探测LHC上的最小味道违反

Probing Minimal Flavor Violation at the LHC

Yuval Grossman, Yosef Nir, Jesse Thaler, Tomer Volansky, Jure Zupan

摘要:

如果大型强子对撞机的实验发现了与标准模型费米子耦合的新粒子,那么ATLAS和CMS的测量可以帮助我们理解味道之谜。我们通过研究额外的SU(2)-单态下型夸克在LHC范围内的情况来证明这一说法。通过测量质量、生产截面和相对衰变率,原则上可以排除最小风味破坏(MFV)。相反,这些测量可以探测MFV应用于新自由度的方式。我们的许多结论在比标准模型的这个特定扩展更一般的背景下是有效的。

英文摘要:

If the LHC experiments discover new particles that couple to the Standard Model fermions, then measurements by ATLAS and CMS can contribute to our understanding of the flavor puzzles. We demonstrate this statement by investigating a scenario where extra SU(2)-singlet down-type quarks are within the LHC reach. By measuring masses, production cross sections and relative decay rates, minimal flavor violation (MFV) can in principle be excluded. Conversely, these measurements can probe the way in which MFV applies to the new degrees of freedom. Many of our conclusions are valid in a much more general context than this specific extension of the Standard Model.
