This theory describes all scattering properties, including medium effects, in terms of the singlet and triplet scattering lengths and the range of the atom-atom potential and provides a link between a microscopic description of Feshbach scattering and more phenomenological approaches. It permits the calculation of medium effects on the resonance coming from the occupation of closed channel states. The examination of such effects is demonstrated to be of particular relevance to an experimentally important Feshbach resonance for 40K atoms. We analyze a recent rethermalization rate experiment on 40K and demonstrate that a measurement of the temperature dependence of this rate can determine the magnetic moment of the Feshbach molecule. Finally, the energy dependence of the Feshbach interaction is shown to introduce a negative effective range inversely proportional to the width of the resonance. Since our theory is based on a microscopic multichannel picture, it allows the explicit calculation of corrections to commonly used approximations such as the neglect of the effective range and the treatment of the Feshbach molecule as a point boson Kategória publikačnej činnosti ADC Číslo archívnej kópie 26412 Kategória ohlasu ZHU, Shangguo - TAN, Shina.

We demonstrate that by the field redefinition some models can be equivalently transformed into each other. Thereby the large variety of scaling functions for masses and couplings can be reduced to a restricted set of functions with a constrained dependence on a scalar field. We show how by choosing properly the latter scaling functions one may stiffen or soften the equation of state at high densities and simultaneously increase the threshold density for the direct Urca process without any change of the description of nuclear matter close to the saturation density. The stiffening of the equation of state might be motivated by recent neutron star mass measurements, whereas the increase of the threshold density for the direct Urca process (n(crit)(DU)) is motivated by the analysis of neutron star cooling data. The high value n(crit)(DU) also follows from the variational calculations of the A18 + delta v + UIX* Urbana-Argonne model. We demonstrate that if a rho meson is included in a mean-field model as a non-Abelian gauge boson, then there is a possibility for a charged rho-meson condensation in dense nuclear matter. We show that such a novel phase can be realized in neutron star interiors already for sufficiently low densities, typically similar to 3-4n(0), where no is the nuclear saturation density. In the framework of the relativistic mean field model the new phase arises in a second-order phase transition. The appearance of a rho(-) condensate significantly alters the proton fraction in a neutron star but changes moderately the equation of state. The neutrino emissivity of the processes involving a rho(-) meson condensate is estimated Kategória publikačnej činnosti ADC Číslo archívnej kópie 26415 Kategória ohlasu VOSKRESENSKAYA, M.

Based on the leading order term of the chiral Lagrangian a rich spectrum of molecules is generated, owing to final-state interactions. The spectrum of s- and d-wave baryon states with zero and non-zero charm is remarkably consistent with the empirical pattern. In particular, the recently announced Σc(2800) of the BELLE collaboration is reproduced with realistic mass and width parameters. Similarly, the dwave states Λc(2625) and Ξc(2815) are explained naturally as chiral excitations of JP = 3 2 + states. In the open-charm sector exotic multiplet structures are predicted. These findings support a radical conjecture: meson and baryon resonances that do not belong to the large-Nc ground state of QCD should be viewed as hadronic molecular states Kategória publikačnej činnosti ADC Číslo archívnej kópie 26410 Katal.org.
