Ultraviolet and infrared freedom from string amplitudes
The infinite tension limit of string amplitudes is examined with some care, identifying the part responsible of diamagnetic behaviour as well as a peculiar paramagnetic {\em tachyon magnifying} responsible of aysmptotic freedom. The way string theory represents abelian gauge theories is connected wi...
