Measurement of $\gamma p \rightarrow K^ + \Lambda$ and $\gamma p \rightarrow K^ + \Sigma^0$ at photon energies up to 2.6 GeV

Gerasimov-Drell-Hearn sum rule and the discrepancy between the new CLAS and SAPHIR data

“…2. The predicted I GDH of Fit 1 and Fit 1a are much closer to the MAID prediction than those of Fit 2 and Fit 2a, indicating the consistency of the new SAPHIR data [1] to the old ones [23]. The origin of the negative values obtained from Fit 2 and Fit 2a is obvious from the evolution of both integrands shown by the dotted and dashed curves in the upper panel of Fig.…”

Kaon electromagnetic production: constraints set by new data

“…The model M1 predicts different behaviour of the polarizations in comparison with the models M2 and M3. All models do not predict proper γ + p --> K + + Λ Figure 1: Predictions of the models M1, M2, and M3 are compared with data [6,7].…”

“…This resonance can mimic the second maximum at all angles in interference with the background which need not include the hyperon resonances. A presence of the N * (1710)(N6) resonance in the models makes description of Predictions of the models H1 and H2 are compared with data [6,7].…”

(1+1)-dimensional entropic gravity

“…For clarity, the data are rebinned by a factor of two, however the attainable W resolution of the new data is a factor of 4 to 10 improvement over previous data. After normalizing for the different widths in binning, the statistical accuracy of the new data [13], blue open diamonds are CLAS data of Bradford et al [15] and green filled triangles are CLAS data of McCracken et al [17]. The thin black line is the current BnGa 2011-2 solution [11] and the thick black line is the BnGa 2011-02 solution including the new K + Λ and K + Σ 0 data [33].…”
