Some comments on narrow resonancesDs1*(2.46GeV

AnalyzingDs0*(2317)+in theDKmolecule picture in the Bethe-Salpeter a

“…It was also found that the decay width is consistent with the resolution of the detector À 3:8 MeV. The narrow width of D Ã s0 ð2317Þ þ generates much enthusiasm from both experimental [2,3,5,6] and theoretical physicists [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] to understand the structure of this new state. Various models have been proposed.…”

“…Various models have been proposed. For example, many people identified this new state as a traditional c" s state [7][8][9][10][11][12], while some others thought that it can be an exotic meson state such as a fourquark state [13][14][15], a D s quasibound state [16], a DK bound state [17][18][19], a state of c "…”

“…Up to now the structure issue of the D * s0 (2317) and D s1 (2460) remains an open question. Both mesons have therefore been discussed within various structure assumptions and theoretical frameworks [5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34].…”

“…In the present case, we are interested in the decays D * s0 (2317) → D * s γ and X(3700) → γ J/ψ. The first of these decays has been evaluated assuming varied structures for the resonance within quark models, vector meson dominance, light cone QCD sum rules, etc., [23][24][25][26][27][28][29][30][31][32] and more recently from the point of view of the D * s0 (2317) as a molecular state [33]. The X(3700) has also been predicted in Ref.…”
