• W1819682006 abstract "Baryons containing two heavy quarks are important and interesting systems to study the quark-diquark structure of baryons and to understand the dynamics of QCD at hadronic scale. The Selex Collaboration has recently reported the discovery of Ξcc with a mass of 3.519 GeV . However, other groups such as Babar , Belle and Focus have all failed to confirm this state. So there is a demand to review this state both theoretically and experimentally. We report here the spectra and magnetic moments of ccq(q ∈ u, d, s) systems using coulomb plus Martin potential. Here the two heavy quarks are considered for the diquark states. The same potential form is used for the diquark interaction as well as for the quark-diquark interaction. The chromomagnetic one gluon exchange interaction are perturbatively treated here to get the masses of JP = 12 + and JP = 32 + states. Accordingly, we obtain Ξ++ cc (3519, 3555), Ξ + cc (3527, 3562) and Ωcc (3648,3688) states of the ccq ( 1 2 + , 32 + ) combinations. Our predictions are in accordance with the selex result for Ξ++ cc (3519) and other model predictions. Predictions of other properties of these ccq systems will be presented in detail. Introduction The first observation of B+ c meson by the CDF collaboration [1] opens a new direction in the physics containing heavy quarks. This particle completes the list of heavy QQ mesons accessible for the experimental investigations. It begins another list of hadrons containing two heavy quarks. The investigation of properties of hadrons containing heavy quarks is of great interest in understanding the dynamics of QCD at the hadronic scale. Though the experimental and theoretical data on the properties of heavy flavour mesons are available plenty in literature, the masses of most of the heavy baryons have not been measured yet experimentally [2]. Thus the recent predictions about the heavy baryon mass spectrum have become a subject of renewed interest due to the experimental facilities at Belle, BABAR, DELPHI, CLEO, CDF etc [3, 4, 5, 6, 7, 8]. These experimental groups have been successful in discovering heavy baryonic" @default.
