pp → ppπnear threshold in pionless effective theory

Regular Article - Theoretical Physics

Abstract.

The total cross-section of the ppppπ0 reaction near threshold is calculated in pionless effective field theory with a di-baryon and external pions. The amplitudes for a leading one-body and subleading contact neutral pion production vertex are obtained including the initial- and final-state interactions. After estimating a low-energy constant in the contact vertex, we compare our results for the total cross-section with the experimental data.
