| Research Abstract |
We proposed measurement of anisotropy and polarization of direct virtual photons via di-electron decay channel, aiming at direct detection of intense magnetic field production in high energy nucleus-nucleus collisions. Polarization measurement of virtual photons has been accomplished at RHIC-PHENIX and LHC-ALICE experiments. Detection of intense magnetic field production has been pursued, via geometrical correlation measurement and analysis of di-electron decay anisotropy with event-by-event three-dimensional collision geometry. Feasibility of intense magnetic field detection at these experiments has been clarified, with a quantitative estimation of the expected anisotropy and polarization in theenergy regions at RHIC and LHC accelerators, by numerical calculations based on Quantum Electromagnetic-Dynamics.
