Antisymmetric tensor fields are a compelling prediction of string theory. This makes them an interesting target for particle physics because antisymmetric tensors may couple to electromagnetic dipole moments, thus opening a possible discovery opportunity for string theory. The strongest constraints on electromagnetic dipole couplings would arise from couplings to electrons, where these couplings would contribute to Møller and Bhabha scattering. Previous measurements of Bhabha scattering constrain the couplings to , where is the mass of the antisymmetric tensor field and is an effective mass scale appearing in the electromagnetic dipole coupling.
反对称张量场是弦理论的一个引人注目的预言。这使它们成为粒子物理学中一个有趣的研究对象，因为反对称张量可能与电磁偶极矩耦合，从而为弦理论带来了一个可能的发现机会。对电磁偶极耦合的最强限制将来自与电子的耦合，在这种情况下，这些耦合将对莫勒散射和巴哈散射产生影响。先前对巴哈散射的测量将耦合限制在 ，其中 是反对称张量场的质量， 是出现在电磁偶极耦合中的一个有效质量标度。
