  In $p$-adic Hodge theory and the $p$-adic Langlands program, Banach spaces
with $\mathbb{Q}_p$-coefficients and $p$-adic Lie group actions are central.
Studying the subrepresentation of $\Gamma$-locally analytic vectors,
$W^{\mathrm{la}}$, is useful because $W^{\mathrm{la}}$ can be analyzed via the
Lie algebra $\mathrm{Lie}(\Gamma)$, which simplifies the action of $\Gamma$.
Additionally, $W^{\mathrm{la}}$ often behaves as a decompletion of $W$, making
it closer to an algebraic or geometric object.
  This article introduces a notion of locally analytic vectors for $W$ in a
mixed characteristic setting, specifically for $\mathbb{Z}_p$-Tate algebras.
This generalization encompasses the classical definition and also specializes
to super-H\"older vectors in characteristic $p$. Using binomial expansions
instead of Taylor series, this new definition bridges locally analytic vectors
in characteristic $0$ and $p$.
  Our main theorem shows that under certain conditions, the map $W \mapsto
W^{\mathrm{la}}$ acts as a descent, and the derived locally analytic vectors
$\mathrm{R}_{\mathrm{la}}^i(W)$ vanish for $i \geq 1$. This result extends
Theorem C of \cite{Po24}, providing new tools for propagating information about
locally analytic vectors from characteristic $0$ to characteristic $p$.
  We provide three applications: a new proof of Berger-Rozensztajn's main
result using characteristic $0$ methods, the introduction of an integral
multivariable ring $\widetilde{\mathbf{A}}_{\mathrm{LT}}^{\dagger,\mathrm{la}}$
in the Lubin-Tate setting, and a novel interpretation of the classical Cohen
ring ${\mathbf{A}}_{\mathbb{Q}_p}$ from the theory of
$(\varphi,\Gamma)$-modules in terms of locally analytic vectors.
