Description

We study the possibility of the formation of mesons ($K,~D,~B$ as well as $\phi$, charmonia, and bottomonia) bound in atomic nuclei.
The open strange and open heavy flavor mesic-nuclei are studied using the mass modifications of the mesons in nuclear matter within the quark meson coupling model [1,2].
The hidden-flavor ($\phi$) meson-nucleus bound states are studied with the mass modification of $\phi$ meson using the tree level $\phi K\bar{K}$ lagrangian with the in-medium masses of $K$ and $\bar{K}$ mesons as calculated within the QMC model.
On the other hand, masses of the hidden heavy flavor mesons are calculated using a generalized linear sigma model, due to medium modification of the dilaton field, which simulates the gluon condensates of QCD [3].
These studies are relevant for the experimental investigation of the strong interaction in the low-energy regime in understanding the low-energy meson-baryon interaction with implications in diverse fields, from the search for exotic mesic nuclear bound states, to the structure of compact astrophysical objects like neutron stars.
The upcoming $\rm{\bar{P}ANDA}$ at FAIR, J-PARC-E29, J-PARC-E88, and JLab experiments will be particularly significant for such studies.
