LHC第一阶段后的风味物理学和风味对称性

Flavour physics and flavour symmetries after the first LHC phase

Riccardo Barbieri, Dario Buttazzo, Filippo Sala, David M. Straub

摘要:

仅基于味对称性,有两种方法可以有效地描述接近CKM图像的夸克扇区中的味物理:一种是基于$U(3)_q\times U(3)_u\times U(3)_d$(或等效物),另一种是基于$U(2)_q\times U(2)_u\times U(2)_d$(或等效物)。在这种情况下,我们分析了当前的状态的味道物理测量,我们比较它们的影响,在特定的情况下,超对称性,直接搜索新粒子在大型强子对撞机,目前或预见。

英文摘要:

Based on flavour symmetries only, there are two ways to give rise to an effective description of flavour physics in the quark sector close to the CKM picture: one is based on $U(3)_q\times U(3)_u\times U(3)_d$ (or equivalent) and the other on $U(2)_q\times U(2)_u\times U(2)_d$ (or equivalent). In this context we analyze the current status of flavour physics measurements and we compare their impact, in the specific case of supersymmetry, with the direct searches of new particles at the LHC, present or foreseen.
