O' KKLT模型的有限温度行为

Finite Temperature Behaviour of O'KKLT Model

Lilia Anguelova, Vincenzo Calo

摘要:

总结了我们在有限温度下O'Raifeartaigh抬升KKLT模型的研究工作。我们研究系统的参数值的零温度潜力的体积模量有一个dS最小值。有效势的温度依赖部分在超势中的一个指数下具有失控行为,而在超势中的两个指数下,它可以在有限场vevs处具有局部极小值。然而,事实证明,尽管存在这些最小值,零温度dS真空是不稳定的热修正在整个范围内的有效性,我们的近似。

英文摘要:

We summarize our work on the O'Raifeartaigh uplifted KKLT model at finite temperature. We study the system for parameter values for which the zero temperature potential for the volume modulus has a dS minimum. The temperature-dependent part of the effective potential has a runaway behaviour for one exponent in the superpotential, whereas it can have local minima at finite field vevs for two exponents in the superpotential. However, it turns out that, despite the presence of those minima, the zero temperature dS vacuum is not destabilized by thermal corrections within the whole range of validity of our approximations.
