Description
Summary:The rare top decay t [right arrow] c[bar.l]l, which involves flavor violation, is studied as a possible probe of new physics. This decay is analyzed with one of the simplest Standard Model extensions with additional gauge symmetry formalism. The considered extension is the Left-Right Symmetric Model, including a new neutral gauge boson Z' that allows one to obtain the decay at tree level through Flavor-Changing Neutral Currents (FCNC) couplings. The neutral gauge boson couplings are considered diagonal but family non-universal in order to induce these FCNC. We find BR(t [right arrow] c[bar.l]l) ~ [10.sup.-13] for the range 1 TeV [less than or equal to] [M.sub.Z'] [less than or equal to] 3TeV.
