非Pauli-Fierz大质量引力子

Non Pauli-Fierz Massive Gravitons

Gia Dvali, Oriol Pujolas, Michele Redi

摘要:

我们研究了大质量引力子的一般洛伦兹不变量理论。我们发现,与标准的传说相反,存在一致的理论,引力子质量项违反保利-菲尔斯结构。对于引力子是共振的理论,如果在高能量下与保利-菲耶兹的偏差变得足够小,这并不意味着标量鬼的存在。这些类型的质量项是在更高维度中DGP模型的任何一致实现所必需的。

英文摘要:

We study general Lorentz invariant theories of massive gravitons. We show that, contrary to the standard lore, there exist consistent theories where the graviton mass term violates Pauli-Fierz structure. For theories where the graviton is a resonance this does not imply the existence of a scalar ghost if the deviation from Pauli-Fierz becomes sufficiently small at high energies. These types of mass terms are required by any consistent realization of the DGP model in higher dimension.
