Probing flavor-changing top-charm-scalar interactions in e+e- collisions
Abstract
Because of the very large mass of the top quark, probing the flavor-changing top-charm-scalar vertex is clearly very important. Fortunately the largeness of mt endows a unique signature to the resulting reaction, i.e., e+e--->tc¯(t¯c), that should be helpful in identification of such events. A two Higgs doublet model, without natural flavor conservation, is used to give an illustrative estimate for the rate for these reactions.
