Abstract :
Final-state interaction effects in charmless image decays are studied. Our main results are as follows: (i) Theoretical results are in agreement with data in the presence of FSI. (ii) The image and image decay rates are suppressed and enhanced respectively by FSI. (iii) The FSI has large impact on direct CP asymmetries (image) of many modes. (iv) The deviation(image) between image and image can be understood in the FSI approach. (v) Sizable and complex color-suppressed tree amplitudes, which are crucial for the large image rate and image, are generated through exchange rescattering. (vi) The image direct CP violation is very small and is not affected by FSI. (vii) Several image decay rates are enhanced. (viii) Time-dependent CP asymmetries S in image decays are studied. The image is very small (image). We found that the asymmetries image for image, image and image decays are all below 0.06.
