魅力的“第三次”是真正的魅力吗？--宣言
Could Charm's "Third Time" Be the Real Charm? -- A Manifesto
摘要：
最近对$D^0 - \bar D^0$振荡的观察使我们在理论解释上陷入了困境：它们是由SM力单独驱动的，还是涉及新的动力学？对$D$衰变过程中的\cp对称性进行综合分析，可能会解决这个问题。因此，魅力研究可能会收获迄今为止最大的收获：新物理学介入的明确证据。虽然\cp不对称的绝对大小可能最多是适度的，但SM贡献应该更小。因此，“信号”与“噪声”之比--即NP对SM的贡献--对于$D$跃迁可能比对于$B$跃迁更大。提供了一个典型的列表有前途的渠道，其中大部分应该是在强子环境中观察到的。通过分析三体和四体的终态，可以得到有价值的经验教训。
英文摘要：
The recent observation of $D^0 - \bar D^0$ oscillations has left us in a quandary concerning the theoretical interpretation: are they driven by SM forces alone or do they involve new dynamics? A comprehensive analysis of \cp symmetry in $D$ decays can probably resolve the issue. Charm studies might thus haul in their biggest prize yet: clear evidence for the intervention of New Physics. While the absolute size of \cp asymmetries will presumably be modest at best, SM contributions should be much smaller still. Thus the ratio of `signal' to `noise' -- i.e. NP over SM contributions -- might well be larger for $D$ than $B$ transitions. A typical list of promising channels is provided, most of which should be observable in a hadronic environment. Valuable lessons can be obtained by analyzing three- and four-body final states.
