We analyze Khovanov homology of twist deformations of torus links and show that counterexamples to the PS braid conjecture can be obtained in this procedure. Moreover, we provide some examples showing that the Khovanov homology of the flat 2-cabling of a given knot may contain interesting torsion subgroups.
