早期宇宙中的手征张量粒子

Chiral tensor particles in the early Universe

M. V. Chizhov, D. P. Kirilova

摘要:

本文综述了手征张量粒子在扩展的电弱模型中的地位、实验限制、特征以及在新对撞机上探测手征张量粒子的可能性。确定了早期宇宙等离子体中手征张量粒子的特征相互作用及其相应的宇宙学影响周期。动力学宇宙学效应,即加速弗里德曼膨胀由于密度增加所造成的新粒子的引入,进行了评估。结果表明,手征张量粒子的存在是宇宙学考虑所允许的,也是粒子物理唯象所欢迎的。

英文摘要:

The status of the chiral tensor particles in the extended electroweak model, their experimental constraints, signatures and the possibilities for their detection at the new colliders are reviewed. The characteristic interactions of the chiral tensor particles in the early Universe plasma and the corresponding period of their cosmological influence is determined. The dynamical cosmological effect, namely the speeding of the Friedmann expansion due to the density increase caused by the introduction of the new particles, is evaluated. It is shown that the existence of the chiral tensor particles is allowed from cosmological considerations and welcomed by the particle physics phenomenology.
