Hadronic Molecules and the f0(980)/a0(980)
Tanja Branz, Thomas Gutsche, Valery E. Lyubovitskij
We discuss a possible interpretation of the f0(980) and a0(980) mesons as hadronic molecules - bound states of K and Kbar mesons. Using a phenomenological Lagrangian approach we ca…
Phenomenological Lagrangian approach to the electromagnetic deuteron form factors
Yubing Dong, Amand Faessler, Thomas Gutsche +1
A phenomenological Lagrangian approach is employed to study the electromagnetic properties of the deuteron. The deuteron is regarded as a weakly bound state of the proton and neutr…
Estimate for the X(3872) to gamma J/psi decay width
Yubing Dong, Amand Faessler, Thomas Gutsche +1
The X(3872) resonance is considered as a hadronic molecule, a loosely-bound state of charmed D0 and D*0 mesons, since its mass is very close to the D*0 barD0 threshold. Assuming st…
Molecular structure of the Bs0*(5725) and Bs1(5778) bottom-strange mesons
Amand Faessler, Thomas Gutsche, Valery E. Lyubovitskij +1
We discuss a possible interpretation of the scalar Bs0*(5725) and axial Bs1(5778) bottom-strange mesons as hadronic molecules - bound states of B K and B* K mesons, respectively. U…
Chiral corrections to the vector and axial couplings of quarks and baryons
Amand Faessler, Thomas Gutsche, Barry R. Holstein +1
We calculate chiral corrections to the semileptonic vector and axial quark coupling constants using a manifestly Lorentz covariant chiral quark approach up to order O(p4) in the tw…
f0(980) meson as a K bar K molecule in a phenomenological Lagrangian approach
Tanja Branz, Thomas Gutsche, Valery E. Lyubovitskij
We discuss a possible interpretation of the f0(980) meson as a hadronic molecule - a bound state of K and bar K mesons. Using a phenomenological Lagrangian approach we calculate th…
