Muon accelerators and colliders

Oral contribution

缪子对撞机具有高对撞能量和干净本底的优势，对于寻找新物理过程有着特别的潜力。而当前粒子物理对于早期宇宙的诸多问题还尚未有确切的答案，比如宇宙正反物质不对称该如何解释，电弱相变的确切图案是怎样的？缪子对撞机的高对撞能量给予了检验早期宇宙这些问题的可能性，其干净的本底和较大的亮度有望让我们对上述问题的参数空间有着更进一步的检验。在这个报告中，我们将寻找缪子对撞机上的新物理过程与早期宇宙的关联，尤其是揭示宇宙正反物质不对称的轻子生成机制，和电弱相变图案。

Muon accelerators and colliders

Oral contribution

Motivated by the recent rare B decays measurements, we study the matching procedure of operators O9,O10 in the low energy effective Hamiltonian and operators in the Standard Model effective theory (SMEFT). It is noticed that there are more related operators in the SMEFT whose coefficients can not be determined only from the low-energy data from B physics. We demonstrate how to determine these...

Neutrino physics

Oral contribution

1. We propose a neutrino lepton collider where the neutrino beam is generated from TeV scale muon decays. Such a device would allow for a precise measurement of the W mass based on single W production. Although it is challenging to achieve high instantaneous luminosity with such a collider, we find that a total luminosity of 0.1/fb can already yield competitive physics results
2. We further...

50. Muon Colliders

Prof. Jingyu Tang ( University of Science and Technology of China)

Muon accelerators and colliders

Oral contribution

Muon collider is a potential accelerator solution for future particle physics in energy frontier. It provides unique properties to the research in multi-TeV energy range, as compared to other accelerator solutions such as proton-proton colliders and linear electron-positron colliders. This talk reviews the worldwide study history of muon colliders since 1990’s, different design schemes, R&D...
