Abstract
The minimal energy variations of a directed polymer with tilted columnar di sorder in two dimensions are shown numerically to obey multiscaling at shor t distances which crosses over to global simple scaling at large distances. The scenario is analogous to that of structure functions in bifractal Burg ers turbulence. Some scaling properties are predicted from extreme value st atistics. The multiscaling disappears for zero tilt.
