Measurement of $\sigma_{\mathrm{ABS}}$ and $\sigma_{\mathrm{CX}}$ of $\pi^+$ on carbon by DUET

The DUET Collaboration reports on the measurements of the absorption ($sigma_{mathrm{ABS}}$) and charge exchange ($sigma_{mathrm{CX}}$) cross sections of positively charged pions on carbon nuclei for the momentum range 201.6 MeV$/c$ to 295.1 MeV$/c$. The uncertainties on the absorption and charge exchange cross sections are $sim$9.5% and $sim$18%, respectively. The results are in good agreement with previous experiments. A covariance matrix correlating the 5 $sigma_{mathrm{ABS}}$ and 5 $sigma_{mathrm{CX}}$ measured data points is also reported
