Abstract
We study the order parameter distribution
P(q) in the 4d Ising spin glass with
couplings in a magnetic field. We also compare these results with simulations for the
infinite ranged model (i.e. SK model.) Then we analyse our numerical results in the framework
of the droplet picture as well as in the mean field approach.
