TL;DR
This paper reports precise measurements of how positively charged pions are absorbed or undergo charge exchange when interacting with carbon nuclei, providing crucial data to improve nuclear interaction models.
Contribution
It presents the first high-precision measurement of the combined absorption and charge exchange cross section of $^+$ on carbon in the 200-300 MeV/c range, reducing uncertainties significantly.
Findings
Uncertainty reduced by nearly 50% compared to previous data.
Provides valuable input for constraining pion-nucleus interaction models.
Enhances understanding of pion interactions at relevant energies.
Abstract
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.
