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 field through the process ν ! ν0e−e+. We first review GWS model for electroweak interactions and the process ν ! ν0e−e+ 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 different 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 field to run the reaction.
