• Resumen

  • We present a study of the flavor changing decays ɸ → tc (ɸ = H_(F), A_(F)) of the CP-even and CP-odd scalar flavons at the large hadron collider and its next stage, the high-luminosity large hadron collider. The theoretical framework is an extension of the standard model that incorporates an extra complex singlet and invokes the Froggatt-Nielsen mechanism with an Abelian flavor symmetry. The projected exclusion and discovery regions in terms of the model parameters are reported. We find that A_(F) could be detected at the LHC by considering a reasonable scenario of the model parameter space. As far as H_(F) is concerned, we also found promising results that could be verified experimentally at the high-luminosity LHC.
