论文摘要
我们重新审视了最初在Arxiv：1710.01741中呈现的普遍纹理零纹理（UTZ）模型的现象学预测，并根据改进的实验约束和数值分析技术来对其进行更新。特别是，我们已经开发了内部马尔可夫链蒙特卡洛（MCMC）算法，以详尽地探索UTZ的可行参数空间，考虑到该模型有效的运营商产品扩展中的领先和临时贡献。我们还首次提取了（限制性较差的）麻质竞争阶段的可靠UTZ预测，并且比率可观察到的比率可观察到（例如（例如）振荡，$β$ -DECEAD和宇宙学过程所探测的中微子质量。因此，我们对最初在Arxiv：1710.01741中最初提出的原始现象学分析进行了显着改进，并最终表明UTZ仍然是一种最小，可行，有吸引力的风味理论。我们的结果还进一步证明了使用MCMC例程可靠地检查多参数风味模型的潜力。
We revisit the phenomenological predictions of the Universal Texture Zero (UTZ) model of flavour originally presented in arXiv:1710.01741, and update them in light of both improved experimental constraints and numerical analysis techniques. In particular, we have developed an in-house Markov Chain Monte Carlo (MCMC) algorithm to exhaustively explore the UTZ's viable parameter space, considering both leading- and next-to-leading contributions in the model's effective operator product expansion. We also extract -- for the first time -- reliable UTZ predictions for the (poorly constrained) leptonic CP-violating phases, and ratio observables that characterize neutrino masses probed by (e.g.) oscillation, $β$-decay, and cosmological processes. We therefore dramatically improve on the proof-in-principle phenomenological analysis originally presented in arXiv:1710.01741, and ultimately show that the UTZ remains a minimal, viable, and appealing theory of flavour. Our results also further demonstrate the potential of robustly examining multi-parameter flavour models with MCMC routines.
