The pi N -> pi pi N reaction around the N(1440) energy
Hiroyuki Kamano, Masaki Arima
We study the pi N -> pi pi N reaction around the N(1440) mass-shell energy. Considering the total cross sections and invariant mass distributions, we discuss the role of N(1440) an…

Chiral Symmetry and N*(1440) -> N pi pi Decay
H. Kamano, M. Morishita, M. Arima
The N*(1440) -> N pi pi decay is studied by making use of the chiral reduction formula. This formula suggests a scalar-isoscalar pion-baryon contact interaction which is absent in…
