Cursor 自己做了模型 PK ，Cursor 里哪个模型性价比最高？

The helicity formalism applied to the radiative decay $Λ_b^0\to pK^-γ$ is presented for the first time in this paper. The aim is to provide the necessary formalism to be able to resolve the resonant $pK^-$ structures at the photon pole by means of an amplitude analysis. Experimental effects, such as resolution, are also discussed.
