Abstract
We calculate the photon pair production rate in a strong magnetic field created in off-central heavy-ion collisions. Photon decay leads to depletion of the photon yield by a few percent at RHIC and by as much as 20% at the LHC. It also generates a substantial azimuthal asymmetry (``elliptic flow'') of the final photon distribution. We estimate ${v}_{2}\ensuremath{\approx}2$% at RHIC and ${v}_{2}\ensuremath{\approx}14$% at LHC. Photon decay measurements is an important tool for studying the magnetic fields in early stages of heavy-ion collisions.
