The differential cross section for γp→K+Λ(1520) was measured from threshold to a centre-of-mass energy of 2090 MeV at forward angles at the BGOOD experiment. The high statistical precision and resolution in centre-of-mass energy and angle allows a detailed characterisation of this low-momentum transfer kinematic region. The data agree with a previous LEPS measurement and support effective Lagrangian models that indicate that the contact term dominates the cross section near threshold.

Abstract
The differential cross section for γp→K+Λ(1520) was measured from threshold to a centre-of-mass energy of 2090 MeV at forward angles at the BGOOD experiment. The high statistical precision and resolution in centre-of-mass energy and angle allows a detailed characterisation of this low-momentum transfer kinematic region. The data agree with a previous LEPS measurement and support effective Lagrangian models that indicate that the contact term dominates the cross section near threshold.File in questo prodotto:
