从高能和极小动量转移np弹性散射数据看新的轻粒子的界限

Bounds on new light particles from high-energy and very small momentum transfer np elastic scattering data

Yuri Kamyshkov, Jeffrey Tithof, Mikhail Vysotsky

摘要:

我们发现,自旋一个新的轻粒子交换强烈约束的高能量和小动量转移NP弹性散射数据的标量粒子的类似的约束是相当弱,而赝标量粒子没有边界可以设置。这些边界进行了比较,从低能n-Pb散射实验和从π 0和K+介子衰变的边界提取的边界。

英文摘要:

We found that spin-one new light particle exchanges are strongly bounded by high-energy and small momentum transfer np elastic scattering data; the analogous bound for a scalar particle is considerably weaker, while for a pseudoscalar particle no bounds can be set. These bounds are compared with the bounds extracted from low-energy n-Pb scattering experiments and from the bounds of pi0 and K+ meson decays.
