Kp scattering and hyperon excitations in a chiral quark model

  • A chiral quark-model approach is employed to study the KN scattering at low energies. The processes of Kp→Σ0π0, Λπ0 and K0n at PK≤800 MeV/c (i.e. the center mass energy W≤1.7 GeV) are investigated. The analysis shows that the Λ(1405)S01 dominates the processes Kp→Σ0π0, K0n in the energy region considered here. Around PK=400 MeV/c, the Λ(1520)D03 is responsible for a strong resonant peak in the cross section of Kp→Σ0π0 and K0n. To reproduce the data, an unexpectedly large coupling for Λ(1520)D03 to KN is needed. In contrast, the coupling for Λ(1670)S01 to KN appears to be weak, which could be due to configuration mixings between Λ(1405)S01 and Λ(1670)S01. By analyzing Kp→Λπ0, evidences for two low mass S-wave states, Σ(1480)S11 and Σ(1560)S11, seem to be available. With these two states, the reaction Kp→K0n can also be described well. However, it is difficult to understand the low masses of Σ(1480)S11 and Σ(1560)S11. The s-channel amplitudes for Kp→Λπ0 are also larger than the naive quark model expectations. The non-resonant background contributions, i.e. t-channel and/or u-channel, also play important roles in the explanation of the angular distributions due to amplitude interferences.

Kp scattering and hyperon excitations in a chiral quark model

    Corresponding author: ZHONG Xian-Hui,

Abstract: 

A chiral quark-model approach is employed to study the KN scattering at low energies. The processes of Kp→Σ0π0, Λπ0 and K0n at PK≤800 MeV/c (i.e. the center mass energy W≤1.7 GeV) are investigated. The analysis shows that the Λ(1405)S01 dominates the processes Kp→Σ0π0, K0n in the energy region considered here. Around PK=400 MeV/c, the Λ(1520)D03 is responsible for a strong resonant peak in the cross section of Kp→Σ0π0 and K0n. To reproduce the data, an unexpectedly large coupling for Λ(1520)D03 to KN is needed. In contrast, the coupling for Λ(1670)S01 to KN appears to be weak, which could be due to configuration mixings between Λ(1405)S01 and Λ(1670)S01. By analyzing Kp→Λπ0, evidences for two low mass S-wave states, Σ(1480)S11 and Σ(1560)S11, seem to be available. With these two states, the reaction Kp→K0n can also be described well. However, it is difficult to understand the low masses of Σ(1480)S11 and Σ(1560)S11. The s-channel amplitudes for Kp→Λπ0 are also larger than the naive quark model expectations. The non-resonant background contributions, i.e. t-channel and/or u-channel, also play important roles in the explanation of the angular distributions due to amplitude interferences.
