An investigation of triply heavy baryon production at hadron colliders
The triply heavy baryons have a rather diverse mass range. While some of them possess considerable production rates at existing facilities, others need to be produced at future high energy colliders. Here we study the direct fragmentation production of the Ωccc and Ωbbb baryons as the prototypes of triply heavy baryons at the hadron colliders with different √ s. We present and compare the trans...
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...
متن کاملThe heavy quark potential in pNRQCD
In a recent series of papers [1,2] a detailed study of a suitable Effective Field Theory for heavy quark bound states, called potential NRQCD (pNRQCD) [3], has been started. Since several issues have been treated in that context, we address the reader to the quoted literature for a complete overview of the achieved results. Here we only mention the 1-loop matching [4] and the static energies of...
متن کاملConstituent-quark model description of triply heavy-baryon nonperturbative lattice QCD data
This paper provides results for the spectra of triply charmed and bottom baryons based on a constituent quark model approach. We take advantage of the assumption that potential models are expected to describe triply heavy baryons to a similar degree of accuracy as the successful results obtained in the charmonium and bottomonium sectors. The high precision calculation of the ground state and po...
متن کاملUnitarized pion-nucleon scattering within Heavy Baryon Chiral Perturbation Theory
By means of the Inverse Amplitude Method we unitarize the elastic pion-nucleon scattering amplitudes obtained from Heavy Baryon Chiral Perturbation Theory to O(q3). Within this approach we can enlarge their applicability range and generate the ∆(1232) resonance. We can find a reasonable description of the pion nucleon phase shifts with O(q2) parameters in agreement with the resonance saturation...
