Recent work by J. Prades and myself on K ! is described. The rst part describes our method to connect in a systematic fashion the short-distance evolution with long-distance matrix-element calculations taking the scheme dependence of the short-distance evolution into account correctly. In the second part I show the results we obtain for the I = 1=2 rule in the chiral limit.

Class-Pi of glutathione s-transferases (GST-Pi) is the specific form of GSTs that are known to participate particularly in the mechanisms of resistance to drugs and carcinogens. This class of the enzyme is referred to as class-P or class-Pi or class π. The accepted terminology in this review article is class-Pi. In this article following a brief description of identified molecular forms of GSTs...

In this work, we provide estimates of the branching ratios, direct $CP$ asymmetries and triple product in $B_{(s)} \to (\pi\pi)(K\pi)$ decays perturbative QCD approach, where $\pi\pi$ $K\pi$ invariant mass spectra are dominated by vector resonances $\rho(770)$ $K^*(892)$, respectively. Some scalar backgrounds, such as $f_0(500,980) \pi\pi$ $K^*_0(1430) K\pi$ also accounted for. The $\rho(700)$ ...
