FCC-he sensitivity estimates on the anomalous electromagnetic dipole moments of the top-quark

Abstract

In this paper, we study the production of a top-quark in association with a bottom-quark and a electron-neutrino at the Future Circular Collider Hadron Electron (FCC-he) to probe the sensitivity on its magnetic moment (aˆV) and its electromagnetic dipole moment (aˆA) through the process e−p→e−γp→t¯νebp. Assuming a large amount of collisions, as well as of data with cleaner environments, the FCC-he is an excellent option to study new physics, such as the aˆV and aˆA. For our sensitivity study on aˆV and aˆA, we consider center-of-mass energies s=7.07,10 TeV and luminosities L=50,100,300,500,1000 fb−1. In addition, we apply systematic uncertainties δsys=0%,3%,5% and we consider unpolarized and polarized electron beam. Our results show that the FCC-he is a very good perspective to probe the aˆV and aˆA at high-energy and high-luminosity frontier.
