  1. Searching for Lepton Flavor Violation at LHCb Matt Jaffe Physics Department, Penn State University

  2. The LHCb Experiment • Indirect search for new physics • Matter/antimatter asymmetry • Measurement of rare decays • Lepton Flavor Violating Decays • 700 scientists from • 52 institutions Matt Jaffe Penn State University

  3. Lepton Flavor Violation (?) Electron #: +1 0 0 0 Muon #: +1 0 +1 Tau #: 0 0 And negative for corresponding anti particles Matt Jaffe Penn State University

  4. τ -> μμμ Decay • Standard Model Branching Ratio: ~10-54 • Branching ratio in some New Physics models: 10-8 - 10-10 ! • SM + Heavy Majoranaνr • SUSY SO(10) • mSUGRA + seesaw OR (more likely) Matt Jaffe Penn State University

  5. Selection Cuts Goals • Eliminate all background events • Maximize τ -> μμμ efficiency • Select appropriate control channels x 200 How • Throw out a huge majority of the data • - intelligently! Matt Jaffe Penn State University

  6. Swiss Ultimate Nationals! Cham Matt Jaffe Penn State University
