“…This is placed at an internal target station of COSY, which is the COoler SYnchrotron of the Research Center Jülich [11]. We have already reported an initial analysis of the pp → ppK + K − data, from which values of the pp → ppφ cross sections were extracted [2].…”

“…Although the methods of the measurement and analysis of the pp → ppK + K − reaction have already been given in Ref. [2], for the sake of clarity the main points are repeated in Sect II. Due to the finite width of the φ, distinguishing between events corresponding to the production of this meson and the rest requires a detailed modelling of the K + K − spectrum, as described in Sect.…”

“…It is therefore an interesting but open question whether the pp → ppK + K − data from the non-φ region should be viewed, in first approximation, as scalar resonance production via pp → pp a 0 /f 0 or hyperon production through pp → K + pΛ(1405)/Σ 0 (1385). It is one aim of the present paper to study this competition by using the data obtained when investigating φ-meson production in proton-proton collisions at ANKE [2].…”

“…These can be divided mainly into two general classes involving (a) the production of a nonstrange meson that subsequently decays into KK, and (b) the associated production of KY * , where theK is formed through the decay of the hyperon Y * . The most prominent meson that is found almost exclusively in the K + K − /K 0K 0 channels is, of course the φ, and there have been measurements of the pp → ppφ → ppK + K − reaction from DISTO [1] and COSY-ANKE [2], as well as of the pn → dφ → dK + K − reaction [3]. These experiments show strength also away from the region of the φ peak that could arise from other mesons decaying into…”

The differential and total cross sections for kaon pair production in the pp → ppK + K − reaction have been measured at three beam energies of 2.65, 2.70, and 2.83 GeV using the ANKE magnetic spectrometer at the COSY-Jülich accelerator. These near-threshold data are separated into pairs arising from the decay of the φ-meson and the remainder. For the non-φ selection, the ratio of the differential cross sections in terms of the K − p and K + p invariant masses is strongly peaked towards low masses. This effect can be described quantitatively by using a simple ansatz for the K − p final state interaction, where it is seen that the data are sensitive to the magnitude of an effective K − p scattering length. When allowance is made for a small number of φ events where the K − rescatters from the proton, the φ region is equally well described at all three energies. A very similar phenomenon is discovered in the ratio of the cross sections as functions of the K − pp and K + pp invariant masses and the identical final state interaction model is also very successful here. The world data on the energy dependence of the non-φ total cross section is also reproduced, except possibly for the results closest to threshold.

“…The heavy-ion data are supplemented by proton-induced reactions on nuclei [22,23] with measurements of inclusive K + and K − production. Concerning the elementary proton-proton reactions, the recent measurements by the COSY-11 [24], TOF [25], and ANKE [26,27] Collaborations provided valuable reference data.…”

The study of the strangeness production from pp collisions plays important roles in two aspects: exploring the properties of baryon resonances involved and understanding the strangeness production from heavy ion collisions to explore the properties of high energy and high density nuclear matter. Here we review our recent studies on several most important channels for the strangeness production from pp collisions. The previously ignored contributions from Delta*(1620) and N*(1535) resonances are found to play dominant role for the pp --> n K+ Sigma+, pp --> pK+ Lambda and pp --> pp phi reactions near-thresholds. These contributions should be included for further studies on the strangeness production from both pp collisions and heavy ion collisions.Comment: Invited talk at The 10th International Conference on Nucleus-Nucleus Collisions, August 16-21, 2009, Beijing, Chin
