论文摘要
KKLT方案成功地稳定了体积模量,并在IIB型字符串理论中构建了稳定的DE Sitter(DS)真空。我们重新审视以调查在KKLT方案中Oscillon(或I-Ball)形成的可能性,当时音量模量最初从DS最小值移位。特别注意体积模量的物理现实初始条件,这在文献中没有引起。使用晶状体模拟,我们发现俄亥俄州不会形成,除非最初将体积模量放置在非常接近局部最大值的位置,这需要严重的微调。
KKLT scenario has succeeded in stabilizing the volume modulus and constructing metastable de Sitter (dS) vacua in type IIB string theory. We revisit to investigate the possibility of the oscillon (or I-ball) formation in the KKLT scenario when the volume modulus is initially displaced from the dS minimum. Special attention is paid to physically realistic initial conditions of the volume modulus, which was not taken in the literature. Using lattice simulations, we find that oscillons do not form unless the volume modulus is initially placed at very near the local maximum, which requires severe fine-tuning.
