Search for new physics from $B\to \pi \varphi$

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

We investigate the pure penguin process $B^{-}\to {\pi }^{-}\varphi$ using QCD factorization approach to calculate hadronic matrix elements to the ${\alpha }_s$ order in some well-known NP models. It is…
