Abstract
Neutrinos participate in charged current reactions which are mediated by W bosons and
in neutral current reactions mediated by Z0 bosons. The latter process allowed us to count
the number of light neutrino species that have the usual electroweak interaction. In this
work we examine electron-positron pair production with neutrinos in an intense laser eld
through the process -ve-e+. We rst review GWS model for electroweak interactions
and the process -v1e+ which proceeds through neutral channel. We also treat this
process through charged channel. Of course the process through the charged channel is
relevant only for electron neutrino. A detailed calculation of these processes is carried
out. For the charged current reaction the rate of electron-positron pair production is
calculated, using the same procedure we do for the reaction through the neutral channel.
Finally a tabulation of the rate of production for di erent neutrino energies is presented
for the neutral current reaction. We also present graphs to show the variation of rate with
the number of photons extracted from the laser eld to run the reaction
