Abstract

A measurement of the spectral functions of non-strange τ vector current final states is presented, using 124 358 τ pairs recorded by the ALEPH detector at LEP during the years 1991 to 1994. The spectral functions of the dominant two- and four-pion τ decay channels are compared to published results of e⁺e^- annihilation experiments via isospin rotation. A combined fit of the pion form factor from τ decays and e⁺e^- data is performed using different parametrizations. The mass and the width of the ρ^±(770) and the ρ⁰(770) are separately determined in order to extract possible isospin violating effects. The mass and width differences are measured to be M_ρ±(770) - M_ρ0(770) = (0.0 ± 1.0) MeV/c² and Γ_ρ±(770) - Γ_ρ0(770) = (0.1 ± 1.9) MeV/c².

N2 - A measurement of the spectral functions of non-strange τ vector current final states is presented, using 124 358 τ pairs recorded by the ALEPH detector at LEP during the years 1991 to 1994. The spectral functions of the dominant two- and four-pion τ decay channels are compared to published results of e+e- annihilation experiments via isospin rotation. A combined fit of the pion form factor from τ decays and e+e- data is performed using different parametrizations. The mass and the width of the ρ±(770) and the ρ0(770) are separately determined in order to extract possible isospin violating effects. The mass and width differences are measured to be Mρ±(770) - Mρ0(770) = (0.0 ± 1.0) MeV/c2 and Γρ±(770) - Γρ0(770) = (0.1 ± 1.9) MeV/c2.
