نویسنده
چکیده
I present two analyses done with the CLEOIII detector at CESR. The first is a search for the LFV decay Υ → µτ with preliminary results, and the second constrains Lepton Universality in Υ → τ τ relative to Υ → µµ. This second analysis, whose results are final, has dramatically improved uncertainties relative to other such measurements, and is also the first observation of the decay Υ(3S) → τ τ. A limit is also set on the involvement of a CP odd Higgs in the decay of the Υ(1S) to τ pairs.

Simple “unitarity inspired” relations between twoand three-body lepton flavor violating decays are noted and discussed. In the absence of cancellations, the existing strong bounds on μ→ 3e and μ→ eγγ severly constrain two-body lepton flavor violating decays. Lepton flavor violating (LFV) processes are strongly suppressed in the standard model by powers of (small) neutrino masses. Such decays si...

The main physics goals of a high luminosity ee flavor factory are discussed, including the possibilities to perform detailed studies of the CKM mechanism of quark mixing, and constrain virtual Higgs and non-standard model particle contributions to the dynamics of rare Bu,d,s decays. The large samples of D mesons and τ leptons produced at a flavor factory will result in improved sensitivities on...

We present an update of previous work on charged lepton flavor violation (LFV) in the seesaw model. The most recent neutrino data fits and post WMAP mSUGRA benchmark scenarios are used as input. In this framework we compare the sensitivity of rare radiative decays on the right-handed Ma-jorana mass scale M R with the reach in slepton-pair production at a future linear collider.

In spring 2003, the B physics era ended for the CLEO experiment with a final run at the Υ(5S) resonance. Over the summer the experiment and the CESR accelerator were modified to operate at lower center-of-mass energies between 3 and 5 GeV. In September 2003 the CLEO-c detector has begun to take its first data at the ψ(3770) resonance, with which a new era for the exploration of the charmonium s...
