Point-Form Quantum Field Theory and Meson Form Factors
Recently we have reconsidered the quantization of relativistic field theories on a Lorentz-invariant surface of the form xμx μ = τ [1]. With this choice of the quantization surface all components of the 4-momentum operator become interaction dependent, whereas the generators of Lorentz transformations stay free of interactions – a feature characteristic for Dirac’s “point form” of relativistic ...

متن کاملElastic Form Factors in Point-form Approach
Using the point-form approach to relativistic quantum mechanics, a covariant framework is presented for the calculation of proton and neutron electromagnetic form factors. Results for charge radii, magnetic moments, and electric as well as magnetic form factors are produced using the wave functions obtained in the socalled Goldstone-boson-exchange constituent quark model. All the predictions ar...
متن کاملStructure of the rho meson and the pion form-factor
From the electromagnetic form factor of the pion and from the decay modes of the τ lepton involving two or three pions one can see that the isovector–vector quark current couples strongly to the ρ meson whereas the isovector– axial-vector current couples strongly to the a1. Therefore such reactions provide excellent access to studies of the properties of (axial-)vector mesons. It has been shown...
متن کاملForm Factors in D Meson Decays
We study the dΓ/dq spectra and the branching fractions of the D meson exclusive semileptonic decays with the lepton mass effects into consideration. We investigate their sensitivity to form factor models, and find that the decays to a pseudoscalar meson and a lepton pair are sensitive to the property of the form factor F1(q ), and those to a vector meson and a lepton pair to the form factor A1(...
