Abstract
The probability of large-angle scattering for multi-GeV muons in thin ($t/X_0 \sim 10^{-1}$) lead targets is studied. The new estimates presented here are based both on simulation programs (GEANT4 libraries) and theoretical calculations. In order to validate the results provided by simulation, a comparison is drawn with experimental data from the literature. This study is particularly relevant when applied to muons originating from $ν_μ^{CC}$ interactions of CNGS beam neutrinos. In that circumstance the process under study represents the main background for the $ν_μ\to ν_τ$ search in the $τ\to μ$ channel for the OPERA experiment at LNGS. Finally, we also investigate, in the CNGS context, possible contributions from the muon photo-nuclear process which might in principle also produce a large-angle muon scattering signature in the detector.
Methology: I did a search of http://arxiv.org/find/hep-ex/1/abs:+codes/0/1/0/all/0/1?quer... for "codes" in hep-ex entries at arXiv.org and reported the first few papers which actually contained "codes". (It appears that stemming is in place, as some papers only had 'code'.)…
