半径$ r $满足$（m/m_ \ odot）/（r/r_ \ odot）\ gtrsim 4.71 \ times 10^5 $不会产生良好的primand candicationd primical damport deackication damportiald targe damportiald。
As a quark and an antiquark cannot be isolated, the intrinsic motion of a composite $q \bar q$ system in its lowest-energy states lies predominantly in 1+1 dimensions, as in an open string with the quark and the antiquark at its two ends. Accordingly, we study the lowest-energy states of an open string $q\bar q$ system in QCD and QED in 1+1 dimensions. We show that $π^0, η$, and $η'$ can be adequately described as open string $q\bar q$ QCD mesons. By extrapolating into the $q\bar q$ QED sector in which a quark and an antiquark interact with the QED interaction, we find an open string isoscalar $I(J^π)$=$0(0^-)$ QED meson state at 17.9$\pm$1.5 MeV and an isovector $(I(J^π)$=$1(0^-), I_3$=0) QED meson state at 36.4$\pm$3.8 MeV. The predicted masses of the isoscalar and isovector QED mesons are close to the masses of the hypothetical X17 and E38 particles observed recently, making them good candidates for these particles. The decay products of QED mesons may show up as excess $e^+e^-$ and $γγ$ pairs in the anomalous soft photon phenomenon associated with hadron productions in high-energy hadron-proton collisions and $e^+$-$e^-$ annihilations. Measurements of the invariant masses of excess $e^+e^-$ and $γγ$ pairs will provide tests for the existence of the open string $q\bar q$ QED mesons. An assembly of gravitating QED mesons are expected to emit electron-positron pairs and/or gamma rays and their decay energies and lifetimes will be modified by their gravitational binding energies. Consequently, a self-gravitating isoscalar QED meson assembly whose mass $M$ and radius $R$ satisfy $(M/M_\odot)/(R/R_\odot) \gtrsim 4.71 \times 10^5$ will not produce electron-positron pairs nor gamma rays and may be a good candidate for the primordial dark matter.
