Higgs To Four Taus At ALEPH

A search has been performed on $683 pb^{−1}$ of data collected by the ALEPH detector at the Large Electron-Positron (LEP), collider at centre-of-mass energies from 183 to 209 GeV looking for a Higgs boson decaying into four τ leptons via intermediate pseudoscalar a particles, for a Higgs mass range...

description A search has been performed on $683 pb^{−1}$ of data collected by the ALEPH detector at the Large Electron-Positron (LEP), collider at centre-of-mass energies from 183 to 209 GeV looking for a Higgs boson decaying into four τ leptons via intermediate pseudoscalar a particles, for a Higgs mass range of 70 to $114 GeV/c^2$ and an a mass range of 4 to $12 GeV/c^2$. No excess above background is seen and a limit is placed on $ξ^2 = \frac{σ(e^+ e^− \to Z+h)}{σ_{SM} (e^+ e^− \to Z+h)}$ × $(h \to \alpha \alpha) × (\alpha \to τ^+ τ^−)^2$ in the $m_h , m_a$ plane. For $m_h < 107 GeV/c^2$ and $m_a < 10 GeV/c^2 , ξ^2$ > 1 can be excluded at the 95% confidence level.
