来自粲的中微子:在LHC和大气中的前向产生

Neutrinos from charm: forward production at the LHC and in the atmosphere

Yu Seon Jeong, Weidong Bai, Milind Diwan, Maria Vittoria Garzelli, Fnu Karan Kumar, Mary Hall Reno

摘要:

大气中瞬发中微子通量的理论预测有很大的不确定性与粲强子的产生有关,到目前为止,粲强子是大气中瞬发中微子的主要来源。宇宙射线的通量,其陡降的能谱,在评估高能大气中微子通量时,对粲的前向产生起着重要作用。欧洲核子研究中心目前的LHCb实验限制了与瞬发大气中微子通量相关的运动学区域的魅力产生。拟议的向前物理设施具有额外的能力来检测大型强子对撞机向前魅力产生的中微子通量。我们讨论了当前和计划中的实验对高能大气中微子通量理论预测发展的影响。

英文摘要:

Theoretical predictions of the prompt atmospheric neutrino flux have large uncertainties associated with charm hadron production, by far the dominant source of prompt neutrinos in the atmosphere. The flux of cosmic rays, with its steeply falling energy spectrum, weights the forward production of charm in the evaluation of the atmospheric neutrino flux at high energies. The current LHCb experiment at CERN constrains charm production in kinematic regions relevant to the prompt atmospheric neutrino flux. The proposed Forward Physics Facility has additional capabilities to detect neutrino fluxes from forward charm production at the LHC. We discuss the implications of the current and planned experiments on the development of theoretical predictions of the high energy atmospheric neutrino flux.
