Description
The production of lepton pairs in two-photon UltraPeripheral Collision (UPC) draws significant interest for its characteristics of low extra hadronic activities. In particular, the $\gamma\gamma\rightarrow\tau\tau$ process provides a clean channel of tau lepton production. Such a property enables a precise measurement of tau anomalous magnetic moment $a_\tau$, providing a valuable probe of Beyond Standard Model Physics.
By carrying out a preliminary analysis of $\tau\tau$ decaying into the $e\nu_e\nu_\tau$, $\mu\nu_\mu\nu_\tau$ state, the potential to cleanly isolate the signal signature from background in LHCb's Run 2 dataset is investigated. Further research should establish the precision with which a measurement of the ultraperipheral di-tau production cross-section can be made, and therefore determine the feasibility of an $a_\tau$ measurement at the LHCb experiment.
