Search for Antineutrino Charged Current Coherent Pion Production at SciBooNE

Understand

The SciBooNE experiment (Fermilab) recently published results of a search for charged current coherent pion production in neutrino mode: muon neutrinos scattering on carbon.

• The results of this study are that no evidence for coherent pion production is observed, and SciBooNE set 90% confidence level upper limits on the cross section ratio of charged current coherent pion production to the total charged current cross section.
• Recently proposed new coherent pion models predict a production of charged current coherent pion events just below the SciBooNE's upper limit.
• Motivated by this, we performed a search for charged current coherent pion production using SciBooNE's collected antineutrino data since antineutrino data are expected to be more sensitive to look at coherent pion production than neutrino data.
