• # Abstract

The measurement of the inclusive cross-section for $Z\gamma$ production at LHC with 7 TeV proton–proton collision is presented. The electron and muon decay modes are used to reconstruct the 𝑍 boson. The total cross-section is measured for photon transverse energy greater than 10 GeV and with photon and charged lepton separation in the pseudorapidity-azimuthal angle plane greater than 0.7. This study is extended by a measurement of $Z(\nu \bar{\nu})\gamma$ cross-section. A search is performed for extra dimensions in the Arkani-Hamed, Dimopoulos, Dvali framework using the final state of a graviton and photon. The limits are extended with MD $&gt; 1.25–1.31$ TeV for $n = 2-6$. The measurement is found to be in agreement with the Standard Model prediction.
