We review the weak-decay and spectroscopy properties of baryons with two charmed quarks. We also present the convergent speculations on exotic mesons $(QQ\bar{q}\bar{q})$ with two heavy quarks and two light antiquarks.

Spectroscopy of doubly-charmed baryons in lattice QCD
We present results for masses of spin-1/2 and spin-3/2 double-charm baryons in quenched lattice QCD, from an exploratory study using a non-perturbatively improved clover action at ?=6.2. We have
Double heavy baryons and dimesons
Abstract.We critically examine the question whether the cc$\bar{{\rm q}}\bar{{\rm q}}$ dimeson is bound or not.
THE PENTAQUARKS IN THE LINEAR MOLECULAR HEPTAQUARK MODEL
In this talk, multiquarks are studied microscopically in a standard quark model. In pure ground-state pentaquarks the short-range interaction is computed and it is shown to be repulsive. An
Exotic pentaquarks, crypto-heptaquarks and linear three-hadronic molecules
In this talk, multiquarks are studied microscopically in a standard quark model. In pure ground-state pentaquarks the short-range interaction is computed and it is shown to be repulsive, a narrow

Very charming baryons
The multiply charmed baryons have a very interesting spectroscopy and provide a unique laboratory for studying the strong interaction dynamics that bind quarks into hadrons. We wish to point out that
Spectra of baryons containing two heavy quarks
The spectra of baryons containing two heavy quarks test the form of the $QQ$ potential through the spin-averaged masses and hyperfine splittings. The mass splittings in these spectra are calculated
Interactions between heavy-light mesons in lattice QCD
A potential between heavy-light mesons is extracted from quark correlation functions in the framework of quenched lattice QCD with Kogut-Susskind fermions. We show that the resulting potential is
Stability of Multiquark Systems
We give a brief review of developments in the field of exotic hadrons formed of more than three quarks and/or antiquarks. In particular we discuss the stability of multiquark systems containing heavy
Hadrons with a heavy color-adjoint particle
We discuss the spectrum of hadrons with a heavy colour-adjoint particle - motivated by the gluino of supersymmetry. Using the lattice approach, we explore in detail the gluonic bound states - the
Weak Interactions with Lepton-Hadron Symmetry
We propose a model of weak interactions in which the currents are constructed out of four basic quark fields and interact with a charged massive vector boson. We show, to all orders in perturbation
Spectroscopy of doubly heavy baryons
Within a nonrelativistic quark model featuring a QCD-motivated Buchmüller-Tye potential, the mass spectra for the families of doubly heavy baryons are calculated by assuming the quark-diquark
Predicting the masses of baryons containing one or two heavy quarks.
The Feynman-Hellmann theorem and semiempirical mass formulas are used to predict the masses to baryons containing one or two heavy quarks. In particular, the mass of the {Lambda}{sub {ital b}} is
Comment on `First observation of doubly charmed baryon Xi(cc)+'
We speculate on a possible interpretation of events selected by the SELEX collaboration and stress an insufficient evidence for the observation of doubly charmed baryon.
Charmed baryon lifetime differences
We predict the quantitative lifetime differences of weakly decaying charmed baryons which arise due to preasymptotic bound state effects. These predictions are to a large extent model independent. We
