论文摘要
在有效的Lagrangian和Regge方法中研究了质子 - 抗蛋白碰撞的奇怪和迷人的Baryon生产。我们仅包括$ t $ - 通道动力学，该动力学对于当前讨论中的衍射区域占主导地位。对于奇怪的制作，$ k $梅森的耦合常数由$ su（3）$关系确定，而其他未知参数的$ k^{*} $耦合以及形式的构造和形式的效果是由现有观察到的陌生生产的数据固定的。通过将陌生生产的振幅推断到魅力的振幅中，我们预测了魅力产生的横截面。事实证明，根据最终状态，总的交叉部分为$ 10^{4} $至$ 10^{5} $比陌生生产的$小。通过使用已知的奇怪的总横截面，$ \ sim 10^{2}μb$ for $λ\barλ$和，$ \ sim 10^{1}μb$ for $σ\barλ$预计将为$ \ sim $ \ sim $ \ sim $ for $ \ sim $ for Charm Productions的总交叉部门的总交叉部门。 10^{ - 3}μb$ for $σ_{c} \barλ_c$，$ \ sim 10^{ - 4}μb$ for $σ_{c} \barς_c$。我们的结果可以在以后的实验中测试，$ \ bar {\ text {p}} $ anda。
Strange and charmed baryon productions from proton-antiproton collisions are studied in the effective Lagrangian and Regge approaches. We include only the $t$-channel dynamics which is dominant for the diffractive region that is relevant in the present discussions. For strangeness productions, the coupling constants for $K$ meson are determined by $SU(3)$ relations while other unknown parameters for $K^{*}$ couplings and for form factors are fixed by existing observed data for strangeness productions. By extrapolating the amplitudes for strangeness productions to those for charm, we predict charm production cross sections. It turns out that the total cross sections are $10^{4}$ to $10^{5}$ smaller than those of strangeness productions, depending on the final states. By using the known total cross sections for strangeness, $\sim 10^{2} μb$ for $Λ\barΛ$ and, $\sim 10^{1} μb$ for $Σ\barΛ$ the total cross sections for charm productions are predicted to be $\sim 10^{-2} μb$ for $Λ_{c} \barΛ_c$, $\sim 10^{-3} μb$ for $Σ_{c} \barΛ_c$, and $\sim 10^{-4} μb$ for $Σ_{c} \barΣ_c$. Our results can be tested in the future experiments at $\bar{\text{P}}$ANDA.
