Strategy to measure tau $g-2$ via photon fusion in LHC proton collisions

Lydia Beresford, Savannah Clawson, Jesse Liu

Measuring the tau-lepton ($\tau$) anomalous magnetic moment $a_{\tau }=(g_{\tau }-2)/2$ in photon fusion production ($\gamma \gamma \to \tau \tau$) tests foundational Standard Model principles. However, $\gamma \gamma \to \tau \tau$ e…
