“…The D (B) meson in nuclear systems is a simple system, because there is no annihilation channel by qq, in contrast to the case of its antiparticle D ( B) in nuclear medium. They have both been studied in many theoretical works: the quark-meson coupling model [6,7], the mean-field approach [8][9][10][11], the flavor SU(4) symmetry [12][13][14][15], the flavor-spin SU (8) symmetry [16], the pion-exchange interaction [17,18], the QCD sum rules [19][20][21][22][23][24], and the Nambu-Jona-Lasinio model [25]. As advanced topics, there are studies on chiral symmetry breaking [26][27][28][29], the Kondo effect [30][31][32] 1 , and the spin-isospin correlated nuclear matter [38].…”
