论文摘要
异国情调状态$ x_0（2900）$和$ x_1（2900）$ in $ k^{+} p \toσ_{c}^{++} x_ {0}（2900）$和$ k^{+k^{+} p \ toσ_{c} = {c c} {+et et s resition n e+{c c} {2有效的拉格朗日方法。包括$ t- $ channel Born术语来计算生产横截面。数值结果表明，总横截面可以分别达到约0.5 NB和25 NB，分别为$ x_0（2900）$和$ x_1（2900）$。预测的差分横截面对散射角度敏感，并且具有很强的正向增强。还计算出$ k^{+} n \toλ_{c}^{+} x_ {0,1} $的横截面，并且发现比$ k^{+} p $碰撞中的交叉部分更大。结果有助于J-Parc和Compass的可能实验。
The productions of the exotic states $ X_0(2900) $ and $ X_1(2900) $ in $K^{+}p \to Σ_{c}^{++}X_{0}(2900)$ and $K^{+}p \to Σ_{c}^{++}X_{1}(2900)$ reactions are studied within an effective Lagrangian approach. The $t-$channel Born term is included to calculate the production cross sections. The numerical results show that the total cross section may reach up to about 0.5 nb and 25 nb for the production of $ X_0(2900) $ and $ X_1(2900) $, respectively. The predicted differential cross sections are sensitive to the scattering angles and have strong forward enhancements. The cross sections for the $K^{+}n \to Λ_{c}^{+}X_{0,1}$ are also calculated and found to be larger than that in $K^{+}p$ collisions by more than one order of magnitude. The results are helpful to the possible experiments at J-PARC and COMPASS.
