CP invariance condition and rephasing invariance in KM scheme of CP violation is discussed. The CP violation measures in B physics, corresponding to the three angles of unitarity triangle are given in rephasing invariant form. With the obtained results it is shown that the sum of the three CP angles to be measured at B factories becomes $pi$ even if the Kobayashi-Maskwa matrix is not a $3times 3$ unitary matrix under reasonable assumptions.
We identified a set of four rephasing invariant parameters of the CKM matrix. They are found to exhibit hierarchies in powers of $lambda^2$, from $lambda^2$ to $lambda^8$. It is shown that, at the present level of accuracy, only the first three param
The most general lagrangian describing spin 2 particles in flat spacetime and containing operators up to (mass) dimension 6 is carefully analyzed, determining the precise conditions for it to be invariant under linearized (transverse) diffeomorphisms
We present the joint helicity amplitudes for $J/psi to Lambda bar{Lambda}$, $Lambda(barLambda)$ decays to different final states in the helicity frame. Two observables to search for $CP$ violation in $J/psitoLambdabarLambda$ can be expressed with the
Several rotational invariant quantities for the lepton angular distributions in Drell-Yan and quarkonium production were derived several years ago, allowing the comparison between different experiments adopting different reference frames. Using an in
The strong coupling constant $1/g^2$ and the vacuum angle $theta$ of the SU(3) Yang-Mills theory are investigated in the infrared limit under the renormalization group flow. It is shown that the theory has an infrared attractive fixed point at $1/g^2
