连续统超伴子

Continuum Superpartners

Hsin-Chia Cheng

摘要:

在严格共形理论中,没有粒子。激发具有连续谱,被格奥尔基称为“非粒子”。我们考虑标准模型的近似共形扇区的超对称扩展。共形对称性在红外线中被柔和地破坏,从而产生间隙。然而,如果没有限制,光谱仍然可以在间隙上方具有连续性。使用AdS/CFT对应,这可以通过在扭曲的额外维度中的软壁来实现。当超对称性破缺时,标准模型粒子的超伴子可能只是能隙之上的连续体。对撞机的信号可能与标准的超对称场景大不相同,对连续谱超伴子的实验搜索可能非常具有挑战性。

英文摘要:

In an exact conformal theory there is no particle. The excitations have continuum spectra and are called "unparticles" by Georgi. We consider supersymmetric extensions of the Standard Model with approximate conformal sectors. The conformal symmetry is softly broken in the infrared which generates a gap. However, the spectrum can still have a continuum above the gap if there is no confinement. Using the AdS/CFT correspondence this can be achieved with a soft wall in the warped extra dimension. When supersymmetry is broken the superpartners of the Standard Model particles may simply be a continuum above gap. The collider signals can be quite different from the standard supersymmetric scenarios and the experimental searches for the continuum superpartners can be very challenging.
