暗能量、电弱真空和对撞机现象学

Dark energy, the electroweak vacua and collider phenomenology

Eric Greenwood, Evan Halstead, Robert Poltis, Dejan Stojkovic

摘要:

高维的不可重整化算子可以以许多有趣的方式修改标准模型希格斯势。在这里,我们考虑第二个真空的出现,它可能在宇宙学中发挥重要作用。在一定的参数范围内,通常的二阶电弱相变之后是一阶相变,这可能驱动宇宙的晚期加速膨胀。这样一个潜在的包含扭结的解决方案,这反过来又可以发挥至关重要的作用,在重建的整体形状的潜在的对撞机,我们明确证明。

英文摘要:

Higher dimensional non-renormalizable operators may modify the Standard Model Higgs potential in many interesting ways. Here, we consider the appearance of a second vacuum which may play an important role in cosmology. For the certain range of parameters, the usual second order electroweak phase transition is followed by a first order phase transition that may drive the late time accelerated expansion of the universe. Such a potential contains kink-like solutions which in turn can play a crucial role in reconstructing the global shape of the potential in colliders, as we explicitly demonstrate.
