Abstract

The preliminary results obtained by the GRAAL collaboration for the π⁰π⁺ photoproduction on the free and quasi-free proton (deuteron) at E_γ = 0.7-1.5 GeV are presented. The total cross section of the γp → π⁰π⁺n reaction and invariant mass spectra for the π⁺π⁰, π⁺n and π⁰n systems are presented in the photon energy range from 0.7 to 1.5 GeV. These results are in good agreement with the 2π-MAID calculations.

World Scientific Publishing Company was established in 1981 with only 5 employees in a tiny office. Today, the company employs more than 200 staff at its headquarters in Singapore and 450 globally. It has offices in New Jersey, London, Geneva, Hong Kong, Taipei, Beijing, Shanghai, Tianjin and Chennai. In about 3 decades, it has established itself as one of the leading scientific publishers in the world, and the largest international scientific publisher in the Asia-Pacific region. World Scientific publishes about 600 new titles a year and 130 journals in various fields.

The International Journal of Modern Physics E covers the topics on experimental, theoretical and computational nuclear science, and its applications and interface with astrophysics and particle physics. The journal includes both review articles and research papers.
