In the present work one- and two-photon pair production in a subcritical magnetic field have been considered. Two-photon production has been studied in the resonant case, when the cross section considerably increases compared to the nonresonant case. While one-photon pair production is considered to be the main mechanism of plasma generation in a pulsar magnetosphere, we suggest the existence of another one, which is resonant two-photon production process.
We present numerical simulations of the electron-positron plasma creation process in a simple neutron star magnetosphere. We have developed a set of cascade `kernels, which represent the endpoint of the pair cascades resulting from monoenergetic phot
We reexamine the process $gammato e^++ e^-$ in a background magnetic field comparable to $B_cequiv m_e^2/e$. This process is known to be non-perturbative in the magnetic-field strength. However, it can be shown that the {it moments} of the above pair
We isolate the two-step mechanism involving a real intermediate photon from the one-step mechanism involving a virtual photon for the trident process in a constant crossed field. The two-step process is shown to agree with an integration over polaris
The process of neutrino production of electron positron pairs in a magnetic field of arbitrary strength, where electrons and positrons can be created in the states corresponding to excited Landau levels, is analysed. The mean value of the neutrino en
In this article, we have explored the very important quantity of lepton pair production from a hot and dense QCD medium in presence of an arbitrary magnetic field for simultaneous nonzero values of both the parallel and perpendicular components of mo
