In this paper, we provide a new Bennequin-type inequality for the Rasmussen–Beliakova–Wehrli invariant, featuring the numerical transverse braid invariants (the -invariants) introduced by the author. From the Bennequin type-inequality and a combinatorial bound on the value of the -invariants we deduce a new computable bound on the Rasmussen invariant.
