论文摘要
CERN SPS北部地区的高强度Kaon梁的可用性为夸克风味领域中标准模型的敏感测试带来了独特的可能性。对改变风味的中性电流衰减的分支比的精确测量值$ k \toπν\barν$可以为CKM Unitarity提供独特的约束，并可能提供新物理学的证据。基于NA62实验的成功，计划在CERN制定了一项综合计划，该计划将包括实验阶段，以$ K^+\toπ^+t to to $ k^+\toπ^+barν$达到〜5％和$ k_l \toπ^0ν\barν$至〜20％的精确度。这些计划的实验还将进行Lepton风味普遍性测试，Lepton的数量和风味保护测试，并在Kaon部门进行其他精确测量，并在Kaon衰减中搜索奇特的颗粒。我们概述了下一代KAON物理实验的物理目标，检测器需求和项目状态。
The availability of high intensity kaon beams at the CERN SPS North Area gives rise to unique possibilities for sensitive tests of the Standard Model in the quark flavor sector. Precise measurements of the branching ratios for the flavor-changing neutral current decays $K\toπν\barν$ can provide unique constraints on CKM unitarity and, potentially, evidence for new physics. Building on the success of the NA62 experiment, plans are taking shape at CERN for a comprehensive program that will include experimental phases to measure the branching ratio for $K^+\toπ^+ν\barν$ to ~5% and to $K_L\toπ^0ν\barν$ to ~20% precision. These planned experiments will also carry out lepton flavor universality tests, lepton number and flavor conservation tests, and perform other precision measurements in the kaon sector, as well as searches for exotic particles in kaon decays. We overview the physics goals, detector requirements, and project status for the next generation of kaon physics experiments at CERN.
