论文摘要
我们研究了在d = 3-2 \ ep中的尺寸正则化框架中，在三维淬火量子电动力学中研究了无质量传播量的量规交联。假设淬灭扰动膨胀的有限性，即限制\ ep \至0的存在，我们声明，正好在d = 3中，所有奇数扰动系数（从第三阶开始）在任何仪表中都应为零。
We study the gauge-covariance of the massless fermion propagator in three-dimensional quenched Quantum Electrodynamics in the framework of dimensional regularization in d=3-2\ep. Assuming the finiteness of the quenched perturbative expansion, that is the existence of the limit \ep \to 0, we state that, exactly in d=3, all odd perturbative coefficients, starting with the third order one, should be zero in any gauge.
