Bounds on the scale of noncommutativity from mono photon production in ATLAS Runs -1 and -2 experiments at LHC energies

Abstract: Leading order study of direct photon production from proton-proton collisions, in the framework of Minimal (Seiberg-Witten) Non-Commutative Standard Model (NCSM), taking into account the Earth-rotation effects. We found that relative non-commutative contributions increase significantly at very high photon transverse momentum. Therefore, using Run-1 (\sqrt{s}= 8 TeV) and Run-2 (\sqrt{s}= 13 TeV) ATLAS experimental data of inclusive isolated prompt photon cross-section, TeV-Scale bounds of the non-commutativity (NC) parameter are obtained. For space-space non-commutativity, we obtain: {\Lambda}b=1.145 \pm 0.015 TeV , and for space-time non-commutativity, we obtain : {\Lambda}e=1.125 \pm 0.035 TeV.
