We analyze the modifications that a dense nuclear medium induces in the and . In the vacuum, we consider them as isoscalar and ▪-wave bound states, which are dynamically generated from effective interactions that lead to different Weinberg compositeness scenarios. Matter effects are incorporated through the two-meson loop functions, taking into account the self energies that the , ▪, , and ▪ develop when embedded in a nuclear medium. Although particle-antiparticle [] lineshapes are the same in vacuum, we find extremely different density patterns in matter. This charge-conjugation asymmetry mainly stems from the very different kaon and antikaon interaction with the nucleons of the dense medium. We show that the in-medium lineshapes found for these resonances strongly depend on their /▪ molecular content, and discuss how this novel feature can be used to better determine/constrain the inner structure of these exotic states.

电荷共轭不对称性和分子含量：物质中的[公式省略]


我们分析了致密核介质在 和 中引起的修饰。在真空中，我们将它们视为等标量和波束缚态，它们是通过有效相互作用动态生成的，从而导致不同的温伯格复合性场景。物质效应通过双介子环函数纳入，考虑到 、 ▪ 、 和 ▪ 嵌入核介质时产生的自能。尽管粒子-反粒子[]线形在真空中是相同的，但我们发现物质中的密度模式截然不同。这种电荷共轭不对称性主要源于高介子和反高介子与致密介质核子的相互作用非常不同。我们表明，这些共振发现的介质内线形很大程度上取决于它们的分子含量，并讨论了如何利用这一新特征来更好地确定/约束这些奇异态的内部结构。
