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

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 a...

Zusammenfassung: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
