标题： Particle Production Measurements using the MIPP Detector at Fermilab

摘要： 主注入器粒子产生（MIPP）实验是费米实验室的一个固定靶强子产生实验。 它测量主注入器提供的120 GeV/c初级质子与次级束流的相互作用，这些次级束流包括5到90 GeV/c的$\pi^{\pm}, \rm{K}^{\pm}$、p和$\bar{\rm{p}}$，在包含H、Be、C、Bi和U的核靶上进行，并且还包括使用NuMI靶的专用运行。 MIPP是一个高接受度的谱仪，利用时间投影室（TPC）、飞行时间（ToF）、多单元切连科夫（CKOV）、环成像切连科夫（RICH）探测器以及中子量能器提供优异的带电粒子识别能力。 我们展示了58和85 GeV/c p-H相互作用的非弹性截面测量结果，以及58和120 GeV/c p-C相互作用的非弹性截面测量结果。 描述了一种新方法，利用KNO标度来考虑相互作用触发中的低多重性效率问题。 还展示了作为多重性函数的非弹性截面。 MIPP数据与蒙特卡罗预测和以前的测量结果进行了比较。 我们还描述了一种识别带电粒子（$\pi^{\pm}/\rm{p}/\bar{\rm{p}}$等）的算法，并展示了120 GeV/c质子与碳靶相互作用产生的带电介子和K介子谱。 显示英文摘要

摘要： The Main Injector Particle Production (MIPP) experiment is a fixed target hadron production experiment at Fermilab. It measures particle production in interactions of 120 GeV/c primary protons from the Main Injector and secondary beams of $\pi^{\pm}, \rm{K}^{\pm}$, p and $\bar{\rm{p}}$ from 5 to 90 GeV/c on nuclear targets which include H, Be, C, Bi and U, and a dedicated run with the NuMI target. MIPP is a high acceptance spectrometer which provides excellent charged particle identification using Time Projection Chamber (TPC), Time of Flight (ToF), multicell Cherenkov (CKOV), Ring Imaging Cherenkov (RICH) detectors, and Calorimeter for neutrons. We present inelastic cross section measurements for 58 and 85 GeV/c p-H interactions, and 58 and 120 GeV/c p-C interactions. A new method is described to account for the low multiplicity inefficiencies in the interaction trigger using KNO scaling. Inelastic cross sections as a function of multiplicity are also presented. The MIPP data are compared with the Monte Carlo predictions and previous measurements. We also describe an algorithm to identify charged particles ($\pi^{\pm}/\rm{p}/\bar{\rm{p}}$ etc.), and present the charged pion and kaon spectra from the interactions of 120 GeV/c protons with carbon target.
