Rationality of Brauer-Severi surface bundles over rational 3-folds
We give a sufficient condition for a Brauer-Severi surface bundle over a
rational 3-fold to not be stably rational. Additionally, we present an example
that satisfies this condition and demonstrate the existence of families of
Brauer-Severi surface bundles whose general members are smooth and not stably
rational.
