Abstract content

The value of the total cross section of the $pp \to pp K^{+}K^{-}$ reaction close to threshold is important for understanding the $K^+K^-$ as well as $Kp$ interactions. There is a discrepancy between the excitation function obtained from existing measurements and theoretical expectations, especially in the near-threshold region, where kaon interactions are most important. Measurement at 4.5 MeV excess energy for that reaction was performed with the COSY-11 detection system at the Cooler Synchrotron COSY. In the talk I will present the current status of research for this process together with the newly obtained upper limit for the total cross section at $Q$ = 4.5 MeV.
