Elastic 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 کاملPoint-form Approach to Baryon Structure
A critical discussion is given of the results for baryon electromagnetic and axial form factors obtained from relativistic constituent quark models in the framework of Poincaré-invariant quantum mechanics. The primary emphasis lies on the point-form approach. First we summarize the predictions of the Goldstone-bosonexchange constituent quark model for the electroweak nucleon structure when usin...
متن کاملPoint-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 کاملDirac ’ s inspired point form and hadron form factors
Noticing that the " point-form " approach referred to in many recent works implies physics described on hyperplanes, an approach inspired from Dirac's one, which involves a hyperboloid surface, is presented. A few features pertinent to this new approach are emphasized. Consequences as for the calculation of form factors are discussed.
متن کاملHow everyday language can and will boost effective information retrieval
Typing two or three keywords into a browser has become an easy and efficient way to find information. Yet, typing even short queries becomes tedious on ever shrinking (virtual) keyboards. Meanwhile, speech processing is maturing rapidly, facilitating everyday language input. Also, wearable technology can inform users proactively by listening in on their conversations or processing their social ...
