这篇博客探讨了暗物质在中子星中的捕获现象，涉及Pomeron的bootstrap理论，有效场论中的熵约束，以及复合Nambu-Goldstone Higgs模型。文章还讨论了从相对熵角度理解的positivity bound，以及它如何与弱重力猜想和热力学第二定律相联系。

Entropy Constraint on Effective Field Theory
https://arxiv.org/pdf/2201.00931.pdf

Abstract: Positivity bounds of higher derivative operators are derived from analyticity, causality and unitarity in effective field theory. We show that the positivity bounds can be derived from the non-negativity of relative entropy between a theory with and without interactions between heavy and light degrees of freedom. We prove that the interactions increase thermodynamic entropy at fixed energy and charge, which implies the extremality relations of a wide class of black holes exhibiting Weak-Gravity-Conjecture-like behavior. As the entropy constraint is a consequence of Hermiticity of Hamiltonian operator, any UV theory violating the entropy constraint would not respect the second law of the thermodynamics.

The Composite Nambu–Goldstone Higgs
https://arxiv.org/pdf/1506.01961.pdf

Abstact: The composite Higgs scenario, in which the Higgs emerges as a composite pseudo-Nambu-Goldstone boson, is extensively reviewed in these Notes. The material is presented in a pedagogical fashion, with great emphasis on the conceptual and technical foundations of the construction. A comprehensive summary of the flavor, collider and electroweak precision phenomenology is also presented.
