Energy radiated from a fluctuating selfdual string

Journal article, 2005

We compute the energy that is radiated from a fluctuating selfdual string in the large-N limit of AN-1 theory using the AdS-CFT correspondence. We find that the radiated energy is given by a non-local expression integrated over the string world-sheet. We also make the corresponding computation for a charged string in six-dimensional classical electrodynamics, thereby generalizing the Larmor formula for the radiated energy from an accelerated point particle.
