comment Classical lagrangian spin SU(2)
The energy for the interaction of a classical spin with a magnetic field is $E=\vec{\mu}\cdot\vec{B}$. If you normalize the magnetic moment $\vec{\mu}=\mu\vec{\sigma}$ where $\vec{\sigma}$ is indeed an element of $S^2$.

comment Classical lagrangian spin SU(2)
But who is saying that the model you wrote down is for a "classical" spinning particle? I don't agree.

comment Classical lagrangian spin SU(2)
Your question is not quite clear. What do you want to know about the model? It seems to be a semi-classical model in the sense that the particle trajectory is treated classically, but the spin is treated quantum mechanically. Is it maybe the Lagrangian for the Stern-Gerlach experiment?

comment Fokker Plank EQUATION
The Fokker-Plank equation is the Black-Scholes equation when F is interpreted as the price of an option and s as the price of the underlying stock.
