Abstract

We have searched for the lepton-flavor-violating decays τ- decays into ℓ-KS 0 and ℓ-KS 0KS 0 (ℓ=e or μ), using a data sample of 671 fb-1 collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. No evidence for a signal was found in any of the decay modes, and we set the following upper limits for the branching fractions: B(τ-→e-KS 0)

Lepton

In particle physics, a lepton is an elementary particle of half-integer spin (spin ) that does not undergo strong interactions. Two main classes of leptons exist: charged leptons (also known as the electron-like leptons or muons), and neutral leptons (better known as neutrinos). Charged leptons can combine with other particles to form various composite particles such as atoms and positronium, while neutrinos rarely interact with anything, and are consequently rarely observed. The best known of all leptons is the electron.

Greek alphabet

The Greek alphabet has been used to write the Greek language since the late 9th or early 8th century BC. It is derived from the earlier Phoenician alphabet, and was the earliest known alphabetic script to have distinct letters for vowels as well as consonants. In Archaic and early Classical times, the Greek alphabet existed in many local variants, but, by the end of the 4th century BC, the Euclidean alphabet, with 24 letters, ordered from alpha to omega, had become standard and it is this version that is still used for Greek writing today.

Sampi

Sampi (modern: ϡ; ancient shapes: , ) is an archaic letter of the Greek alphabet. It was used as an addition to the classical 24-letter alphabet in some eastern Ionic dialects of ancient Greek in the 6th and 5th centuries BC, to denote some type of a sibilant sound, probably [ss] or [ts], and was abandoned when the sound disappeared from Greek. It later remained in use as a numeral symbol for 900 in the alphabetic ("Milesian") system of Greek numerals.
