稀有魅力衰变:实验综述

Rare charm decays: an experimental review

Francesco Dettori

摘要:

间接研究,特别是稀有衰变,已被证明是一个富有成果的领域,以寻找新的物理学超越标准模型。虽然下夸克扇区(B和K)已被详细研究,但由于其观测值的期望值较小且理论不确定性较高,因此对魅力衰变的关注较少。最近,人们对稀有魅力搜索的兴趣又重新高涨起来。本文综述了在粲强子中寻找稀有衰变的实验现状。虽然标准模型的速率还没有达到,但目前的实验极限已经对新物理模型造成了限制。

英文摘要:

Indirect searches, and in particular rare decays, have proven to be a fruitful field to search for New Physics beyond the Standard Model. While the down-quark sector (B and K) have been studied in detail, less attention was devoted to charm decays due to the smaller expected values and higher theoretical uncertainties of their observables. Recently a renewed interest is growing in rare charm searches. In this article we review the current experimental status of searches for rare decays in charmed hadrons. While the Standard Model rates are yet to be reached, current experimental limits are already putting constraints on New Physics models.
