deSitter膜世界中的牛顿势

Newton potential in deSitter braneworld

Shin'ichi Nojiri, Sergei D. Odintsov

摘要:

利用5dAdS或dS体中deSitter(dS)膜上的引力子相关器,计算了四维牛顿势。对于AdS体中的平膜,Randall-Sundrum结果得到了恢复。对于dS体中的平膜,与AdS体相比,Newton势中的子导项($1/r^3$)的符号为负.根据dS/CFT对应,这表明对偶CFT应该是非酉的(例如,高阶导数共形理论)。

英文摘要:

Using graviton correlator on deSitter (dS) brane in 5d AdS or dS bulk we calculate the four-dimensional Newton potential. For flat brane in AdS bulk the Randall-Sundrum result is recovered. For flat brane in dS bulk the sign of subleading ($1/r^3$) term in Newton potential is negative if compare with AdS bulk. In accordance with dS/CFT correspondence this indicates that dual CFT should be non-unitary (for example, higher derivative conformal theory).
