在快速范围内中性介子的包括产生速率大于2010年初在质子-质子碰撞操作期间由大型强子对撞机（LHCf）实验测量的。本文给出了中性介子的横向动量谱。来自两个独立的LHCf探测器的光谱彼此一致，并作为数据的交叉检查。横向动量谱还与几个强子相互作用模型的预测结果进行了比较，这些模型通常用于高能粒子物理和模拟超高能宇宙射线阵雨。
The inclusive production rate of neutral pions in the rapidity range greater thanhas been measured by the Large Hadron Collider forward (LHCf) experiment duringproton-proton collision operation in early 2010. This paper presents the transverse momentum spectra of the neutral pions. The spectra from two independent LHCf detectors are consistent with each other and serve as a cross-check of the data. The transverse momentum spectra are also compared with the predictions of several hadronic interaction models that are often used for high-energy particle physics and for modeling ultrahigh-energy cosmic ray showers.
