Searching for X_{0}(2900) and X_{1}(2900) through the kaon induced reactions

Abstract

Within an effective Lagrangian approach, a theoretical study of the K^{+}p rightarrow Sigma _{c}^{++}X_{0}(2900) and K^{+}p rightarrow Sigma _{c}^{++}X_{1}(2900) reactions is carried out to search for the exotic states X_{0}(2900) and X_{1}(2900). The production process is described by the t-channel D^{-} meson exchange. The numerical results show that the total cross sections may reach up to about 0.5 nb and 25 nb for the productions 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 rightarrow Lambda _{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 experimental measurements with kaon beam.
