Integral topological Hochschild homology of connective complex K-theory

We compute the homotopy groups of $\mathrm{THH}(\mathrm{ku})$ as a $\mathrm{ku}_\ast$-module using the descent spectral sequence for the map $\mathrm{THH}(\mathrm{ku})\to\mathrm{THH}(\mathrm{ku}/\mathrm{MU})$, which is the motivic spectral sequence for $\mathrm{THH}(\mathrm{ku})$ in the sense of Hahn-Raksit-Wilson. We compute the $E_2$-page using an algebraic Bockstein spectral sequence, which is an approximation to the topological Bockstein spectral sequence computing $\mathrm{THH}(\mathrm{ku})$ from $\mathrm{THH}(\mathrm{ku})/(p,\beta)$, where $\beta$ is the Bott element. Then, we show that the descent spectral sequence degenerates at the $E_2$-page.Comment: Minor edits, comments welcome, 20 pages, 1 figur
