LHCf实验将于2007年安装在LHC对撞机上，向前方向距离ATLAS相互作用点±140m。 LHCf的目的是通过测量中性π介子衰变中产生的光子来精确测量接近0度的π介子产生截面。这种测量对于模拟极高能宇宙射线在大气中引起的流星雨至关重要。质心框架中可用的 14 TeV 能量实际上对应于实验室系统中 1017eV 的等效能量。本文重点介绍了所提出的实验以及我们期望从中得到的物理结果。
The LHCf experiment will be installed in 2007 on the LHC collider in the forward direction at ±140m from the ATLAS interaction point. The purpose of LHCf is to precisely measure the pion production cross section near zero degrees through the measurement of the photons produced in neutral pion decay. This measurement is crucial for the simulation of the showers induced in the atmosphere by very high energy cosmic rays; the 14 TeV energy available in the center of mass frame corresponds in fact to an equivalent energy of 1017eV in the laboratory system. The paper focus on the proposed experiment and on the physics results that we expect from it.
