Right-handed light quarks can be significantly composite and still be compatible with experimental searches at the LHC and precision tests on Standard Model couplings. In these scenarios, which are also motivated by flavor physics, one expects large cross sections for the production of new resonances coupled to the light quarks. We study possible experimental strong signatures of right- handed compositeness at the LHC and constrain the parameter space of these scenarios with recent results by ATLAS and CMS. We show that the LHC sensitivity could be significantly improved if dedicated searches were performed in particular in multi jet signals.
