Abstract
An -space knot is a knot that admits a positive Dehn surgery yielding an -space. Many known hyperbolic -space knots are braid positive, meaning they can be represented as the closure of a positive braid. Recently, Baker and Kegel showed that the hyperbolic -space knot from Dunfield's census is not braid positive, and they constructed infinitely many candidates for hyperbolic -space knots that may not be braid positive. However, it remains unproven whether their examples are genuinely non-braid positive. In this paper, we construct infinitely many hyperbolic -space knots that are not braid positive, and our examples are distinct from those considered by Baker and Kegel.
