Consider an $n$-dimensional convex set $K \subset \mathbb{R}^n$ and let $\mu$ denote the Gaussian measure with density
$$
\gamma(\mathbf{x}) = \frac{1}{(2\pi)^{n/2}} e^{-\lVert \mathbf{x} \rVert^2/2}.
$$
I am trying to figure out if, as I slide the convex body $K$ along a straight line, its Gaussian measure, viewed as a function of the line parameter, is a function that has a unique local and global maximum. In essence, I want to know if
$$
g \colon \ \mathbb{R} \to \mathbb{R}_+, \ t \mapsto \mu(\mathbf{u} + t\mathbf{v} + K)
$$
is log-concave or quasi-concave.
