Hyperons, Charm and Beauty Hadrons: Conclusion and Outlook
The subjects presented in the Conference [1] have in common their contribution to the understanding of the Flavour Problem ”from below”, i.e., from detailed studies of the structures, regularities and differences among the flavoured hadrons. In this edition, many new interesting results have been presented and my discussion will be necessarily limited in scope. I apologize for the omissions or ...
متن کاملStrangeness, Charm and Beauty in Hadrons
The talk is dedicated to spectroscopy of particles with heavy avours. A general overview of the current picture is given and several recent experimental results in this eld are discussed.
متن کاملWeak Radiative Decays of Hyperons and of Charm and Beauty Baryons *
A review is presented of the weak radiative decays of baryons. It includes an analysis of the possible contributions of electromagnetic penguins to these decays, a survey of the difficulties still encountered in the sector of hyperon decays and a short account on some new developments on this topic. The theoretical treatments on charm and beauty baryon decays are summarized, with a good outlook...
متن کاملDouble charm hadrons revisited
The dynamics of two heavy quarks inside the same hadron is probed against the double charm baryon results of SELEX. This can be seen as a part of the mechanism to bind tetraquarks with two heavy quarks and two light antiquarks. In the framework of potential models, it is possible to test the role of different effects: relativistic corrections, confinement, hyperfine forces, etc. It is conjectur...
متن کاملCharmonium singlets, open charm and exotic hadrons
The charmonium singlet states have resisted a firm identification for many years [1], but, now the ηc, η ′ c and hc are well identified. The mass of the latter, as given by the CLEOc collaboration is [2]m(hc) = 3524.4±0.6±0.4 MeV/c ,where the first uncertainty comes from statistics and the second one from estimated systematic errors. For the previous attempts and other measurements, see, e.g., ...
