11. Monte Carlos for tau lepton Standard Model and New Physics signatures

Zbigniew Andrzej Was (Polish Academy of Sciences)

04/12/2023, 10:25

Plenary Presentation

The measurements of heaviest leptons tau, offer window for precision tests of Standard Model electroweak and medium energy strong interactions. They also are expected to be useful for New Physics signatures. The short lived tau leptons are observed through their decay products. The tau neutrinos escape detection.That complicates phenomenological work, but at the same time enables access to the...

51. Flavor-changing neutral currents in tau decays

Alexey Petrov (University of South Carolina)

Plenary Presentation

We discuss constraints on the flavor-changing neutral current transitions of taus with photons and gluons.

19. Charged Lepton Flavor Violation in Heavy Particle Decays

Wolfgang Altmannshofer (UC Santa Cruz)

04/12/2023, 11:15

Plenary Presentation

Lepton flavor violation (LFV) is one of the cleanest probes of physics beyond the standard model. I will summarize the theoretical and experimental status of the search for charged lepton flavor violation in heavy particle decays, in particular in the decays of the Z and Higgs bosons, and of the top quark. Decays of beyond-Standard-Model particles such as a Z' or an additional scalar particle...

26. Charged lepton flavor violation at circular e+e- colliders

Pankaj Munbodh (University of California Santa Cruz)

04/12/2023, 11:40

Plenary Presentation

Lepton flavor violation is one of the cleanest probes of physics beyond the standard model. In this work, we explore the sensitivity of the process $e^+e^-\to\tau\mu$ to new physics above the TeV scale at the proposed circular electron-positron colliders FCC-ee and CEPC. We compute the $e^+e^-\to\tau\mu$ cross-section in the Standard Model Effective Field Theory and assess the relevant...

90. What if cLFV was only detectable in tau decays?

Dr Innes Bigaran (Fermilab and Northwestern University)

04/12/2023, 12:05

Plenary Presentation

The observation of massive neutrino oscillations indicate that lepton flavour is violated beyond the renormalizable standard model (SM). However, extending the SM by merely the existence of neutrino oscillations does not predict an observably large signal in charged lepton flavour violating (cLFV) searches. Therefore, a detection of cLFV would represent a genuine signal of new physics effects...
