Induced Violation of Weak Equivalence Principle in the Brans-Dicke Theory
Yasunori Fujii
Abstract
A quantum correction to the Brans-Dicke theory due to interactions among matter fields is calculated, resulting in violation of WEP, hence giving a constraint on the parameter ω far more stringent than accepted so far. The tentative estimate gives the lower bounds 106 and 108 for the assumed force-range 1m and 1AU, respectively.
