, Physics Letters Section B Nuclear Elementary Particle and High Energy Physics, Vol: 418, Pages: 430-442, ISSN: 0370-2693The value of the b quark mass at the M<inf>2</inf> scale defined in the MS renormalization scheme, m<inf>b</inf>(M<inf>Z</inf>), was determined using 2.8 million hadronic Z decays collected during 1992-1994 by the DELPHI detector to be m<inf>b</inf>(M<inf>Z</inf>) = 2.67 ± 0.25 (stat.) ± 0.34 (frag.) ± 0.27 (theo.) GeV/c<sup>2</sup>. The analysis considers NLO corrections to the three-jet production rate including mass effects, and the result obtained agrees with the QCD prediction of having a running b quark mass at an energy scale equal to M<inf>Z</inf>. This is the first time that such a measurement is performed far above the bb̄ production threshold. The study also verifies the flavour independence of the strong coupling constant for b and light quarks within 1% accuracy. © 1998 Elsevier Science B.V.

K0 S production in τ decays
, European Physical Journal C, Vol: 4, Pages: 29-45, ISSN: 1434-6044From a sample of about 160k Z → τ<sup>+</sup>τ<sup>-</sup> candidates collected with the ALEPH detector at LEP between 1991 and 1995, τ lepton decays involving K<sup>0</sup> <inf>S</inf> → π<sup>+</sup>π<sup>-</sup> are studied. The K<sup>0</sup> <inf>S</inf>K<sup>0</sup> <inf>L</inf> associated production in τ decays is also investigated. The branching ratios are measured for the inclusive decay B(τ<sup>-</sup>→K<sup>0</sup> <inf>S</inf>X<sup>-</sup>ν <inf>τ</inf>) = (9.70±0.58±0.62) × 10<sup>-3</sup>, where X<sup>-</sup> can be anything, and for the exclusive decays B(τ<sup>-</sup>→K̄<sup>0</sup>π<sup>-</sup>ν <inf>τ</inf>) = (8.55±1.17±0.66) × 10<sup>-3</sup>, B(τ<sup>-</sup>→K̄<sup>0</sup>π<sup>-</sup>π <sup>0</sup>ν<inf>τ</inf>) = (2.94±0.73±0.37) × 10<sup>-3</sup>, B(τ<sup>-</sup>→K̄<sup>0</sup>K<sup>-</sup>ν<inf>τ</inf>) = (1.58±0.42±0.17) × 10<sup>-3</sup>, B(τ<sup>-</sup>→K̄<sup>0</sup>K<sup>-</sup>π <sup>0</sup>ν<inf>τ</inf>) = (1.52±0.76±0.21) × 10<sup>-3</sup>.

π±, K±, p and p̄ production in Z0 → qq̄, Z0 bb̄, Z0 → uū, dd̄, ss̄
, European Physical Journal C, Vol: 5, Pages: 585-620, ISSN: 1434-6044The DELPHI experiment at LEP uses Ring Imaging Cherenkov detectors for particle identification. The good understanding of the RICH detectors allows the identification of charged pions, kaons and protons, covering the full momentum range from 0.7 < p < 45.6GeV/c. The π<sup>±</sup>, K<sup>±</sup>, p and p̄ normalised production rates, their differential cross sections, multiplicities and the maxima ξ*<inf>p</inf> of_the ξ<inf>p</inf> = ln (1/X<inf>p</inf>) distributions are measured for three event samples Z<sup>0</sup> → qq̄, Z<sup>0</sup> → bb̄, Z<sup>0</sup> → uū, dd̄, ss̄, selected from ∼ 1 400 000 Z<inf>0</inf> decays collected by DELPHI in 1994. The results are compared to the predictions of the JETSET string fragmentation model and the HERWIG cluster fragmentation model. The Modified Leading Logarithm Approximation with Local Parton-Hadron Duality is tested. The ξ*<inf>p</inf> dependence on the primary quark flavour is investigated and quantified for the different particle distributions. The π<sup>±</sup> , K<sup>±</sup>, p and p̄ multiplicities are measured with precisions from ±4% to ±6%. Forche Z<sup>0</sup> → qq̄, and Z<sup>0</sup> → bb̄, event samples, these improve on previous measurements. The π<sup>±</sup>, K<sup>±</sup>, p and p̄ multiplicities for Z<sup>0</sup> → uū, dd̄, ss̄ are presented for the first time.
