We measured the in flight annihilation frequencies and cross sections of reactions nbar p --> pi+ pi0, pi+ eta, K+ KS, in the antineutron momentum range between 50 and 400 MeV/c. The annihilation frequencies of these channels from the different allowed initial states were calculated and some information about the nbar-p annihilation dynamics were obtained. The first determination of the D-wave contribution in this momentum range was also obtained.

Abstract
We measured the in flight annihilation frequencies and cross sections of reactions nbar p --> pi+ pi0, pi+ eta, K+ KS, in the antineutron momentum range between 50 and 400 MeV/c. The annihilation frequencies of these channels from the different allowed initial states were calculated and some information about the nbar-p annihilation dynamics were obtained. The first determination of the D-wave contribution in this momentum range was also obtained.File in questo prodotto:
