Narrow resonances at the early LHC

We discuss the possibility to observe new resonances at the early LHC using a phenomenological approach. We show predictions for the production of a scalar in the gg-channel and an heavy quark in the qg-channel and we compare them with the recent results of the ATLAS and CMS experiments in the di-jet channel, setting upper limits on the relevant couplings. We finally discuss the importance of the final states containing at least one photon making sensitivity predictions for the corresponding couplings.
