Double 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 کاملHADRONS ABOVE Tc
Fate of light hadronic excitations above the critical temperature Tc of the QCD phase transition was first investigated 20 years ago.1,2 In Ref. 1 whose title is “Fluctuation effects in hot quark matter: precursors of chiral transition at finite temperature”, the hadrinic modes above Tc were discussed in connection with the critical fluctuation associated with chiral symmetry restoration: The a...
متن کاملNew states above charm threshold
In the short time since the Belle Collaboration reported sighting the “missing” charmonium state η c(2 S0) in exclusive B → KKSK π decays [1], new states associated with charmonium have appeared in great profusion. Apart from the long-sought hc(1 P1), recently observed by the CLEO Collaboration in the decay ψ(2S) → πhc → (γγ)(γηc) [2, 3], all the newly observed states lie near or above charm th...
متن کاملSemileptonic decays of the bottom-charm hadrons
We present the results of a study of the semileptonic decays of the Bc-meson and the lowest lying doubly heavy baryons using the relativistic quark model. We do not employ a heavy quark mass expansion but keep the masses of the heavy quarks and hadronss finite. We calculate all relevant form factors and decay rates. The semileptonic decays of heavy mesons and baryons are ideally suited to extra...
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.
