DPMJET的魅力生产

Charm Production in DPMJET

Patrick Berghaus, Teresa Montaruli, Johannes Ranft

摘要:

在这项工作中,粲生产的{ \sc dpmjet}强子喷流模拟实验数据进行了比较。由于{ \sc dpmjet}的主要应用是模拟宇宙射线诱导的空气簇射,因此已使用CORSIKA模拟包中集成的代码版本进行比较。在必要时,已作出调整,以改善模拟和数据之间的一致性。随着新的μ子/中微子探测器的可用性,结合了大的基准体积与大量的屏蔽,从宇宙射线相互作用的瞬发μ子和中微子的调查将是可行的第一次。此外,以上$\gtrsim 100$ TeV的粲粒子衰变成为弥漫的地外中微子通量搜索的主导背景。因此,需要一种可靠的方法来模拟高能质子-核子相互作用中的粲产生。

英文摘要:

In this work, charm production in the {\sc dpmjet} hadronic jet simulation is compared to experimental data. Since the major application of {\sc dpmjet} is the simulation of cosmic ray-induced air showers, the version of the code integrated in the CORSIKA simulation package has been used for the comparison. Wherever necessary, adjustments have been made to improve agreement between simulation and data. With the availability of new muon/neutrino detectors that combine a large fiducial volume with large amounts of shielding, investigation of prompt muons and neutrinos from cosmic ray interactions will be feasible for the first time. Furthermore, above $\gtrsim 100$ TeV charmed particle decay becomes the dominant background for diffuse extraterrestrial neutrino flux searches. A reliable method to simulate charm production in high-energy proton-nucleon interactions is therefore required.
