Thanks to its multi-TeV LHC proton and lead beams, the LHC complex allows one to perform the most energetic fixed-target experiments ever and to study with high precision pp, pd and pA collisions at sqrt(s_NN) = 115 GeV and Pbp and PbA collisions at sqrt(s_NN) = 72 GeV. We present a selection of feasibility studies for the production of quarkonia, open heavy-flavor mesons as well as light-flavor hadrons in pA and PbA collisions using the LHCb and ALICE detectors in a fixed-target mode.
NA 49-future合作组最近提出了一个在CERN SPS上研究强子-核和核-核碰撞中强子产生的新实验方案。该计划的物理目标是:(i)寻找强相互作用物质的临界点和研究核-核碰撞中去精细开始的性质;(ii)测量质子-核碰撞中高横动量下的关联、涨落和强子谱,以便更好地理解核-核结果;(iii)中微子(T2 K)和宇宙射线(Pierre Auger天文台和KASCADE)实验所需的强子-核相互作用中强子产生的测量。核-核程序的物理学在这个介绍中被回顾。
Energy dependence of hadron spectra and yields in p+p and $^7$Be+$^9$Be collisions from the NA61/SHINE experiment at the CERN SPS
NA 61/SHINE关于强相互作用的方案包括研究解除封闭的开始,目的是通过在欧洲核子研究中心的整个SPS动量范围内进行能量和系统大小的扫描,发现强相互作用物质的临界点。到目前为止,已经完成了p+p,$^7$ Be+ $^9$ Be,以及Ar+Sc的扫描。从p+p和Be+Be碰撞的结果现在出现,特别是强子谱和产额的能量依赖性。将介绍这一努力的现状和初步结果。
