In order to explain the recently measured deviation by the BNL experiment on (g-2)(mu), it is necessary that these scalars are either light or couple strongly with muons. Here we explore this last possibility. We show that a scalar with mass of the order of 10(2) GeV provides significant contribution to (g-2)(mu) if the Yukawa coupling is about 10(-1). We suggest scenarios where this comes about naturally.4engArtigo10.1103/PhysRevD.64.117701WOS:000172450600100Acesso restritoWOS000172450600100.pdf
