| Abstract: The paper presents a search for excited quarks $(q^{\star})$ decaying into a $\gamma+\mathrm{jet}$ final state at $\sqrt{s} = $ 8 TeV with the CMS experiment, using the dataset corresponding to an integrated luminosity of 19.7 fb$^{-1}$ collected during 2012 data taking at the LHC. Photons and $\mathrm{jets}$ with high transverse momentum are selected to search for a resonance peak in the $\gamma+\mathrm{jet}$ invariant mass distribution. The 95% confidence level upper limits on cross section times branching ratio are evaluated as a function of excited quark mass ($M_{\mathrm q^{\star}}$). We exclude at 95% CL excited quarks with 0.7 $< M_{\mathrm q^{\star}} <$ 3.5 TeV for standard model couplings, and present exclusions of excited quark mass as a function of coupling strength. | ||
