abstract = {{To date, no dedicated attempt has been made to correct skew-sextupole resonances in the LHC at injection. Recently this topic has gained interest however, following the investigation for the emittance growth generation during the LHC energy ramp, due to third order islands. The LHC is equipped with skew-sextupole correctors in the experimental insertions (MCSSX), intended for local compensation at top energy, and with several families of skew sextupole magnets in the arcs (MSS), which are intended for chromatic coupling compensation at top energy but are not optimally placed for resonance compensation. Simulation studies were performed in MAD-X and PTC to assess whether the MSS and MCSSX correctors could be used to compensate skew-sextupole RDTs in the LHC at injection via a response matrix approach, based on measured values at the LHC BPMs. It was found that compensation was viable, but at the cost of significantly increased corrector strength compared to chromatic coupling compensation.}},
