Probing 4 X 4 quark mixing matrix
Gurjit Kaur, Gulsheen Ahuja, Dheeraj Shukla +1
Without adhering to any specific model, we have presented 4 X 4 quark mixing matrix as an extension of the 3 X 3 PDG parametrization of the CKM matrix. Using unitarity constraints…

Hierarchy of CKM matrix elements and implications of unitarity
Gurjit Kaur, Gulsheen Ahuja, Dheeraj Shukla +1
The hierarchy amongst the CKM matrix elements, highlighted recently by Luo and Xing, has been rigorously revisited using the PDG parameterization incorporating unitarity constraint…

Revisiting representations of quark mixing matrix
Gurjit Kaur, Aakriti Bagai, Gulsheen Ahuja +1
Using unitarity, unlike the approaches available in the literature, we have constructed 9 independent representations of CKM matrix starting with each of the 9 elements of the matr…
