$$\frac{dx(t)}{dt}=b(t,x(t))$$
which can have existence but not uniqueness eg. for $b(x):=2sgn(x)\sqrt{|x|}$, whereas …

Reference: hitting time of Gaussian process
Since they are independent, lets start with treating $W_{t}$ as a deterministic Holder-continuous function (and so lets interpret it as the t-dependent mean of the first term).
Indeed, in "Hitting tim …
