Low-energy Universality and the New Charmonium Resonance at 3870 MeV
Eric Braaten, Masaoki Kusunoki
The recently-discovered narrow charmonium resonance near 3870 MeV is interpreted as a hadronic molecule whose constituents are the charm mesons D^0 and \bar D^{*0} or \bar D^0 and…
An Infrared Renormalization Group Limit Cycle in QCD
Eric Braaten, H. -W. Hammer
We conjecture that QCD can be tuned to an infrared limit cycle in the three-nucleon system by adjusting the up and down quark masses to critical values at which the binding energie…
Lambda_c^+/Lambda_c^- Asymmetry in Hadroproduction from Heavy-Quark Recombination
Eric Braaten, Masaoki Kusunoki, Yu Jia +1
Asymmetries in the hadroproduction of charm particles directly probe power corrections to the QCD factorization theorems. In this paper, the heavy-quark recombination mechanism, a…
An Infrared Renormalization Group Limit Cycle in QCD
Eric Braaten, H. -W. Hammer
Small increases in the up and down quark masses of QCD would tune the theory to the critical renormalization group trajectory for an infrared limit cycle in the three-nucleon syste…
Enhanced Dimer Relaxation in an Atomic/Molecular BEC
Eric Braaten, H. -W. Hammer
We derive a universal formula for the rate constant βfor relaxation of a shallow dimer into deeply-bound diatomic molecules in the case of atoms with a large scattering length a. W…
Comment on ``Ramsey Fringes in a Bose-Einstein Condensate between Atoms and Molecules''
Eric Braaten, H. -W. Hammer, M. Kusunoki
In Phys. Rev. Lett. 89, 180401 (2002) [cond-mat/0204504], Kokkelmans and Holland interpret the results of a recent experiment at JILA that demonstrated atom-molecule coherence in a…
