新的Proca交互类

New class of Proca interactions

Claudia de Rham, Victor Pozsgay

摘要:

我们提出了一类新的Proca相互作用,享受一个非平凡的约束,因此传播一个健康的大规模自旋1场的自由度的正确数量。我们表明,散射振幅总是不同于那些广义Proca。这意味着这里提出的新的相互作用类与广义Proca是真正不同的,两者之间不可能有局部场的重新定义。在弯曲的时空,大规模的重力是自然的协变,但我们展示了如何其他类的协变可以被认为是。

英文摘要:

We propose a new class of Proca interactions that enjoy a non-trivial constraint and hence propagates the correct number of degrees of freedom for a healthy massive spin-1 field. We show that the scattering amplitudes always differ from those of the Generalized Proca. This implies that the new class of interactions proposed here are genuinely different from the Generalized Proca and there can be no local field redefinitions between the two. In curved spacetime, massive gravity is the natural covariantization but we show how other classes of covariantizations can be considered.
