New Quadratic Baryon Mass Relations
By assuming the existence of (quasi)-linear baryon Regge trajectories, we derive new quadratic Gell-Mann–Okubo type baryon mass relations. These relations are used to predict the masses of the charmed baryons absent from the Baryon Summary Table so far, in good agreement with the predictions of many other approaches.

متن کاملQuark mass dependence of baryon properties
I discuss the quark mass dependence of various baryon properties derived from chiral perturbation theory. Such representations can eventually be used as chiral extrapolation functions when lattice data at sufficiently small quark masses become available. The quark mass dependence is encoded in loop and contact term contributions, the latter given in terms of low-energy constants. I stress the i...
متن کاملBaryon Crisis and Cluster Mass Estimates
I report the current status on the determinations of the baryon fractions and dynamical/lensing masses of galaxy clusters as well as the σ T relationship, making use of all the published data in literature which include 304 measurements for baryon fractions, 320/21 data points for masses of intracluster gas/cluster galaxies, (152+228)/72 data points for cluster masses derived from X-ray emittin...
متن کاملUpdate of Heavy Baryon Mass Predictions
Predictions of unknown heavy baryon masses based on an expansion in 1/mQ, 1/Nc and SU(3) breaking are updated to take into account a recent measurement of the Σc mass. Values are given for the two remaining unknown charm baryon masses Ξc and Ω ∗ c and the seven unknown bottom baryon masses Ξb, Σb, Ξ ′ b, Ωb, Σ ∗ b , Ξ ∗ b and Ω ∗ b . The spectrum of baryons containing a single charm or bottom q...
