Complete next-to-leading order calculation for pion production in nucleon nucleon collisions at threshold
Complete next-to-leading order calculation for pion production in nucleon nucleon collisions at threshold
Based on a counting scheme that explicitly takes into account the large momentum Mm(pi) characteristic for pion production in nucleon-nucleon collisions we calculate all diagrams for the reaction NN-->NNpi at threshold up to next-to-leading-order. At this order there are no free parameters and th...

Based on a counting scheme that explicitly takes into account the large momentum Mm(pi) characteristic for pion production in nucleon-nucleon collisions we calculate all diagrams for the reaction NN-->NNpi at threshold up to next-to-leading-order. At this order there are no free parameters and the size of the next-to-leading- order contributions is in line with the expectation from power counting. The sum of loop corrections at that order vanishes for the process pp-->pppi(0) at threshold. The total contribution at next-to-leading-order from loop diagrams that include the delta degree of freedom vanishes at threshold in both reaction channels pp-->pppi(0),pnpi(+). |
