Data for: Model-independent bounds on light pseudoscalars from rare B-meson decays

The file contains a ROOT Tree of the momenta of B^0, B_S^0, and B^+ and their anti-particles, produced after 400 GeV proton beam interactions onto a fixed proton target. The z component is along the beam line.

该文件包含一棵ROOT树（ROOT Tree），存储了400GeV质子束与固定质子靶发生相互作用后产生的B⁰、B_s⁰、B⁺介子及其反粒子的动量数据。其中各粒子动量的z分量沿束流轴线方向。
