It should be noted that the Landau distribution has no free parameters! Thus, the curve in the figure is wrong. There is no Landau distribution with a most probable value of 2 and a $\sigma$ of 1. Actually the most probable value is (ROOT TMath::Landau()) around 0.222.
Just by scaling and shifting one can introduce artificially a most probable value and a width

$x\rightarrow \frac{x-MPV}{\sigma}-0.222$

The physics of high energy ionized particles going through a thin piece of material

Deserves its own page too, and link back and forth.82.171.225.84 (talk) 21:09, 16 August 2011 (UTC)

Derivation

Could someone who knows add a section on why this is the distribution of particles' energy loss travelling through a thin medium?
