在弱场极限下，利用电磁对偶性和SL（2，R）对称性所决定的耦合，构造了一个包含轴子场和介子场的Born-Infeld非线性真空电动力学的推广.除了牛顿引力常数外，该模型还包含一个基本耦合参数b 0。在没有轴子和介子相互作用的情况下，它在极限b 0 <$∞下简化为麦克斯韦的线性真空理论，而在有限b 0下简化为原始的Born-Infeld模型。球对称的静态部门的理论探讨在一个平坦的背景时空中的约旦框架，数值证据表明存在的轴子-介子束缚态具有限制的电通量。
A generalization of Born–Infeld non-linear vacuum electrodynamics involving axion and dilaton fields is constructed with couplings dictated by electromagnetic duality and SL(2,R) symmetries in the weak field limit. Besides the Newtonian gravitational constant the model contains a single fundamental coupling parameter b0. In the absence of axion and dilaton interactions it reduces in the limit b0↦∞ to Maxwellʼs linear vacuum theory while for finite b0it reduces to the original Born–Infeld model. The spherically symmetric static sector of the theory is explored in a flat background spacetime in the Jordan frame where numerical evidence suggests the existence of axion–dilaton bound states possessing confined electric flux.
