Description of the newly observed Ωc∗\Omega^{*}_c states as molecular states

In this work, we study the strong decays of the newly observed $\Omega^{*}_c(3185)$ and $\Omega^{*}_c(3327)$ assuming that $\Omega^{*}_c(3185)$ and $\Omega^{*}_c(3327)$ as $S$-wave $D\Xi$ and $D^{*}\Xi$ molecular state, respectively. Since the $\Omega_c^{*}$ was observed in the $\Xi_c^{+}K^{-}$ invariant mass distributions, the partial decay width of $\Omega^{*}_c(3185)$ and $\Omega^{*}_c(3327)$ into $\Xi_c^{+}K^{-}$ through hadronic loops are evaluated with the help of the effective Lagrangians. Moreover, the decay channel of $\Xi_c^{'}\bar{K}$ is also included. The decay process is described by the $t$-channel $\Lambda$, $\Sigma$ baryons and $D_s$, $D_s^{*}$ mesons exchanges, respectively. By comparison with the LHCb observation, the current results support the $\Omega^{*}_c(3327)$ with$J^P=3/2^{-}$ as pure $D^{*}\Xi$ molecule while the $\Omega^{*}_c(3327)$ with $J^P=1/2^{-}$ can not be well reproduced in the molecular state picture. In addition, the spin-parity $J^P=1/2^{-}$ $D\Xi$ molecular assumptions for the $\Omega^{*}_c(3185)$ can't be conclusively determined. It may be a meson-baryon molecule with a big $D\Xi$ component. Although the decay width of the $\Omega_c^{*}\to{}\bar{K}\Xi_c^{'}$ is of the order several MeV, it can be well employed to test the molecule interpretations of $\Omega^{*}_c(3185)$ and $\Omega^{*}_c(3327)$

2-Cyclo­hexyl-4-[(3,5-dimethyl­piperidin-1-yl)meth­yl]-5-methyl­phenol

The title compound, C21H33NO, crystallizes with three independent mol­ecules in the asymmetric unit. The cyclo­hexane and piperidine rings adopt chair conformations. The crystal packing is stabilized by inter­molecular O—H⋯N and C—H⋯O hydrogen bonds, and by weak π–π stacking inter­actions [centroid–centroid distance = 3.876 (2) Å]

Aqua­[2-(3-carb­oxy-5-carboxyl­atophen­oxy)acetato-κO 1]bis­(1,10-phenanthroline-κ2 N,N′)manganese(II) dihydrate

In the title complex, [Mn(C10H6O7)(C12H8N2)2(H2O)]·2H2O, the MnII atom is coordinated by two O atoms from one 2-(3-carb­oxy-5-carboxyl­atophen­oxy)acetate (HOABDC2−) dianion and one water mol­ecule and by four N atoms from two 1,10-phenanthroline (phen) ligands within a distorted octa­hedral geometry. O—H⋯O hydrogen bonding between –COOH and –COO− groups of adjacent mol­ecules and between carboxyl­ate groups and coordinated and uncoordin­ated water mol­ecules leads to a three-dimensional structure which is further stabilized by weak π–π inter­actions of adjacent phen ligands with centroid–centroid separations of 4.2932 (1) Å

catena-Poly[cobalt(II)-bis­(μ-2-amino­ethane­sulfonato)-κ3 N,O:O′;κ3 O:N,O′]

The hydro­thermally prepared title compound, [Co(C2H6NO3S)2]n, is isotypic with its NiII analogue. The CoII cation is in a distorted octa­hedral environment, coordinated by four sulfonate O atoms and two N atoms from the taurine ligands. In comparison with the NiII analogue, the Co—N and Co—O bonds are longer than the Ni—N and Ni—O bonds, whereas all other bond lengths and angles as well as the hydrogen-bonding motifs are very similar in the two structures. The sulfonate groups doubly bridge symmetry-related CoII atoms, forming polymeric chains along the a axis. N—H⋯O hydrogen bonding interactions consolidate the crystal packing
