The characteristics of K∗o and production in KLop interactions below 3 GeV/c

Abstract The production features of K 0 p → K ∗0 p and K 0 p → K ∗0 p were investigated in a K L 0 p experiment using a continuous incident momentum from 0.8 to 3 GeV/ c . Both K ∗ (890) and K ∗ (890) are peripherally produced and are well described by vector and pseudoscular exchange in the t -channel. The partial contributions of the I = 0, 1 ampliitudes and their interference terms to the total KN → K ∗ N ( K N → K ∗ N ) cross sections were determined up to 5 GeV/ c using our data as well as other experimental results. This separation was done in both the s - and t -channels. The ratio σ( KN → K ∗ N )/σ( K N → K ∗ N is discussed using the separated t -channel isospin amplitudes.
