Regularities in electromagnetic decay widths
We revisit Sakurai’s remark on the regularities of lepton-pair widths for mesons, extending the panorama to radiative X → γγ decays. The regularities persist, and somehow surprisingly some of them seem to relate with Fermi’s constant -or Z-. Back in 1978, Sakurai took the opportunity of a festscrift [11] to remark how the study of vector meson decays V → γ → ee, when extended to J/Ψ and Υ, seem...
متن کاملResonance trapping and saturation of decay widths
Resonance trapping appears in open many-particle quantum systems at high level density when the coupling to the continuum of decay channels reaches a critical strength. Here a reorganization of the system takes place and a separation of different time scales appears. We investigate it under the influence of additional weakly coupled channels as well as by taking into account the real part of th...
متن کاملDecay widths in the massive Schwinger model
By a closer inspection of the massive Schwinger model within mass perturbation theory we find that, in addition to the n-boson bound states, a further type of hybrid bound states has to be included into the model. Further we explicitly compute the decay widths of the three-boson bound state and of the lightest hybrid bound state. )permanent address: Inst. f. theoret. Physik d. Uni Wien Boltzman...
متن کاملGauge-Independent W -Boson Partial Decay Widths
We calculate the partial decay widths of theW boson at one loop in the standard model using the on-shell renormalization scheme endowed with a gauge-independent definition of the Cabibbo-Kobayashi-Maskawa (CKM) mixing matrix. We work in Rξ gauge and explicitly verify that the final expressions are independent of the gauge parameters. Furthermore, we establish the relationship between the on-she...
متن کاملSum Rule for Heavy Meson Decay Widths
A sum rule relating the widths of the decays of mesons belonging to heavy quark multiplets, having the same parity and light quark spin j, into the low lying 0 and 1 multiplet is obtained. As this sum rule follows from properties of the axial charges, it is protected from heavy quark spin dependent 1/mQ corrections. The sum rule works well for mesons containing a heavy charmed quark and, surpri...
