Theoretical physics of fundamental interactions



The LHC_b collaboration has just reported the first observation of Ω_𝑏 states b states (in " First observation of excited Ω_𝑏 states”, LHCb Collaboration (Roel Aaij et al.). Jan 3, 2020, arXiv:2001.00851 [hep-ex]). Those excited Ω_b states have been theoretically predicted in E. Santopinto et al., Eur.Phys.J. C79 (2019) no.12, 101 considering the symmetries of the strong interaction. The idea of this thesis is to give predictions also for other heavy-flavored baryons with two b quarks ( i.e Ξbb = qbb , Ωbb=sbb ) - that have still to be explored by the experimentalists and for which there are still not theoretical predictions based on symmetries - and to extend the predictions to other heavy-flavored baryons with one single b quark, that is Λb,Σb, Ξb ,Ξ'b. All those theoretical predictions are of interest to the LHCb-collaboration, which is also present at Genoa University.
