Estimate of Wolfenstein's Parameters rho and eta Based on a Geometry Viewpoint to the Weak CP Phase
Abstract
Description
Based on a geometric postulation on the weak CP phase in Cabibbo-Kobayashi-Maskawa (CKM) matrix, a positive rho is asserted. Besides, 0.18<eta<0.54 and 0.048<rho<0.140 are permitted by the present data. The corresponding geometric constraint on Wolfenstein's parameters is also worked out. We find that, according to the geometry viewpoint, eta and rho satisfy an approximate linear relation. These results can be put to the more precisely tests in near future.
