Eta-mesic nuclei: past, present, future
Q. Haider, L. C. Liu
Eta-mesic nucleus or the quasibound nuclear state of an eta () meson in a nucleus is caused by strong-interaction force alone. This new type of nuclear species, which extends th…
Eta-Mesic Nucleus and COSY-GEM Data
Q. Haider, L. C. Liu
The experimental data of the COSY-GEM Collaboration for the recoil-free transfer reaction p (27Al, 3He) π- p' X, leading to the formation of bound state of eta (η) meson in 25Mg nu…
Interference and nuclear medium effects on the eta-mesic nuclear spectrum
Q. Haider, Lon-chang, Liu
The missing-mass spectrum obtained in a recoil-free transfer reaction p(Al,He)p'X is analyzed. We find that the observed peak structure arises from the coherent…
Eta-Mesic Nucleus: A New Form of Nuclear Matter
Q. Haider, L. C. Liu
Formation of eta-mesic nucleus, a bound state of an eta meson in a nucleus, is reviewed in this paper. Three different theoretical approaches are used to calculate the binding ener…
Dependence of calculated binding energies and widths of -mesic nuclei on treatment of subthreshold -nucleon interaction
Q. Haider, L. C. Liu
We demonstrate that the binding energies and widths of eta-mesic nuclei depend strongly on subthreshold eta-N interaction. This strong dependence is made evident from comparing thr…
Pionic Content of Rho-N-N and Rho-N-Delta Vertex Functions
Q. Haider, L. C. Liu
The dynamical content of rho-N-N and rho-N-Delta vertex functions is studied with a mesonic model. A set of coupled integral equations satisfied by these vertex functions were solv…
