Abstract
The differential cross section for $\gamma p\rightarrow K^+\Lambda(1520)$ 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.
