Title :  Seifert fibered surgeries on hyperbolic fibered knots

AbstractLet K be a hyperbolic fibered knot such that p/q-surgery on K is either reducible or an atoroidal Seifert fibered space. We prove that if the monodromy of K is right-veering, then 0≤ p/q ≤ 4g(K). The upper bound 4g(K) cannot be attained if K is an L-space knot. As a consequence, we get new results on the characterizing slopes of torus knots.
