The anomalous magnetic moment of a lepton is sensitive to contributions from all three sectors of the Standard Model, as well as many beyond Standard Model theories. Due to the short decay time of the tau lepon, its anomalous magnetic moment can only be measured indirectly through its decay products. In this talk, we give a short introduction to tau anomalous magnetic moment, effective-field-theory (EFT) approach to the effective gamma-tau-tau vertex with dim-6 operators and matching conditions. We also explore detection strategies at colliders, with an emphasis on recent measurements and results from the LHC. Special attention will be given to the latest LHC findings. The strengths and limitations of EFT-based methods will be outlined, along with a discussion of different experimental approaches, including studies in both proton-proton and heavy-ion collisions.

Natascia Vignaroli is currently a temporary researcher (RTD-A) in the physics department of the “Università del Salento”. She is also associated with INFN and Short-Term-Associated with the ATLAS collaboration. Vignaroli received her PhD from the University of Rome "La Sapienza" in 2012 and has over ten years of research experience in several international institutions: University of Naples (Italy), University of Pisa (Italy), INFN Padua (Italy), CP3-Origins (Denmark), Michigan State University (USA), Iowa State University (USA). Her research activity is focused on the phenomenology of theories beyond the Standard Model (BSM), with emphasis on the search for new physics at colliders (LHC and future colliders).

Arash Jofrehei is a CMS member since 2015. Received the BSc and MSc from Sharif University of Technology. Did the PhD at University of Zurich (UZH), leading two measurements of anomalous magnetic moment of tau from CMS and working on the upgrade of the CMS tracker for HL-LHC. Now is currently a postdoc at UZH.
