Double heavy tri-hadron bound state via delocalized π bond

New π-Delocalized Persistent Radicals

Progress in the theoretical and experimental investigation of heterocyclic radicals suitable for incorporation into the structure of a liquid crystalline molecule is described. Five classes of heterocyclic systems are discussed, including their methods of preparation, stability and further functionalization to form potentially mesogenic materials. Introduction Over the past decade, we have been...

Final State Interaction in Heavy Hadron Decay

Though nothing is known for B → ππ,Kπ,KK, we might conjecture that the FSI phases diminish as the initial mass increases. Meanwhile the relative FSI phase is known for the ggg and ”γ” decay amplitudes of the J/ψ decays: 3 ∆δ ≈ 90 and 75 for J/ψ → 00 and 01, respectively. Therefore, if the FSI phases diminish with the increasing initial mass, it should start diminishing somewhere between mJ/ψ an...

Bound-state effects on gluino-pair production at hadron colliders

We study bound-state effects on the pair production of gluinos at hadron colliders, in a context of the minimal supersymmetric extension of the standard model. Due to the expected large mass and the octet color-charge of gluinos, the bound-state effects can be substantial at the LHC. We find significant deformation of the invariant-mass distributions of a gluino-pair near the mass threshold, as...

Heavy Hadron Spectroscopy

After having played a major role in the foundation of QCD, heavy hadron spectroscopy has witnessed in the last years a renewal of interest led by the many new data coming from the B factories, CLEO and the Tevatron and by the progress made in the theoretical methods. I will summarize the former and mostly focus on the latter. Much of the theoretical progress in the physics of heavy hadrons come...
