讨论了弱背景引力场中的自由质量高自旋场。与自旋为1的情况相反，更高自旋的场应该与曲率有非平凡的非最小耦合。一个精确的分析给出了自旋2的情况下，它表明，两个条件应满足之间的五个非最小耦合常数，我们得到的哈密顿和拉格朗日形式主义。检验了质量引力理论的线性化极限确实存在满足条件的非最小耦合。我们还讨论了自旋为3时非最小耦合的形式。
Free massive higher spin fields in weak background gravitational fields are discussed. Contrary to the spin 1 case, higher spin fields should have nontrivial non-minimal couplings to the curvature. A precise analysis is given for the spin 2 case, and it is shown that two conditions should be satisfied among five non-minimal coupling constants, which we derive both in the Hamiltonian and Lagrangian formalisms. It is checked that the linearized limit of the massive gravity theory indeed has the non-minimal couplings that satisfy the conditions. We also discuss the form of the non-minimal couplings for the spin 3 case.
