重味强子中的$CP$破坏

$CP$ violation in heavy-flavour hadrons

Greig A. Cowan

摘要:

测量$B$介子衰变中的$CP$破坏观测量可以用来确定幺正三角的角度,从而探索Cabibbo-Kobayashi-Maskawa标准模型范式之外的新物理学的表现。特别感兴趣的是角度$γ$和$β$的精确测量。同样重要的是研究涉及$B_s^0$介子的$CP$ -破坏,特别是相位$ϕ_s$,这是LHC味道物理学中的黄金观测。补充这些研究是继续寻找直接和间接的$CP$违反魅力系统,其中的实验精度现在是在$10^{-3}$的水平。我将提出新的和最近的结果,在这些主题,并在$CP$ -违反搜索重子衰变,特别强调在大型强子对撞机的测量计划。

英文摘要:

Measurements of $CP$-violating observables in $B$ meson decays can be used to determine the angles of the Unitarity Triangle and hence probe for manifestations of New Physics beyond the Cabibbo-Kobayashi-Maskawa Standard Model paradigm. Of particular interest are precise measurements of the angles $γ$ and $β$. Also of great importance are studies of $CP$-violation involving $B_s^0$ mesons, in particular the phase $ϕ_s$, which is a golden observable in flavour physics at the LHC. Complementary to these studies is the continuing search for direct and indirect $CP$-violation in the charm system, where the experimental precision is now at the $10^{-3}$ level. I will present new and recent results in these topics, and in $CP$-violation searches in baryon decays, with specific emphasis on the measurement programme at the LHC.
