摘要:

在这次演讲中,我总结了最近的研究结果,围绕轴矢量介子的描述动态产生的状态,从赝标介子和矢量介子的相互作用,致力于一些关注的两个$K_1(1270)$状态。然后,我回顾了开放和隐藏的魅力标量和轴向状态的产生,以及最近的一些实验如何支持存在的新的隐藏的魅力标量状态的预测。最近的结果表明,当S=-1时,低激发态的$1/2^+$重子共振可以作为束缚态或两个介子和一个重子在耦合道中的共振而得到。然后显示与S=0的情况下的差异,其中$N^*(1710)$出现也动态地从两个π一个核子系统中产生,但$N^*(1440)$没有出现,表明更复杂的结构的Roper共振。最后,我将说明最近在BABAR和BES发现的X(2175)态如何自然地表现为$ϕK \bar{K}$系统的共振。

英文摘要:

In this talk I summarize recent findings around the description of axial vector mesons as dynamically generated states from the interaction of pseudoscalar mesons and vector mesons, dedicating some attention to the two $K_1(1270)$ states. Then I review the generation of open and hidden charm scalar and axial states, and how some recent experiment supports the existence of the new hidden charm scalar state predicted. I present recent results showing that the low lying $1/2^+$ baryon resonances for S=-1 can be obtained as bound states or resonances of two mesons and one baryon in coupled channels. Then show the differences with the S=0 case, where the $N^*(1710)$ appears also dynamically generated from the two pion one nucleon system, but the $N^*(1440)$ does not appear, indicating a more complex structure of the Roper resonance. Finally I shall show how the state X(2175), recently discovered at BABAR and BES, appears naturally as a resonance of the $ϕK \bar{K}$ system.
