 Fractions of $K^+K^−$ pairs with $K^+$ or $K^−$ mesons from the resonance decays in pp interactions at 24 GeV/$c$ / Chliapnikov, P. V. (Serpukhov, IHEP) The Coulomb $K^+K^−$ correlations might be sensitive to non point-like $K^+K^−$ pair production due to influence of kaons from decays of resonances with relatively small widths [...] DIRAC-NOTE-2018-01. - 2018. - 4 p.
