Prospects for probing axionlike particles at a future hadron collider through top quark production

Abstract

Axionlike particles (ALPs) emerge from spontaneously broken global symmetries in high energy extensions of the Standard Model (SM). This causes ALPs to be among the objectives of future experiments which intend to search for new physics beyond the SM. We discuss the reach of future pp collider FCC-hh in probing the ALP model parameters through top quark pair production associated with ALP ($t\bar{t}+\text{ALP}$) in a model-independent approach. The search is performed in the semileptonic decay mode of $t\bar{t}$ and the analysis is performed using a parametric simulation of the detector response for a projected integrated luminosity of $30\mathrm{a}{\mathrm{b}}^{-1}$. It is shown that $t\bar{t}+\text{ALP}$ production at the FCC-hh is a promising channel with significant sensitivity to probe the ALP coupling with gluons. The ALP coupling with gluons obtained from HL-LHC and other experiments are presented for comparison.
