Using an amplitude analysis to measure the photon polarisation in $$B \rightarrow K\pi \pi \gamma $$ B→Kππγ decays
Abstract A method is proposed to measure the photon polarisation parameter $$\lambda _{\gamma }$$ λγ in $${{b}} \!\rightarrow {s} {\gamma } $$ b→sγ transitions using an amplitude analysis of $$B\!\rightarrow K\pi \pi {\gamma } $$ B→Kππγ decays. Simplified models of the $${K} {\pi } {\pi } $$ Kππ sys...
