Standard model and CP violations in neutral K- and B-meson systems

Show affiliationsIn this paper we discuss CP violations in 
and 
systems in the framework of the standard model. To start with, using only the experimental values of the moduli of the elements in the first two rows of the CKM matrix and its unitarity, we sought to fix the values of the complex phase angle 
, where 
. We find, in the PDG representation, that 
or 
. Next, we utilize the empirical information on the CP violation parameter 
in neutral kaon decays, the mixing parameter 
, the ratio 
and the theoretical results from the box diagrams for and in order to evaluate the range of values for the angle . The result is 
, which includes both 
and 
obtained earlier. This analysis also allows us to obtain the possible values of 
for a given angle , where is defined by 
. Thus, we are able to predict the possible values of the CP asymmetry parameter a in the neutral B-meson decays to CP self-conjugate states. Our results will be useful as the parameter a is expected to be measured in the near future.
