Small-momentum-transfer K−p charge exchange scattering at 30 GeV/c@@@K−p рассеяние с перезарядкой с малым передаваемым импульсом при начальном импильсе 30 ГэВ/с

The\(K^ - p \to \bar K^0 n\) charge exchange differential cross-section has been measured at 30 GeV/c with high statistical accuracy and high angular resolution. The experiment was made at the IHEP 70 GeV accelerator, by using a hodoscope hadron calorimeter to detect K L 0 . The cross-section shows a dip at small |t|, which indicates a dominance of spin-flip amplitudes in ρ and A2 exchanges in thet-channel.
