Experimental Tests of Lepton Universality in Tau Decay from CLEO
The branching fractions for !ee, , and hh are measured using data collected with the, where the rst errors are statistical, the second systematic, and h refers either to a charged or K. Also measured is the tau mass, m=(1778.21.4) MeV. Lepton universality is aarmed by the resulting relative branching fractions (B/Be=0.97770.00630.0087, B h /Be=0.64840.00410.0060) and the charged-current gauge c...
متن کاملObservation of Upsilon(3S)-->tau+tau- and tests of lepton universality in Upsilon decays.
Using data collected with the CLEO III detector at the CESR e+e- collider, we report on a first observation of the decay Upsilon(3S)-->tau+tau-, and precisely measure the ratio of branching fractions of Upsilon(nS), n=1, 2, 3, to tau+tau- and mu+mu- final states, finding agreement with expectations from lepton universality. We derive absolute branching fractions for these decays, and also set a...
متن کاملLepton Universality Tests with Kaons
Precision data on K l3 and K l2 decay rates and form factors allow us to perform significant tests of lepton universality and to constrain the strength of non-standard interactions. The present status of these tests and new physics searches are discussed, as obtained by combining all the available results of the various kaon physics experiments. c Copyright owned by the author(s) under the term...
متن کاملNew Results from Cleo-ii on Hadronic Decays of the Tau Lepton
Results on semi-hadronic decays of the τ lepton are presented, from studies of e+e− annihilation data obtained at the Cornell Electron Storage Ring with the CLEO-II detector. Branching fractions have been measured for decays to two, three and four hadrons, namely τ→ ντhπ, τ→ ντhhh, and τ→ντhhhπ, where h represents a charged pion or kaon. CLEO-II has also observed decays with charged and/or neut...
متن کاملSoftware for physics of tau lepton decay in LHC experiments
Software development in high energy physics experiments offers unique experience with rapidly changing environment and variety of different standards and frameworks that software must be adapted to. As such, regular methods of software development are hard to use as they do not take into account how greatly some of these changes influence the whole structure. The following thesis summarizes dev...
