非粒子的霍金辐射

Hawking radiation of unparticles

De-Chang Dai, Dejan Stojkovic

摘要:

非粒子的自由度,无论与标准模型粒子的耦合有多弱,都必然会影响黑洞的演化,黑洞会热衰变为所有可用的自由度。本文发展了一种计算3+1及高维黑洞标量非粒子灰体因子的方法。我们发现,非粒子发射的功率可能与普通粒子发射的功率大不相同。根据模型中的参数,非粒子可能会成为主导通道。这是特别感兴趣的小原始黑洞,也在低尺度量子引力的实验签名可能会受到显着影响的模型。我们还讨论了(目前未知的)unparticle归一化的结果的敏感性。

英文摘要:

Unparticle degrees of freedom, no matter how weakly coupled to the standard model particles, must affect the evolution of a black hole, which thermally decays into all available degrees of freedom. We develop a method for calculating the grey-body factors for scalar unparticles for 3+1 and higher dimensional black holes. We find that the power emitted in unparticles may be quite different from the power emitted in ordinary particles. Depending on the parameters in the model, unparticles may become the dominant channel. This is of special interest for small primordial black holes and also in models with low scale quantum gravity where the experimental signature may significantly be affected. We also discuss the sensitivity of the results on the (currently unknown) unparticle normalization.
