论文摘要
在本文中,提出了与全局超对称性相对于全局超对称性不变的超级粒子的相互作用的超级粒子的相互作用。超级粒子的运动学是在由超空间坐标$(x_μ,θ_α,\barθ_α)$描述的扩展超空间中定义的,其中$x_μ$是纯的骨坐标,$μ= 0,\ ldots,\ ldots,3 $; $θ_α$和$ \ \barθ_α$是额外的Fermionic Grassmann值旋转器。 With the purpose of the construction of the required Lagrangian, chiral analogues of the supervector $A_μ(x,θ,\barθ)$ and superspinor $A_α(x,θ,\barθ)$, $\bar{A}_{\dotα}(x,θ,\barθ)$ gauge fields are introduced, which are also matrices in color space.本文考虑的问题是在旋转颜色的粒子在外部费米子物质场中移动的动态运动方程的进一步步骤。例如,当考虑到在热夸克 - 杜松等离子体(QGP)中引起的费米子背景场的影响时,这些运动方程非常重要。反过来,这个问题的解决方案至少在定性层面上可以使在此类复杂物理对象的外部效费事物字段中的运动中进步。
In this paper the interaction Lagrangian of a superparticle with an external chiral superfield $Φ(x,θ,\barθ)$,invariant with respect to the global supersymmetry, is proposed. The kinematics of the superparticle is defined in an extended superspace described by superspace coordinates $(x_μ,θ_α,\barθ_α)$, where $x_μ$ are pure bosonic coordinates, $μ=0,\ldots,3$; $θ_α$ and $\barθ_α$ are additional fermionic Grassmann-valued spinors. With the purpose of the construction of the required Lagrangian, chiral analogues of the supervector $A_μ(x,θ,\barθ)$ and superspinor $A_α(x,θ,\barθ)$, $\bar{A}_{\dotα}(x,θ,\barθ)$ gauge fields are introduced, which are also matrices in color space. The problem considered in this paper is the further step in deriving the dynamical equations of motion for a spin color-charged particle moving in an external fermionic matter field. These equations of motion are of fundamental importance, for example, when taking into account the influence of fermionic background fields induced in a hot quark-gluon plasma (QGP) by thermal fluctuations on the dynamics of hard color-charged partons crossing the QGP. In turn, the solution of this problem will make it possible, at least at the qualitative level, to advance in the study of the motion in the external fermion matter field of such a complex physical object as a string.
