论文摘要
我们证明，范式从将Deuton视为构成质子和中子的系统转变为将其视为一个伪向量系统，在该系统中我们观察到质子和中子，导致可能探测新的“不完整” P-state类似于光（LF（LF）（lf）（LF）上的类似于（lf）的p-state结构，它可以在极大的内部力量转移，可以在很大的能量转移中转移，并且可以在很大的能量转移。 Investigating the deuteron on the light-front, where the vacuum-fluctuations are suppressed, we found that this new structure, together with conventional S- and D- states, is a leading order in transferred energy of the reaction, thus it is not suppressed on the light-front.The incompleteness of the observed P-state results in a violation of angular condition which can happen only if deuteron contains non-nucleonic structures such as $δ$$δ$，$ n^*n $或隐藏的颜色组件。我们证明，“不完整” P园的实验可验证的特征是核子中核子LF动量分布的角各向异性，以及在Deuteron大型内部Momenta的S型和D波预测以外的张量极化强度的增强。
We demonstrate that a paradigm shift from considering the deuteron as a system of bound proton and neutron to considering it as a pseudo-vector system in which we observe proton and neutron, results in a possibility of probing a new "incomplete" P-state like structure on the light-front (LF), at extremely large internal momenta, which can be achieved in high energy transfer electro-disintegration of the deuteron. Investigating the deuteron on the light-front, where the vacuum-fluctuations are suppressed, we found that this new structure, together with conventional S- and D- states, is a leading order in transferred energy of the reaction, thus it is not suppressed on the light-front.The incompleteness of the observed P-state results in a violation of angular condition which can happen only if deuteron contains non-nucleonic structures such as $Δ$$Δ$, $N^*N$ or hidden color components. We demonstrate that experimentally verifiable signatures of "incomplete" P-states are angular anisotropy of LF momentum distribution of the nucleon in the deuteron as well as an enhancement of the tensor polarization strength beyond the S- and D- wave predictions at large internal momenta in the deuteron.
