Helicity amplitudes for the small--angle process e^-e^{\pm}\to e^-γγ+ e^{\pm} with both photons along one direction and its cross channel

E. Kuraev, A. Schiller, V. Serbo +1

We study the small--angle double bremsstrahlung in $e^{-} e^{\pm}$ scattering for a jet kinematics where both photons move along the electron direction. This region gives the main contr…

Production of $e^{+} e^{-}$ pairs to all orders in $Z α$ for collisions of high-energy muons with heavy nuclei

D. Ivanov, E. A. Kuraev, A. Schiller +1

The $e^{+} e^{-}$ pair production in collisions of muon with atoms is considered to all orders in the parameter $Z α$ . We obtain energy distribution of $e^{+}$ and $e^{-}$ as well as energy…

Production of relativistic positronium in collisions of photons and electrons with nuclei and atoms

S. R. Gevorkyan, E. A. Kuraev, A. Schiller +2

We consider the production of ultrarelativistic positronium (Ps) in $γ A \to P s + A$ and $e A \to P s + e A$ processes where $A$ is an atom or a nucleus with charge $Z e$ . For the pho…

Helicity amplitudes for the small angle lepton pair production in e^+e^- or μ^+ μ^- collisions

E. A. Kuraev, A. Schiller, V. G. Serbo +1

The lepton pair production $e^{-} e^{+} \to e^{-} e^{+} l^{-} l^{+}$ or $μ^{-} μ^{+} \to μ^{-} μ^{+} l^{-} l^{+}$ is studied in the dominant cross section region of scattering angles ${m_j}/{E_j} \stack…
