Abstract
We report new measurements of the parity-violating asymmetry APV in elastic scattering of 3 GeV electrons off hydrogen and He4 targets with ⟨θlab⟩≈6.0°. The He4 result is APV=(+6.40±0.23(stat)±0.12(syst))×10−6. The hydrogen result is APV=(−1.58±0.12(stat)±0.04(syst))×10−6. These results significantly improve constraints on the electric and magnetic strange form factors GEs and GMs. We extract GEs=0.002±0.014±0.007 at ⟨Q2⟩=0.077 GeV2, and GEs+0.09GMs=0.007±0.011±0.006 at ⟨Q2⟩=0.109 GeV2, providing new limits on the role of strange quarks in the nucleon charge and magnetization distributions.
نُقدّم قياسات جديدة للا تناظر انتهاك التكافؤ APV في الاستطارة المرنة لإلكترونات بطاقة 3 GeV على أهداف من الهيدروجين وHe4 بزاوية ⟨θlab⟩≈6.0°. وبلغت نتيجة He4 القيمة APV=(+6.40±0.23(stat)±0.12(syst))×10−6، في حين بلغت نتيجة الهيدروجين APV=(−1.58±0.12(stat)±0.04(syst))×10−6. وتُحسّن هذه النتائج بشكل ملحوظ القيود المفروضة على عوامل الشكل الغريبة الكهربائية والمغناطيسية GEs وGMs. ونستخلص أن GEs=0.002±0.014±0.007 عند ⟨Q2⟩=0.077 GeV2، وGEs+0.09GMs=0.007±0.011±0.006 عند ⟨Q2⟩=0.109 GeV2، مما يوفر حدودًا جديدة لدور الكواركات الغريبة في توزيعات الشحنة والمغنطة داخل النيوكليون.
3 GeV elektronların hidrojen ve He4 hedeflerinden ⟨θlab⟩≈6.0° açısındaki esnek saçılmasında pariteyi bozan asimetri APV'nin yeni ölçümlerini sunuyoruz. He4 sonucu APV=(+6.40±0.23(istat)±0.12(sist))×10−6'dır. Hidrojen sonucu ise APV=(−1.58±0.12(istat)±0.04(sist))×10−6'dır. Bu sonuçlar; elektrik ve manyetik tuhaf form faktörleri GEs ve GMs üzerindeki kısıtları önemli ölçüde iyileştirmektedir. ⟨Q2⟩=0.077 GeV2'de GEs=0.002±0.014±0.007 ve ⟨Q2⟩=0.109 GeV2'de GEs+0.09GMs=0.007±0.011±0.006 değerlerini elde ederek, tuhaf kuarkların nükleon yük ve manyetizasyon dağılımlarındaki rolüne ilişkin yeni sınırlar sunmaktayız.
我们报道了在 ⟨θlab⟩≈6.0° 下，3 GeV 电子在氢靶和 He4 靶上弹性散射的宇称破坏不对称度 APV 的最新测量结果。He4 的测量结果为 APV=(+6.40±0.23(stat)±0.12(syst))×10−6。氢的测量结果为 APV=(−1.58±0.12(stat)±0.04(syst))×10−6。这些结果显著改善了对奇异电形状因子 GEs 和奇异磁形状因子 GMs 的约束。我们在 ⟨Q2⟩=0.077 GeV2 处提取出 GEs=0.002±0.014±0.007，并在 ⟨Q2⟩=0.109 GeV2 处提取出 GEs+0.09GMs=0.007±0.011±0.006，为奇异夸克在核子电荷及磁化分布中的作用提供了新的限制。
