Continuous O(d,d) global symmetries emerge in Kaluza-Klein reductions of D-dimensional string supergravities to D-d dimensions. We show that the nongeometric elements of this group effectively act in the D-dimensional parent theory as a hidden bosonic symmetry that fixes its couplings: the β symmetry. We give the explicit β transformations to first order in α^{'} and verify the invariance of the action as well as the closure of the transformation rules.
连续的(O(d,d))全局对称性出现在(D)维弦超引力向(D - d)维的卡鲁扎 - 克莱因约化中。我们表明，该群的非几何元素在(D)维母理论中有效地作为一种隐藏的玻色子对称性起作用，它固定了其耦合：即(\beta)对称性。我们给出了在(\alpha^{'})一阶的显式(\beta)变换，并验证了作用量的不变性以及变换规则的封闭性。
