A study of strange particle production in nu(mu) charged current interactions in the NOMAD experiment

subject

description

A study of strange particle production in $\nu_\mu$ charged current interactions has been performed using the data from the NOMAD experiment. Yields of neutral strange particles ($K^0_s, \Lambda, \bar{\Lambda}$) have been measured. Mean multiplicities are reported as a function of the event kinematic variables $E_\nu$, $W^2$ and $Q^2$ as well as of the variables describing particle behaviour within a hadronic jet: $x_F$, $z$ and $p_T^2$. Decays of resonances and heavy hyperons with identified $K^0_s$ and $\Lambda$ in the final state have been analyzed. Clear signals corresponding to $\rm {K^\star}^\pm$ $\rm {\Sigma^\star}^\pm$, $\rm \Xi^-$ and $\rm \Sigma^0$ have been observed. A study of strange particle production in ν μ charged current interactions has been performed using the data from the NOMAD experiment. Yields of neutral strange particles ( K 0 s ,Λ, Λ ̄ ) have been measured. Mean multiplicities are reported as a function of the event kinematic variables E ν , W 2 and Q 2 as well as of the variables describing particle behaviour within a hadronic jet: x F , z and p T 2 . Decays of resonances and heavy hyperons with identified K 0 s and Λ in the final state have been analyzed. Clear signals corresponding to K ★± , Σ ★± , Ξ − and Σ 0 have been observed. A study of strange particle production in muon neutrino charged current interactions has been performed using the data from the NOMAD experiment. Yields of neutral strange particles K0s, Lambda, AntiLambda have been measured. Mean multiplicities are reported as a function of the event kinematic variables Enu, W2 and Q2 as well as of the variables describing particle behaviour within a hadronic jet: xF, z and pT2. Decays of resonances and heavy hyperons with identified K0s and Lambda in the final state have been analyzed. Clear signals corresponding to K*+-, Sigma*+-, Xi- and Sigma0 have been observed.
