<!-- @page { margin: 2cm } P { margin-bottom: 0.21cm } --> The Eotvos effect (the existence of a small difference in the acceleration of falling bodies of two different composition or structure) is one of the most sensitive indicators of changes in fundamental constants.But Bekenstein (2002) showed that in his theory, using particles as a classic static model of matter, there is no Eotvos effect and therefore comply with the Universality of the Free Falling and the Principle of Equivalence. In this talk, we will present results wich are different from those that Bekenstein has obtained. Changing his theory, taking more realistic models of matter, using the THEpsilonMu techniques that were developed by Ligtman-Lee (1975) and Haugan (1979); very small but measurable effects were found.
