论文摘要
我们重新审视标量弱重力猜想，并调查施加标量相互作用在重力方面的可能性。更确切地说，我们寻找的后果是，假设对于主要的标量相互作用，相应的引力贡献在非相关性极限中是亚优势。对于单个巨大的标量粒子，这使我们比较了不同类型的电势中的四点自相互作用。对于类似轴的粒子，我们检索了轴弱重力猜想的结果：衰减常数$ f $由普朗克质量界，$ f <{m_ {pl}} $。获得指数势的类似边界。对于四分之一的，权力法和Starobinsky的潜力，我们排除了大型跨普兰克野外游览。然后，我们讨论确定标量质量的模量的情况。我们根据Swampland距离猜想的要求检索指数依赖性。我们还发现具有场依赖性的极端状态质量可再现Kaluza-Klein和绕组模式的行为。在特定情况下，我们的约束可以以精致的de安慰猜想的形式放置。
We revisit the Scalar Weak Gravity Conjecture and investigate the possibility to impose that scalar interactions dominate over gravitational ones. More precisely, we look for consequences of assuming that, for leading scalar interactions, the corresponding gravitational contribution is sub-dominant in the non-relativistic limit. For a single massive scalar particle, this leads us to compare four-point self-interactions in different type of potentials. For axion-like particles, we retrieve the result of the Axion Weak Gravity Conjecture: the decay constant $f$ is bounded by the Planck mass, $f < {M_{Pl}}$. Similar bounds are obtained for exponential potentials. For quartic, power law and Starobinsky potentials, we exclude large trans-Planckian field excursions. We then discuss the case of moduli that determine the scalars masses. We retrieve the exponential dependence as requested by the Swampland Distance Conjecture. We also find extremal state masses with field dependence that reproduces both the Kaluza-Klein and winding modes behaviour. In particular cases, our constraints can be put in the form of the Refined de Sitter Conjecture.
