DESCRIPTION:AbstractA direct discovery of lepton flavor violation (LFV) at
  colliders would be a smoking gun for new physics\, since such processes a
 re highly suppressed in the Standard Model. In this talk\, LFV transitions
  in tau decays will be discussed\, with a particular focus on τ→μ chan
 nels. The first part will introduce the theoretical framework\, including 
 the main phenomenological motivations and representative new physics scena
 rios that can lead to observable effects. The second part will present the
  recent results from the LHCb experiment on the search for the decay τ→
 μμμ\, focusing on the determination of the upper limit on its branching
  fraction using Run 2 data\, and discussing the prospects for improved sen
 sitivity in Run 3.\nSpeakers\nGiulia Frau \nI completed my undergraduate 
 studies at the University of Cagliari and obtained my PhD from Heidelberg 
 University in summer 2023\, with a thesis titled “Search for the tau->mu
 mumu decay at the LHCb experiment”. Since March 2024\, I have been a pos
 tdoctoral research associate in the LHCb group of the University of Manche
 ster\, fully based at CERN. Since 2026\, I have served as convener of the 
 Very Rare Decays sub-working group. Besides very rare decay analyses\, I a
 lso work on the ASLD analysis\, focusing on CP violation measurements in B
 0-B0bar mixing. Finally\, I coordinate alignment and online calibration ac
 tivities for the 2026 data-taking. \n \nMarco Ardu \nMy research focuse
 s on beyond the Standard Model phenomenology\, with a particular interest 
 in low-energy precision observables. I completed my undergraduate studies 
 at the University of Pisa and obtained my PhD in Montpellier under the sup
 ervision of Sacha Davidson\, with a thesis on effective field theories and
  lepton flavour violation. I am currently finishing my first postdoctoral 
 position at the Instituto de Fisica Corpuscular (IFIC) in Valencia\, and I
  will soon begin my second postdoc at the Instituto Nazionale di Fisica Nu
 cleare (INFN) in Padova.\n\nhttps://indico.cern.ch/event/1683460/
