# Double heavy tri-hadron bound state with strange flavor

Through the Born-Oppenheimer Approximation, we have performed a comprehensive investigation of the DD∗K, DD¯$\overline D$*K, BB∗K¯$\overline K$ and BB¯$\overline B$*K¯$\overline K$ molecular states. In the framework of One-Pion Exchange model as well as the treatments of the coupled-... Ausführliche Beschreibung

In the framework of One-Pion Exchange model as well as the treatments of the coupled-channel eﬀects and S-D wave mixing, we find a loosely bound tri-meson molecular state these systems with the isospin configuration |0,12${1 \over 2}$, ±12${1 \over 2}$> and quantum number I(JP) = 1/2(1−), where the, 12${1 \over 2}$ is the total isospin of the three-body system, the 0 is the isospin of the D∗K, D¯$\overline D$*K, B∗K¯$\overline K$ and B¯$\overline B$∗K¯$\overline K$. With the estimated error, the mass of the DD∗K or DD¯$\overline D$∗K molecule is 4317.92−4.32+3.66$4317.92_{ - 4.32}^{ + 3.66}$ MeV or 4317.92−6.55+6.13$4317.92_{ - 6.55}^{ + 6.13}$MeV. We also extend our calculations to the bottom sector and find tri-meson bound states for the BB∗K¯$\overline K$ and BB¯$\overline B$*K¯$\overline K$ with the mass 11013.65−8.84+8.49$11013.65_{ - 8.84}^{ + 8.49}$ MeV and 11013.65−9.02+8.68$11013.65_{ - 9.02}^{ + 8.68}$MeV respectively. 0 8 |i In  |t EPJ Web of Conferences  |g  (01.01.2019)  |w (DE-601)DOAJ000093130  |x 2100-014X 4 0 |u http://dx.doi.org/10.1051/epjconf/201920206007 4 0 |y DOAJ  |u https://doaj.org/article/e13ab3a9f60f43b5840d1256870d7104 4 0 |u https://www.epj-conferences.org/articles/epjconf/pdf/2019/07/epjconf_charm2018_06007.pdf 4 0 |u https://doaj.org/toc/2100-014X |a GBV_DOAJ |a AR |j 2019  |b 01  |c 01
