Thin-shell wormholes from the regular Hayward black hole

We discuss the formalism of the two Higgs doublet model of type III with CP violation from CP-even CP-odd mixing in the neutral Higgs bosons. The flavor-changing interactions among neutral Higgs bosons and fermions are presented at tree level in this type of model. These assumptions allow the study of rare top decays mediated by a neutral Higgs boson; particularly we are interested in $trightarrow c l^+l^-$ . For this process we estimate the upper bounds of the branching ratios $mathrm{Br }(trightarrow c tau ^+tau ^-)$ of the order of $10^{-9}sim 10^{-7}$ for a neutral Higgs boson mass equal to 125 GeV and $tan beta =1$ , 1.5, 2, 2.5. For the case of $trightarrow c tau ^+tau ^-$ the number of possible events is estimated to range from 1 to 10 events, which could be observed in future experiments at LHC with a luminosity of 300  $hbox {fb}^{-1}$ and 14 TeV for the energy of the center of mass. Also we estimate that the number of events for the process $trightarrow c l^+l^-$ in different scenarios is of the order of 2,500.
