    ?-? mixing in chiral perturbation theory
    (World Scientific Publ Co Pte Ltd, 2006) Kucukarslan, Ayse; Meissner, Ulf-G.
    We investigate w-phi meson mixing to leading order in chiral perturbation theory utilizing the antisymmetric tensor field formulation. We update the quark mass ratio R from P-to mixing, R = 42 +/- 4.

    Strong CP violation in spin-1/2 singly charmed baryons
    (Springer Science and Business Media Deutschland GmbH, 2021) Ünal, Yasemin; Meissner, Ulf-G.
    We report on the calculation of the CP-violating form factor F3 and the corresponding electric dipole moment for charmed baryons in the spin-1/2 sector generated by the QCD θ-term. We work in the framework of covariant baryon chiral perturbation theory within the extended-on-mass-shell renormalization scheme up to next-to-leading order in the chiral expansion.
