Hadron Physics Opportunities at FAIR
J. G. Messchendorp, F. Nerling, P. Achenbach +103
This White Paper outlines a coordinated, decade-spanning programme of hadron and QCD studies anchored at the GSI/FAIR accelerator complex. Profiting from intense deuteron, proton a…
Estimates for rare three-body decays of the Omega baryon using chiral symmetry and the rule
Stefan Leupold, Cornelis J. G. Mommers
We study rare three-body decays of the Omega baryon using SU(3) chiral perturbation theory, the successful effective field theory of quantum chromodynamics at low energies. At lead…
Study of CP violation in hyperon decays at Super Charm-Tau Factories with a polarized electron beam
Nora Salone, Patrik Adlarson, Varvara Batozskaya +3
Non-leptonic two-body weak decays of baryons are an important tool to probe the combined charge-conjugation--parity symmetry (CP) violation. We explain why the decays of strange ba…
Spacelike zero crossings and timelike phases in the electromagnetic form factors of vector mesons
Stefan Leupold
Some form factors of ground-state hadrons with spin might show a zero crossing at spacelike momenta of electron-hadron scattering. In the timelike region of hadron-antihadron produ…
Sum rule for the partial decay rates of bottom hadrons based on the dynamical supersymmetry of the quark and the diquark
Taiju Amano, Daisuke Jido, Stefan Leupold
We investigate the weak decays of and to charm hadrons based on the dynamical supersymmetry between the quark and the diquark. We derive a ne…
Electromagnetic transition form factors and Dalitz decays of hyperons
Stefan Leupold, Nora Salone
Dalitz decays of a hyperon resonance to a ground-state hyperon and an electron-positron pair can give access to some information about the composite structure of hyperons. We prese…
