Photon-jet events as a probe of axion-like particles at the LHC

Abstract

Axion-like particles (ALPs) are predicted by many extensions of the Standard Model (SM). When ALP mass lies in the range of MeV to GeV, the cosmology and astrophysics will be largely irrelevant. In this work, we investigate such light ALPs through the ALP-strahlung process $pp\to Va(\to \gamma \gamma )$ at the 14 TeV LHC with an integrated luminosity of 3000 fb${}^{-1}$ (HL-LHC). With the photon-jet algorithm, we demonstrate that our approach can probe the mass range of ALPs, which is inaccessible to previous LHC experiments. The obtained result can surpass the existing limits on ALP-photon coupling in the ALP mass range from 0.3 GeV to 10 GeV.
