Predictions based on the chirally normalized vector meson dominance model for decay rates and distributions of τ decays into Kππντ final states are discussed. Disagreements with experimental results can be traced back to the K1 widths. Hadronic τ decays into final states with kaons can provide detailed information about low energy hadron physics in the strange sector. Predictions for final stat...
متن کاملAspects of τ → Kh ( h ) ν τ Decays and Experimental Comparisons
Predictions for decay rates and distributions for τ decays into final states with kaons are discussed and compared with recent measurements. Special emphasis is put on new constraints for the vector current contribution in the KKπ decay modes. For the Kππ modes, disagreements with the experimental results can be traced back to the K1 widths.
متن کاملMeasurement of Branching Fractions in τ Decays
Full LEP-I data collected by the ALEPH detector during 1991-1995 running are analyzed in order to measure the τ decay branching fractions. The analysis follows the global method used in the published study based on 1991-1993 data, with several improvements, especially concerning the treatment of photons and π’s. Extensive systematic studies are performed, in order to match the large statistics ...
متن کاملProduction and Decay of Scalar Stoponium Bound States
In this paper we discuss possible signatures for the production of scalar t̃1t̃ ∗ 1 (stoponium) bound states σt̃1 at hadron colliders, where t̃1 is the lighter scalar top eigenstate. We first study the decay of σt̃1 ; explicit expressions are given for all potentially important decay modes. If t̃1 has unsuppressed two–body decays, they will always overwhelm the annihilation decays of σt̃1 . Among the ...
متن کاملRecent CLEO Results on Tau Hadronic Decays
When the τ lepton decays to 3 charged hadrons and a neutrino, the predominant decay mode involves three charged pions. Occasionally this decay will include one, two or three kaons in the final state. Each of these modes is useful for understanding different physics topics. The decay τ → Kππν is important in extracting the strange spectral function as well the strange quark mass and the CKM matr...
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...
