论文摘要

我们认为形式主义描述了非扰动制度中标量理论中标量场的虚假衰减。我们发现,相对于标量的自我耦合,量规耦合越大,较浅的不稳定真空的局部最小值到消失的点。这提供了获得早期宇宙宇宙学的一致图片的可能性:在高温下,虚假的衰减受到了强烈的青睐,并且宇宙自然而然地朝着稳定的状态发展。

We consider a formalism to describe the false-vacuum decay of a scalar field in gauge theories in non-perturbative regimes. We find that the larger the gauge coupling with respect to the self-coupling of the scalar, the shallower the local minimum of the unstable vacuum, to the point where it disappears. This offers the possibility to obtain a consistent picture of early universe cosmology: at high temperatures, a false-vacuum decay is strongly favoured and the universe naturally evolves towards a stable state.
