ISS抬升KKLT模型的有限温度行为
Finite temperature behaviour of the ISS-uplifted KKLT model
摘要:
我们研究了ISS-KKLT模型在模量稳定和提升到零宇宙学常数时的静态相结构。由于超对称破缺扇区和模扇区仅引力耦合,我们预计模对ISS扇区的量子效应可以忽略不计,反之亦然。在这个假设下,我们证明了ISS场最终处于亚稳真空中。其原因不仅是它是热有利的(二阶相变)相比,相变向超对称真空,而是亚稳真空的形式之前,超对称的。这个好的功能完全是由于KKLT部门的存在。我们还表明,超引力效应是可以忽略不计的场空间的起源周围。最后,我们转向模数部门,并表明没有来自ISS部门的不稳定影响。
英文摘要:
We study the static phase structure of the ISS-KKLT model for moduli stabilisation and uplifting to a zero cosmological constant. Since the supersymmetry breaking sector and the moduli sector are only gravitationally coupled, we expect negligible quantum effects of the modulus upon the ISS sector, and the other way around. Under this assumption, we show that the ISS fields end up in the metastable vacua. The reason is not only that it is thermally favoured (second order phase transition) compared to the phase transition towards the supersymmetric vacua, but rather that the metastable vacua form before the supersymmetric ones. This nice feature is exclusively due to the presence of the KKLT sector. We also show that supergravity effects are negligible around the origin of the field space. Finally, we turn to the modulus sector and show that there is no destabilisation effect coming from the ISS sector.
