Pair production and heavy electron

Zeitschrift f�r Physik, 1966
Production of electron positron pairs is analysed with the hypothesis of the heavy electrone *. A rough agreement between theory and experiment is found if the coupling constant is suitably chosen as a function of the massm * of thee *. Comparison with upper limits for this coupling constant taken from inelastic electron proton scattering indicates ...

Microfluidic Production of Droplet Pairs

Langmuir, 2008
We study a microfluidic dual nozzle for the production of water-in-oil droplet pairs. Droplets are paired by the hydrodynamic coupling of two nozzles over a wide range of aqueous and oil flow rates provided that they are larger than the channel dimensions.

Production of Electron Pairs

Nature, 1936
SOME time ago we described a method1 for calculating rigorously (neglecting screening) the cross–section for production of electron–positron pairs in the field of a nucleus by a beam of γ–rays. This method also gave the energy distribution of the electrons or positrons.

Pair Production by Photons

Reviews of Modern Physics, 1969
This paper reviews, analyzes, and integrates the various quantitative results that have been obtained for the process of pair production by photons. Included in this summary is a detailed review of total and differential cross sections for pair production in an atomic and in an electron field, with a critical evaluation of the conditions of validity ...

Pair production by pions

Journal of Physics G: Nuclear Physics, 1977
The process pi -p to ne+e- is analysed in terms of the polarisation of the virtual photon involved as is normal in pion electroproduction. The PCAC approach to pion photoproduction and electroproduction can then be applied directly to this process.

Production of Electron Pairs [PDF]

Nature, 1935
DIRAC's theory of electrons gives us tho possibility of calculating the production of electronic pairs by collisions between electrons and nuclei. This process may be described as a second order effect of the porturbation of plane electron waves due to the nuclear field, and to the interaction between the incident electron and the electron which ...

Pair production in transport equations

Physical Review D, 1988
In the study of quark-gluon systems using transport equations, the production of quarks and antiquarks is often introduced in the form of a source term based on the Schwinger formula for pair production in the presence of a constant (color-)electric field.
