M/sup 0/-M/sup 0/ matrix elements in a relativized quark model
Journal Article

· Phys. Rev. D; (United States)
Matrix elements of the type are evaluated using a relativized quark model for the K/sup 0/, D/sup 0/, B/sup 0/, and B/sub s//sup 0/ systems where scrO/sub 1/ = (q-bar..gamma../sup ..mu../(1-..gamma../sub 5/)q)(q-bar..gamma.. /sub ..mu../(1-..gamma../sub 5/)q), scrO/sub 2/ = (q-bar(1-..gamma../sub 5/)q) (q-bar(1 +..gamma../sub 5/)q), scrO/sub 3/ = (q-bar..gamma../sub ..mu../(1-..gamma../sub 5/)q)(q-bar..gamma.. /sup ..mu../(1+..gamma../sub 5/)q), and scrO/sub 4/ = (q-bar(1-..gamma../sub 5/)q)(q-bar(1-..gamma.. /sub 5/)q). The pseudoscalar-meson decay constants f/sub p/ are first calculated using various approximations to set the scale of the matrix elements' magnitude and to estimate their accuracy. The matrix elements are then calculated, again using various approximations, and are presented as ratios with respect to the vacuum saturation value of scrO/sub 1/. When relativistic effects are included we find that significant enhancements are indicated for the scrO/sub 2/, scrO/sub 3/, and scrO/sub 4/ matrix elements which will alter the resulting bounds on new interactions. As an illustration we find that the right-handed W boson of left-right-symmetric theories must have a mass of at least 3.8 TeV.
