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…
Dependence of nucleon properties on pseudoscalar meson masses
Amand Faessler, Thomas Gutsche, Valery E. Lyubovitskij +1
We discuss the sensitivity of nucleon properties (mass, magnetic moments and electromagnetic form factors) on the variation of the pseudoscalar meson masses in the context of the p…
Hadronic atoms in QCD + QED
J. Gasser, V. E. Lyubovitskij, A. Rusetsky
We review the theory of hadronic atoms in QCD + QED, based on a non-relativistic effective Lagrangian framework. We first provide an introduction to the theory, and then describe s…
On the two-photon decay width of the sigma meson
Francesco Giacosa, Thomas Gutsche, Valery E. Lyubovitskij
We shortly report on the two-photon decay width of the light -meson interpreted as a quarkonium state. Results are given in dependence on the -mass and the constituent mass o…
D* K molecular structure of the Ds1(2460) meson
Amand Faessler, Thomas Gutsche, Valery E. Lyubovitskij +1
We discuss a possible interpretation of the Ds1(2460) meson as a hadronic molecule - a bound state of D* and K mesons. Using a phenomenological Lagrangian approach we determine the…
Role of the rho meson in the description of pion electroproduction experiments at JLab
Amand Faessler, Thomas Gutsche, Valery E. Lyubovitskij +1
We study the p(e,e' pi+)n reaction in the framework of an effective Lagrangian approach including nucleon, pi and rho meson degrees of freedom and show the importance of the rho-me…
Ds0*(2317) and Ds1(2460) mesons in two-body B-meson decays
Amand Faessler, Thomas Gutsche, Sergey Kovalenko +1
We analyze the branching ratios of B to D(*) + Ds0*(Ds1) decays using the factorization hypothesis. The B to D(*) transition form factors are taken from a model-independent analysi…
Strong and radiative decays of the Ds0*(2317) meson in the DK-molecule picture
Amand Faessler, Thomas Gutsche, Valery E. Lyubovitskij +1
We consider a possible interpretation of the new charm-strange meson Ds0*(2317) as a hadronic molecule - a bound state of D and K mesons. Using an effective Lagrangian approach we…
On the possible resolution of the B-meson decay polarization anomaly in R-parity violating SUSY
Amand Faessler, Thomas Gutsche, J. C. Helo +2
We examine the possible resolution of the recently observed polarization anomaly in B0(bar{B}0) -> phi K*0(bar{K}*0) decay within R-parity violating (RPV) SUSY. We show that a comb…
