Measurement of absorption and charge exchange of $\pi^+$ on carbon

Understand

The combined cross section for absorption and charge exchange interactions of positively charged pions with carbon nuclei for the momentum range 200 MeV/c to 300 MeV/c have been measured with the DUET experiment at TRIUMF.

• The uncertainty is reduced by nearly half compared to previous experiments.
• This result will be a valuable input to existing models to constrain pion interactions with nuclei.
