Abstract We use the method of light-cone sum rules to study decay properties of P-wave bottom baryons belonging to the SU(3) flavor $$\mathbf {6}_F$$6F representation. In Cui et al. (Phys Rev D 99:094021, 2019) we have studied their mass spectrum and pionic decays, and found that the $$\varSigma _{b}(6097)$$Σb(6097) and $$\varXi _{b}(6227)$$Ξb(6227) can be well interpreted as P-wave bottom baryons of $$J^P = 3/2^-$$JP=3/2-. In this paper we further study their decays into ground-state bottom baryons and vector mesons. We propose to search for a new state $$\varXi _b({5/2}^-)$$Ξb(5/2-), that is the $$J^P = 5/2^-$$JP=5/2- partner state of the $$\varXi _{b}(6227)$$Ξb(6227), in the $$\varXi _b({5/2}^-) \rightarrow \varXi _b^{*}\rho \rightarrow \varXi _b^{*}\pi \pi $$Ξb(5/2-)→Ξb∗ρ→Ξb∗ππ decay process. Its mass is $$12 \pm 5$$12±5 MeV larger than that of the $$\varXi _{b}(6227)$$Ξb(6227).

Isotope Chain

The ground state properties of Hs nuclei were studied to give an overview to the isotope chain. It is seen that more stable isotopes are located on the proton abundant side of the chain. The last stable nucleus to the proton drip line is 256 Hs . The most stable unknown Hs nucleus may be 268 Hs . The proton Fermi surfaces of Hs nuclei are close to zero, the conventional BCS treatment with constant pairing interaction can excite protons to the continuum, and causes the failure for pairing correction. The density dependent delta interaction results in more reasonable single-particle energy level distributions and nucleon occupation. Therefore it has improved the BCS treatment, and is available to describe the properties of nuclei in the superheavy region.

Good Agreement

Levels in the nucleus 25Mg have been studied by measurement of the angular distributions and polarization of gamma rays from the 22Ne(α, nγ)25Mg reaction. Information regarding spins, parities, mixing ratios, and branching ratios has been obtained for the levels between 2.7 and 4.7 MeV excitation. Spin and parity assignments of 5/2+ and 7/2− have been made to the levels at 3.90 and 3.97 MeV. Mixing ratios have been determined or restricted for most of the observed transitions. The decay branch of the 3.40 MeV level to the ground state is found to be considerably stronger than previously reported, bringing the decay properties of this level into good agreement with the predictions of the simple rotational model. The significance of the results within the framework of the rotational model is discussed. There is evidence for considerable band mixing in levels belonging to the second Kπ = 1/2+ and the Kπ = 1/2− bands.

The phenomenon of bioluminescence has fascinated layman and scientist alike for many centuries. During the eighteenth and nineteenth centuries a number of observations were reported on the physiology of bioluminescence in Renilla, the common sea pansy. More recently biochemists have directed their attention to the molecular basis of luminosity in this colonial form. These studies have centered primarily on defining the chemical basis for bioluminescence and its control. It is now established that bioluminescence in Renilla arises due to the luciferase-catalyzed oxidation of luciferin. This results in the creation of a product (oxyluciferin) in an electronic excited state. The transition of oxyluciferin from its excited state to the ground state leads to light emission.
