Fermilab charged lepton program • CLFV new mixing matrix • Multi-decade program to determine 4 free parameters • Flavor conserving • Muon g-2 • Flavor violating • Mu2e • Next generation Mu2e @ Project X • meg, meee , m+e-e+m- also being considered @ Project X • CP violating • e EDM with rare isotopes • m EDM storage ring experiments B. Casey, BNL Colloquium
Around the world Physics for the next 4 decades: Cold traps, intense muon sources, super B factories, t/charm factories, lepton colliders, Hadron colliders… m→eg, mN→eN t→eg, eee t→mg, mmm (g-2)e, (g-2)m, (g-2)t CP violation: lepton EDM measurements B. Casey, BNL Colloquium
Kick starting the program:the new muon g-2 experiment Pbar complex target ring B. Casey, BNL Colloquium • Follow up of BNL experiment but better: • Reuse the storage ring • 10x longer decay channel • Segmented calorimeters • Tracking • >20x statistics, >2x less systematics • Coupled with a world wide program to interpret the measurement

It’s happening! • Hadronic Light by Light scattering is the last major component of predicted value based on model dependent calculations • New program at KLOE to measure dominant contributions to this diagram with 2 photon physics at very low Q2 • With this new data, (g-2)m theory error will be almost entirely driven by independent experiments B. Casey, BNL Colloquium

Conclusions “It ain’t over till its over.” -Yogi Berra ‘Fermilab program’ builds in many ways on Brookhaven ideas and accomplishments Fermilab is the right place at the right time Brookhaven is a strong collaborator on many of these projects and is essential to the success of the program B.
