Reheating with a Composite Higgs

Djuna Croon, Veronica Sanz, Ewan R. M. Tarrant

摘要:

暴胀子势的平坦性和希格斯玻色子的轻性可能是全局对称性破缺的共同起源。这种情况提供了一个统一的框架,戈德斯通暴胀和复合希格斯粒子,其中暴胀子和希格斯粒子都有一个伪戈德斯通玻色子的性质。暴胀子通过衰变到希格斯粒子和随后通过顶部和大质量矢量玻色子次级产生其他SM粒子来重新加热宇宙。我们发现,通货膨胀的预测和微扰再加热条件是一致的CMB数据的次普朗克值的字段,以及开放的可能性,在TeV尺度的通货膨胀。我们探索这种令人兴奋的可能性,导致对撞机数据和宇宙学约束之间的相互作用。

英文摘要:

The flatness of the inflaton potential and lightness of the Higgs could have the common origin of the breaking of a global symmetry. This scenario provides a unified framework of Goldstone Inflation and Composite Higgs, where the inflaton and the Higgs both have a pseudo--Goldstone boson nature. The inflaton reheats the Universe via decays to the Higgs and subsequent secondary production of other SM particles via the top and massive vector bosons. We find that inflationary predictions and perturbative reheating conditions are consistent with CMB data for sub--Planckian values of the fields, as well as opening up the possibility of inflation at the TeV scale. We explore this exciting possibility, leading to an interplay between collider data and cosmological constraints.
