$\bar{\mathrm{D}}$ and $\mathrm{B}$ mesons in nuclear medium

Dmeson mass increase by restoration of chiral symmetry in nuclear matter

“…The former, described by interactions between hadrons, includes self-consistent unitarized coupled-channel approaches with flavor SU (3) [5], flavor SU (4) symmetry, and a t-channel vector meson exchange (TVME) model [6], which have been further developed through an improved kernel and renormalization scheme [7,8], improvement beyond zero range approximation [9], and a SU (8) spin-flavor symmetric model implementing heavy quark spin symmetry [10]. There are furthermore results from a chiral SU (3) model extended to SU (4) [11][12][13][14] and a pion exchange model between D and N [15]. The second approach includes the quarkmeson coupling (QMC) model [16,17] and QCD sum rules [18][19][20][21][22].…”

Structure of charmed baryons studied by pionic decays

“…The heavy quark symmetry can be applied also to exotic heavy hadrons such as hadronic molecules[5][6][7][8][9][10][11][12][13][14][15] as well as to the heavy hadrons in nuclear medium[15][16][17][18][19][20][21]. See Ref [22].…”

Mesic nuclei with a heavy antiquark

“…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].…”
