Abstract

We study the effects of non-universal extra dimensions on the decay widths of the lepton flavour violating (LFV) processes, t --> c l(i)(-) i l(j)(+) and H-0 --> h(0)(A(0)) l(i)(-)l(j)(+) in the general two Higgs doublet model. We consider that the extra dimensions are accessible to the standard model gauge fields and the new Higgs doublet. We observe that the LFV H-0 --> h(0)(tau(+) mu(-) + mu(+)) and H-0 --> A(0)(tau(+)mu(-) + tau(-) mu(+)) Higgs decays are sensitive to the extra dimensions, especially in the case of two spatial ones. This result may ensure a test to determine the compactification scale and the possible number of extra dimensions with the accurate experimental measurements.
