Open superstring first mass level effective Lagrangian: Massive spin-2 in an electromagnetic background
Minimal coupling leads to problems such as loss of causality if one wants to describe charged particles of spin greater than one propagating in a constant electromagnetic background. Regge trajectories in string theory contain such states, so their study may allow us to investigate possible avenues...
