场论模型中奇异度-1和奇异度-2超核的产生

Production of strangeness -1 and -2 hypernuclei within a field theoretic model

R. Shyam

摘要:

我们提出了一个全面的协变配方描述生产的奇异性-1和-2超核使用不同种类的探针的概述。该理论基于一个有效的拉格朗日图像,它侧重于通过创建,传播和衰变到相关通道的中间重子共振态在初始碰撞的弹丸与一个目标核子的产生振幅。用适当的标量势和矢量势求解狄拉克方程,得到了束缚态核子和超子的波函数。具体的例子进行了讨论的超核生产的当前和未来的实验感兴趣的反应。

英文摘要:

We present an overview of a fully covariant formulation for describing the production of strangeness -1 and -2 hypernuclei using probes of different kinds. This theory is based on an effective Lagrangian picture and it focuses on production amplitudes that are described via creation, propagation and decay into relevant channel of intermediate baryonic resonance states in the initial collision of the projectile with one of the target nucleons. The bound state nucleon and hyperon wave functions are obtained by solving the Dirac equation with appropriate scalar and vector potentials. Specific examples are discussed for reactions which are of interest to current and future experiments on the hypernuclear production.
