This radion behaves like a weak interaction singlet scalar field, coupling to matter through the trace of the energy momentum tensor. We find that it can induce a sizable correction to the weak mixing angle if the vacuum expectation value and the mass of the radion is around TeV. We also comment on the contribution to the $K_L-K_S$ mass difference and to $(g-2)_μ$.LaTeX file of 15 pages with 7 eps figuresHigh Energy Physics - PhenomenologyThe radion contribution to the weak mixing angletext
