Light-front potential for heavy quarkonia constrained by the holographic soft-wall model
Thomas Gutsche, Valery E. Lyubovitskij, Ivan Schmidt +1
We derive a light-front Schrodinger-type equation of motion for the quark-antiquark wave function of heavy quarkonia imposing constraints from the holographic soft-wall model.
Nucleon structure in a light-front quark model consistent with quark counting rules and data
Thomas Gutsche, Valery E. Lyubovitskij, Ivan Schmidt +1
Using global fits of valence u and d quark parton distributions and data on quark and nucleon form factors in the Euclidean region, we derive a light-front quark model for the nucl…
Radiative and dilepton decays of the hadronic molecule Zc(3900)+
Thomas Gutsche, Matthias Kesenheimer, Valery E. Lyubovitskij
The newly observed hidden-charm meson Zc(3900) with quantum numbers J(P) = 1(+) is considered as a hadronic molecule composed of DD*. We give detailed predictions for the decay mod…
Heavy-to-light semileptonic decays of Lambda_b and Lambda_c baryons in the covariant confined quark model
Thomas Gutsche, Mikhail A. Ivanov, Jurgen G. Korner +2
We present a detailed analysis of the heavy-to-light semileptonic decays of the Lambda_b and Lambda_c baryons Lambda_b -> p l- bar(nu)_l and Lambda_c -> n l+ nu_l in the covariant…
On the meson mass spectrum in the covariant confined quark model
Gurjav Ganbold, Thomas Gutsche, Mikhail A. Ivanov +1
We provide a new insight into the problem of generating the hadron mass spectrum in the framework of the covariant confined quark model. One of the underlying principles of this mo…
The effect of multi-channel pion-pion scattering in decays of the -family mesons
Yu. S. Surovtsev, P. Bydzovsky, T. Gutsche +3
The effect of isoscalar S-wave multi-channel pion-pion scattering () is considered in the analysis of data on decays of the -meson family -- $Υ(2S)\toΥ(1S)π…
Pion light-front wave function, parton distribution and the electromagnetic form factor
Thomas Gutsche, Valery E. Lyubovitskij, Ivan Schmidt +1
We derive the lowest-order valence light-front wave function for the pion with Lz=0 and |Lz|=1, which reproduces its valence parton distribution and the electromagnetic f…
Role of the hadron molecule Lambda_c(2940) in the p bar(p) -> p D0 bar(Lambda)_c(2286) annihilation reaction
Yubing Dong, Amand Faessler, Thomas Gutsche +1
The annihilation process p bar(p) -> p D0 bar(Lambda)_c(2286) is studied taking into account t-channel D0, D*0 meson exchange and the resonance contribution of Lambda_c(2286) and L…
Radiative decay Y(4260) -> X(3872) + gamma involving hadronic molecular and charmonium components
Yubing Dong, Amand Faessler, Thomas Gutsche +1
We apply a phenomenological Lagrangian approach to the radiative decay Y(4260) -> X(3872) + gamma. The Y(4260) and X(3872) resonances are considered as composite states containing…
