Implications for new physics from ${\bar{B}}^0\to {\pi }^0{\pi }^0$ and ${\bar{B}}^0\to {\bar{K}}^0{K}^0$

Jian-Feng Cheng, Yuan-Ning Gao, Chao-Shang Huang +1

We have analyzed the ${\bar{B}}^0\to {\pi }^0{\pi }^0$ puzzle in three kinds of models beyond the standard model (SM). It is shown that the minimal flavor violation (MFV) models, the minimal…
