FCC-EE的重夸克机遇和挑战

Heavy-quark opportunities and challenges at FCC-ee

Stéphane Monteil, Guy Wilkinson

摘要:

在FCC-ee预期的$5 \times 10^{12}$ $Z^0$衰变中,美丽和魅力强子的大量产生为味道物理学提供了杰出的机会,通常超过了Belle II的可用机会,并补充了LHC的重味道计划。在重味光谱学、重味粒子的罕见衰变和$C\!P$违反研究中,广泛的测量将是可能的,这将受益于低背景实验环境、高洛伦兹提升和强子种类的全谱的可用性。本文首先概述了重口味物理学中的重要问题,并评估了在FCC-ee开启时可能的理论和实验前景。充分利用FCC-ee的重口味潜力对探测器设计提出了具体的限制和挑战,在某些情况下,这些限制和挑战与该设施的其他物理目标所施加的限制和挑战相矛盾。这些要求和冲突进行了讨论。

英文摘要:

The abundant production of beauty and charm hadrons in the $5 \times 10^{12}$ $Z^0$ decays expected at FCC-ee offers outstanding opportunities in flavour physics that in general exceed those available at Belle II, and are complementary to the heavy-flavour programme of the LHC. A wide range of measurements will be possible in heavy-flavour spectroscopy, rare decays of heavy-flavoured particles and $C\!P$-violation studies, which will benefit from the low-background experimental environment, the high Lorentz boost, and the availability of the full spectrum of hadron species. This essay first surveys the important questions in heavy-flavour physics, and assesses the likely theoretical and experimental landscape at the turn-on of FCC-ee. From this certain measurements are identified where the impact of FCC-ee will be particularly important. A full exploitation of the heavy-flavour potential of FCC-ee places specific constraints and challenges on detector design, which in some cases are in tension with those imposed by the other physics goals of the facility. These requirements and conflicts are discussed.
