J/psi的轻介子离解和手征对称性

The dissociation of the J/psi by light mesons and chiral symmetry

Alex Bourque, Charles Gale

摘要:

手征对称性的π介子诱导的J/psi的解离的影响进行了详细的研究。它示出了如何低能动力学的π介子,受手征对称性,影响的解离截面。导出的软π介子定理,然后集成到一个拉格朗日模型,其中还包括异常宇称内容和手征对称形状因子。也被认为是由ρ介子离解。

英文摘要:

The implication of chiral symmetry for the pion-induced dissociation of the J/psi is examined in detail. It is shown how the low-energy dynamics of pions, constrained by chiral symmetry, affect the dissociation cross-section. The derived soft-pion theorem is then integrated into a Lagrangian model which includes also abnormal parity content and chiral-symmetric form factors. Dissociation by the rho meson is also considered.
