MOMENTUM DISTRIBUTIONS IN tt̄ PRODUCTION AND DECAY NEAR THRESHOLD (II): MOMENTUM DEPENDENT WIDTH
We apply the Green function formalism for t − t̄ production and decay near threshold in a study of the effects due to the momentum dependent width for such a system. We point out that these effects are likely to be much smaller than expected from the reduction of the available phase space. The Lippmann–Schwinger equation for the QCD chromostatic potential is solved numerically for S partial wave...
متن کاملFinite width effects and gauge invariance in radiative W production and decay.
The naive implementation of finite width effects in processes involving unstable particles can violate gauge invariance. For the example of radiative W production and decay, qq̄ → lνγ, at tree level, it is demonstrated how gauge invariance is restored by including the imaginary part of triangle graphs in addition to resumming the imaginary contributions to the W vacuum polarization. Monte Carlo ...
متن کاملFinite width effects in φ radiative decays
The decay widths φ → γf0(980) and φ → γa0(980) are calculated taking into account the finite widths of the scalar resonances f0(980) and a0(980). The latter are shown to be essential in order to obtain meaningful results. Simultaneously we also study the decays φ → γππ and γπη where a good reproduction of the recent experimental data is obtained, pointing out the necessity of a φγKK̄ contact ver...
متن کاملPion-pion scattering near threshold in the Resonance-Spectrum Expansion
We study the properties of the Resonance-Spectrum Expansion near threshold in I = 0 S-wave ππ scattering. The real part of the amplitude, when extrapolated from above threshold to below threshold, is found to vanish at a positive non-zero value of the total invariant mass of the system, in agreement with predictions from perturbative chiral models. In our exact analytic expression, the total am...
متن کاملEffects of finite pulse width on two-dimensional Fourier transform electron spin resonance.
Two-dimensional (2D) Fourier transform ESR techniques, such as 2D-ELDOR, have considerably improved the resolution of ESR in studies of molecular dynamics in complex fluids such as liquid crystals and membrane vesicles and in spin labeled polymers and peptides. A well-developed theory based on the stochastic Liouville equation (SLE) has been successfully employed to analyze these experiments. H...
