Scalar Leptoquark Contribution to Two Photon Elastic Scattering (2405.16210v2)
Published 25 May 2024 in hep-ph
Abstract: We study the contribution of Scalar Leptoquark (SLQ) loops to the two photon scattering cross section at high energies. The leading order helicity amplitudes are discussed at coupling O(e4) for Standard Model (SM) fermions, weak bosons and SLQs. Helicity amplitudes for the different types of loops are calculated for photon center of mass energies being much higher than weak boson mass scale but still much lower than the predicted Leptoquark mass scales. Finally, the cross section due to the SLQ loops is presented in conjunction with the known SM contribution.
