A cosmological model based on two scalar fields is proposed. The first of these, , has mass , while the second, , is massless. The pair are coupled through a “Higgs portal”. First, we show how the model reproduces the Friedmann equations if the square of the mass of the field is proportional to the cosmological constant and represents the quintessence field. Quantum corrections break the conformal symmetry, and the field acquires a mass equal to . The perturbative approach with is consistent with the bounds for ; moreover, by using dimensional analysis, we estimate eV, which is in accordance with what is expected in the quintessence scenario. The acceleration of the universe is proportional to , we conclude that for very long times, the solution of the equation of motion approaches and the universe continues to accelerate, with a constant acceleration.

卡罗尔极限中的精髓和希格斯入口


提出了基于两个标量场的宇宙学模型。其中第一个 ， 具有质量 ，而第二个 ， ，则没有质量。这对粒子通过“希格斯门户”耦合。首先，我们展示如果场质量的平方与宇宙常数成正比并代表本质场，则模型如何重现弗里德曼方程。量子校正打破了共形对称性，场获得的质量等于 。的扰动方法与 的界限一致；而且，通过量纲分析，我们估计了eV，这与精华场景中的预期是一致的。宇宙的加速度与 成正比，我们得出结论，在很长一段时间内，运动方程的解接近，宇宙继续以恒定的加速度加速。
