Constraint from
Indirect CP violation in the Kaon system is usually expressed in terms ofparameter which is the fraction of the CP violating component in the mass eigenstates and which is usually defined as:
where ![]()
Top and charm quarks contribute to the expression of the mixing in K0-K0 system. The calculation of the box diagram gives ![]()
where ![]()
which allows one to write ![]()
where ![]()
The expression actually used in the UT fit is obtained by writing ![]()
in terms of
and the other elements of CKM matrix:
The experimental values we use are summarized in the Table of Inputs. The representation of this constraint in the ![]()
plane is given below.
